查詢組名稱

Question

我想按組的所有用戶名稱。我試過了：

var query = from u in db.Users 
      group p by u.UserGroup 
      select u.FullName; 

我該如何解決？

Answer 1

這將返回匿名對象的順序，方含用戶組和所有的名字從該組中：

var query = from u in db.Users 
      group u by u.UserGroup into g 
      select new { 
       UserGroup = g.Key, 
       Names = g.Select(x => x.FullName) 
      };
