TFS二次开发系列：八、TFS二次开发的数据统计以PBI、Bug、Sprint等为例(二)

　　上一篇文章我们编写了此例的DTO层，本文将数据访问层封装为逻辑层，提供给界面使用。

　　1.获取TFS Dto实例，并且可以获取项目集合，以及单独获取某个项目实体

        public static TFSServerBll Instance = new TFSServerBll();
        public TFSServerDto dto;
        public TFSServerBll()
        {
            dto = new TFSServerDto("http://server:8080/tfs/Project/");
        }
        public TFSServerBll(string TfsUri)
        {
            dto = new TFSServerDto(TfsUri);
        }
        /// <summary>
        /// 获取项目集合
        /// </summary>
        /// <returns></returns>
        public ProjectCollection GetProjectList()
        {
            return dto.GetProjectList();
        }
        //根据projectId获取Project实体
        public Project GetProject(int projectId)
        {
            return dto.GetProject(projectId);
        }

　　2.根据规则获取项目的PBI/Bug等信息

        /// <summary>
        /// 获取项目的所有数据
        /// </summary>
        /// <param name="project"></param>
        public void GetProjectInfo(Project project)
        {
            TfsSprint projectSprint = GetSprintInfo(project.Uri.ToString());
            GetProjectSprintPBIandBUG(projectSprint, project);
        }

        /// <summary>
        /// 获取某项目所有Sprint的PBI和BUG
        /// </summary>
        /// <param name="projectSprint"></param>
        /// <param name="project"></param>
        public void GetProjectSprintPBIandBUG(TfsSprint projectSprint, Project project)
        {
            IEnumerable<ScheduleInfo> list = GetFinalBugInfo(project);

            foreach (Sprint sprint in projectSprint.SprintList)
            {
                sprint.PBIInfo = GetSimplePbi(project.Name, sprint.SprintPath);
                if (list.Count() > 0)
                {
                    foreach (ScheduleInfo info in list)
                    {
                        if (info.Path == sprint.SprintPath)
                        {
                            sprint.BugInfo = new TfsBug() { New = info.NewBug, Done = info.Closed, opening = info.OpenBug };
                            break;
                        }
                    }
                }
                else
                {
                    sprint.BugInfo = new TfsBug() { New = 0, Done = 0, opening =0 };
                }
            }
            string s = "";
        }

        private TfsPBI GetSimplePbi(string projectName, string IterationSprint)
        {
            WorkItemCollection total = dto.GetWorkItemCollection("Product Backlog Item", projectName, "[Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection doneCollection = dto.GetWorkItemCollection("Product Backlog Item", projectName, "[State]='Done' and [Iteration Path]='" + IterationSprint + "'");
            double totaleffort = GetPBIEffort(total);
            double doneeffort = GetPBIEffort(doneCollection);
            double effortPercent = doneeffort / totaleffort;
            TfsPBI pbiinfo = new TfsPBI()
            {
                Total = total.Count,
                Done = doneCollection.Count,
                EffoctPercent = effortPercent,
                EffoctCurrent = (int)doneeffort,
                EffoctTotal = (int)totaleffort
            };
            return pbiinfo;
        }

        private TfsBug GetSimpleBug(string projectName, string IterationSprint)
        {
            WorkItemCollection total = dto.GetWorkItemCollection("Bug", projectName, "[Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection NewCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='New' and [Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection doneCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='Done' and [Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection RemovedCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='Removed' and [Iteration Path]='" + IterationSprint + "'");
            TfsBug buginfo = new TfsBug()
            {
                Total = total.Count,
                New = NewCollection.Count,
                Done = doneCollection.Count,
                Removed=RemovedCollection.Count
            };
            return buginfo;
        }

