AgileEAS 5.0新增功能展示

 此随笔主旨在已经了解EAS平台搭建项目的基础上,利用EAS 5.0的新增功能快速、专业的开发属于自己的.NET企业级项目:

具体方案建立过程见【H.I.D的博客  --http://www.cnblogs.com/HelloWang/archive/2013/03/23/2977845.html】博客

一、新增系统风格 【我的桌面】

效果如下:

双击打开对应模块,操作快捷方便,界面之爽!!

二、新增Linq写法

1.Lambda 表达式 

 1    /// <summary>
 2         /// EAS 5.0 Linq  3         /// </summary>
 4         public void GetCommonPre()  5  {  6             Query<CommonPre> query = new Query<CommonPre>();  7             var q = from c in query  8                     select c;  9             //1. 求和
10             decimal totalCash = q.Sum(p => p.Cash); 11             //2. OrderBy、 Skip、Take ....
12             var v2 = q.OrderBy(p => p.ID).Skip(20).Take(10).Select(c => new { CName = c.DrugName, Num = c.Number }); 13             foreach (var item in v2) 14  { 15                 //....
16  } 17         }

 

2.连接 

 1    /// <summary>
 2         /// EAS 5.0 连接  3         /// </summary>
 4         public void GetData()  5  {  6             DataEntityQuery<CommonPre> com = new DataEntityQuery<CommonPre>();  7             DataEntityQuery<RegCode> reg = new DataEntityQuery<RegCode>();  8             //1 .连接
 9             var v1 = from c in com 10                      from d in reg 11                      where c.ID > 100 && d.Doctor == 5
12                      select new
13  { 14                          code = c.DrugCode, 15                          drug = c.DrugName, 16                          name = d.Name, 17                          eventt = d.EventTime 18 
19  }; 20             foreach (var item in v1) 21  { 22                 //.....
23  } 24             //2.左外连接
25             var v2 = from c in com 26                      from d in reg.Where(p => p.ISPreNum == 0).Where(p => p.Doctor == c.ID).DefaultIfEmpty() 27                      where c.ID > 10
28                      select new
29  { 30                          drugname = c.DrugName, 31                          code = c.DrugCode, 32                          name = d.Name 33  }; 34             foreach (var item in v2) 35  { 36                 //.....
37  } 38             //3.笛卡尔积
39             var v3 = from c in com 40                      from d in reg 41                      where c.ID < 10 && d.Name.Equals("张三") 42                      select new
43  { 44                          reg = d.Code, 45                          drugname = c.DrugName, 46                          cash = c.Cash 47  }; 48             foreach (var item in v3) 49  { 50                 //.....
51  } 52         }

 3.Select

 1   /// <summary>
 2         /// EAS 5.0 Select  3         /// </summary>
 4         public void SelectData()  5  {  6             DataEntityQuery<CommonPre> comPre = new DataEntityQuery<CommonPre>();  7             var items = comPre.Select(p => new
 8  {  9                 name = p.DrugName, 10                 cash = p.Cash 11  }); 12             int count = items.Count(); 13             foreach (var item in items) 14  { 15                 //.... 
16  } 17         }

 4.Group by

 1   /// <summary>
 2         /// EAS 5.0 Groupby  3         /// </summary>
 4         public void GroupByData()  5  {  6             DataEntityQuery<CommonPre> comPre = new DataEntityQuery<CommonPre>();  7             var items = from c in comPre  8  group c by c.ID  9  into g 10                             select new
11  { 12                                 name = DrugName, 13                                 totalcash = g.Sum(o => o.Cash), 14                                 Avg = g.Average(o => o.Cash), 15                                 Max = g.Max(o => o.Number), 16                                 Min = g.Min(o => o.Number) 17  }; 18             foreach (var item in items) 19  { 20                 System.Console.WriteLine(string.Format("Name={0},totalcash={1},Avg={2},Max={3},Min={4} ", item.name, item.totalcash, item.Avg, item.Max, item.Min)); 21  } 22         }

 5.Delete、Update、Count...

 1   /// <summary>
 2         /// EAS 5.0 Delete Insert Update Count  3         /// </summary>
 4         public void ContextData()  5  {  6             DataEntityQuery<CommonPre> comPre = new DataEntityQuery<CommonPre>();  7             //查询

12  } 13             //Delete
14             int countDelete = comPre.Delete(o => o.ID > 20); 15             //Update
16             int countUpdate = comPre.Update(p => new CommonPre { DrugName = "精乌胶囊", Cash = 75.2m }, p => p.ID > 20); 17             //CommonPre insertComPre = new CommonPre(); 18             //insertComPre.ID = this.GetMaxID(); 19             //insertComPre.DrugName = "陈皮"; 20             //insertComPre.Spec = "30g/瓶"; 21             //insertComPre.Insert(); 22
