SHAREPOINT2010的用户和时间赋值和取值的方法

【转http://www.cnblogs.com/love007/archive/2012/03/14/2395624.html】

1、日期类型查询，需要转换，方法如下：

  //转换时间

   string startdate = SPUtility.CreateISO8601DateTimeFromSystemDateTime(DateTime.Now);

2、取用户类型的值

 public List<WorkManEntity> GetUsersFromSPFieldUser(SPListItem item,string key)

 {

     List<WorkManEntity> fUsers = new List<WorkManEntity>();

            

     SPFieldUser uField = item.Fields[key] as SPFieldUser;

     //此地方可以不判断为多选，如果单选可以除掉的

     if (uField.AllowMultipleValues)  // 允许多重选择 

     {

           SPFieldUserValueCollection userValues = item[key] as SPFieldUserValueCollection;

           foreach (SPFieldUserValue userValue in userValues)

           {

                if (null != userValue.User)

                {

                     WorkManEntity user = new WorkManEntity();

                     user.LookUpID = userValue.LookupId;

                     user.LookUpValue = userValue.LookupValue;

                     user.loginName = userValue.User.LoginName;

                     //add list

                     fUsers.Add(user);

                }

                    

           }

      }

           

      return fUsers;

 }

3、给用户类型赋值

 SPFieldUserValueCollection uvc = new SPFieldUserValueCollection();

 SPUser pu = web.EnsureUser(user.loginName);

  uvc.Add(new SPFieldUserValue(web, pu.ID, pu.Name));

 //用户类型

 newListitem[“加班成员”] = uvc;