　　3.另外一些获取Bug/PBI信息的组成方式

        /// <summary>
        /// 获得某项目的BUG数量信息
        /// </summary>
        /// <param name="projectName"></param>
        /// <returns></returns>
        public TfsBug GetBugInfo(string projectName, string IterationSprint)
        {
            WorkItemCollection bugCollection = dto.GetWorkItemCollection("Bug", projectName, "[Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection bugNewCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='New' and [Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection bugApprovedCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='Approved' and [Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection bugCommittedCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='Committed' and [Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection bugDoneCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='Done' and [Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection bugRemovedCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='Removed' and [Iteration Path]='" + IterationSprint + "'");
            TfsBug buginfo = new TfsBug()
            {
                Total = bugCollection.Count,
                New = bugNewCollection.Count,
                Approved = bugApprovedCollection.Count,
                Committed = bugCommittedCollection.Count,
                Done = bugDoneCollection.Count,
                Removed = bugRemovedCollection.Count
            };
            return buginfo;
        }

        /// <summary>
        /// 获取整个项目的PBI信息
        /// </summary>
        /// <param name="projectName"></param>
        /// <returns></returns>
        public ProjectView GetAllInfo(String projectName)
        {
            WorkItemCollection total = dto.GetWorkItemCollection("Product Backlog Item", projectName, string.Empty);
            WorkItemCollection doneCollection = dto.GetWorkItemCollection("Product Backlog Item", projectName, "[State]='Done'");
            WorkItemCollection RemovedCollection = dto.GetWorkItemCollection("Product Backlog Item", projectName, "[State]='Removed'");
            double totaleffort = GetPBIEffort(total);
            double doneeffort = GetPBIEffort(doneCollection);
            double removedeffort = GetPBIEffort(RemovedCollection);
            double effortPercent = 0;
            if(totaleffort!=0)
                effortPercent = doneeffort / totaleffort;


            WorkItemCollection RiskOpenCollection = dto.GetWorkItemCollection("Impediment", projectName, "[State]='Open'");
            int riskopenCount = RiskOpenCollection.Count;


            WorkItemCollection totalBug = dto.GetWorkItemCollection("Bug", projectName, string.Empty);
            WorkItemCollection doneCollectionBug = dto.GetWorkItemCollection("Bug", projectName, "[State]='Done'");
            WorkItemCollection RemovedCollectionBug = dto.GetWorkItemCollection("Bug", projectName, "[State]='Removed'");
            int openbugCount = totalBug.Count - doneCollectionBug.Count - RemovedCollectionBug.Count;

            ProjectView view = new ProjectView() { PbiPercent = effortPercent, OpenBugCount = openbugCount, OpenRiskCount = riskopenCount, TotalPbiEffort = totaleffort};
            return view;
        }
        /// <summary>
        /// 获得某项目的PBI数量信息
        /// </summary>
        /// <param name="projectName"></param>
        /// <returns></returns>
        public TfsPBI GetPBIInfo(string projectName, string IterationSprint)
        {
            WorkItemCollection total = dto.GetWorkItemCollection("Product Backlog Item", projectName, "[Iteration Path]='" + IterationSprint + "'");
            WorkItemCollection newcollection = dto.GetWorkItemCollection("Product Backlog Item", projectName, "[State]='New' and [Iteration Path]='" + IterationSprint + "'");

            double totaleffort = GetPBIEffort(total);
            double doneeffort=GetPBIEffort(doneCollection);
            double effortPercent = doneeffort / totaleffort;
            TfsPBI pbiinfo = new TfsPBI()
            {
                Total = total.Count,
                New = newcollection.Count,
                Approved = approvedCollection.Count,

            };
            return pbiinfo;
        }
        public double GetPBIEffort(WorkItemCollection collection)
        {

            }
            return totalEff;
        }

　　4.获取Sprint,Risk等信息集合

        /// <summary>
        /// 获得某项目的Risk数量信息
        /// </summary>
        /// <param name="projectName"></param>
        /// <returns></returns>
        public List<TfsRiskInfo> GetRiskInfo(string projectName)
        {
           WorkItemCollection RiskOpenCollection = dto.GetWorkItemCollection("Impediment", projectName, "[State]='Open'");
           
