從兩個表

Question

我在我的數據庫中的兩個表獲取數據：

Employee(EmployeeID, EmployeeName, EmployeeGroup) 
Group(GroupID, GroupName, GroupLeader) 

EmployeeGroup對應於羣ID
GroupLeader對應EmployeeID爲

我要選擇列：

EmpoyeeID, EmployeeName, LeaderName(Customer name) 

我怎樣才能做到這一點？

Answer 1

var list = dataModel.Employee.Join(dataModel.Group, 
    e => e.EmployeeGroup, 
    g => g.GroupID, 
    (e, g) => 
     new                       
       { 
       EmpoyeeID= e.EmpoyeeID, 
       EmployyeName= e.EmployyeName, 
       LeaderName= g.GroupLeader.EmployyeName     
});
