輸出2個從LINQ的團場通過

Question

我想通過組類上的WorkGroup.GroupId財產

public class Employee 
{ 
    public int EmployeeID {get; set;} 
    public Group WorkGroup {get; set;} 
} 

不過，我需要輸出的組名稱屬性（可能有重複，但將是之間是相同的同組識別）

喜歡的東西（這當然不工作）：

var grps = from emp in Emps 
      group emp by emp.WorkGroup.GroupID into g 
      select new { GroupID = g.Key, Title = g.Key.WorkGroup.GroupTitle, Employees = g }; 

我找的輸出，讓我做的事：

foreach (var g in grps) 
{ 
    Console.WriteLine(g.Title + "-" + g.GroupID); 
    foreach (var e in g.Employees) 
    { 
    Console.WriteLine(e.EmployeeID); 
    } 
} 

Answer 1

僅僅通過ID和標題組：

var grps = 
    from emp in Emps 
    group emp by new 
    { 
     GroupID = emp.WorkGroup.GroupID, 
     GroupTitle = emp.WorkGroup.GroupTitle 
    } into g 
    select new 
    { 
     GroupID = g.Key.GroupID, 
     GroupTitle = g.Key.GroupTitle, 
     Employees = g 
    };