            List<TfsRiskInfo> list = new List<TfsRiskInfo>();
            foreach (WorkItem item in RiskOpenCollection)
            {
                list.Add(new TfsRiskInfo() { RiskInfo=item.Description, RiskStatus="Open",RiskId=item.Id.ToString()});
            }
            return list;
        }

        /// <summary>
        /// 获取Sprint信息
        /// </summary>
        /// <param name="projectUri"></param>
        /// <returns></returns>
        public TfsSprint GetSprintInfo(String projectUri)
        {
            TeamSettings setting= dto.GetSprintInfo(projectUri);
            TfsSprint tfssprint = new TfsSprint();
            tfssprint.CurrentIterationPath=setting.CurrentIterationPath;
            tfssprint.SprintCount=setting.IterationPaths.Count();

            IEnumerable<string> ea_items =
                 from name in setting.IterationPaths.ToList()
                 where name.Contains("Sprint")
                 select name;
            List<Sprint> list = new List<Sprint>();
            foreach (string path in ea_items)
            {
                string sprintnum = path.Substring(path.LastIndexOf("Sprint") + 6).Trim();
                string sprintname ="Sprint "+sprintnum;
                if(!string.IsNullOrEmpty(sprintnum))
                    list.Add(new Sprint() { SprintName = sprintname, SprintNum = int.Parse(sprintnum), SprintPath = path });
            }
            list.Sort((x, y) => x.SprintNum - y.SprintNum);
            tfssprint.SprintList = list;
            return tfssprint;
        }
        public IEnumerable<ScheduleInfo> GetSprintDate(string projectUri)
        { 
          return dto.GetIterationDates(projectUri);
        }
        /// <summary>
        /// 获取团队成员信息
        /// </summary>
        /// <param name="projectUri"></param>
        /// <returns></returns>
        public List<TfsMember> GetMemberInfo(String projectUri)
        {
            var list=new List<TfsMember>();
            var members=dto.GetMemberInfo(projectUri);
            foreach (TeamFoundationIdentity member in members)
            {
                var m = new TfsMember() { UserName=member.DisplayName,UserSimpleName=member.UniqueName.Substring(member.UniqueName.IndexOf('\\')+1)};
                list.Add(m);
            }
            return list;
        }

        public IEnumerable<ScheduleInfo> GetFinalBugInfo(Project project)
        {
            IEnumerable<ScheduleInfo> sprintlist = GetSprintDate(project.Uri.ToString());
            int newbug = 0;
            int openbug = 0;
            int closed = 0;
            int Totalbug = 0;
            foreach (ScheduleInfo info in sprintlist)
            {

                TfsBug bug = GetSingleBug(project.Name, info.StartDate,info.EndDate);
                info.NewBug = bug.New;
                info.Closed = bug.Done;
                Totalbug += bug.New;
                openbug = Totalbug - info.Closed;
                info.OpenBug = openbug;
            }
            return sprintlist;
        }


        private TfsBug GetSingleBug(string projectName,DateTime? createdate,DateTime? enddate)
        {
            WorkItemCollection total = dto.GetWorkItemCollection("Bug", projectName, "[Created Date]>'" + createdate + "' and [Closed Date]<'"+enddate+"'");
            WorkItemCollection NewCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='New' and [Created Date]>'" + createdate + "' and [Closed Date]<'" + enddate + "'");
            WorkItemCollection doneCollection = dto.GetWorkItemCollection("Bug", projectName, "[State]='Done' and [Created Date]>'" + createdate + "' and [Closed Date]<'" + enddate + "'");
            TfsBug buginfo = new TfsBug()
            {
                Total = total.Count,
                New = NewCollection.Count,
                Done = doneCollection.Count
            };
            return buginfo;
        }

　　5.通过以上代码的封装，我们可以得到知己展示于前台的TFS数据展示。
