EF 怎么调用存储过程并获得output参数

1、MVC4的项目，自动会把存储过程在项目中映射为函数。

2、存储过程：

　　

 1 ALTER PROCEDURE [dbo].[P_FindAnZhiRen]
 2      @tempP_ID int output  
 3     ,@Member_ID int
 4     ,@Is_Right bit 
 5 AS
 6 
 7 
 8 set @tempP_ID =@Member_ID 
 9 BEGIN
10 
11 
12 if @Is_Right =0
13 begin
14     While(Exists(select 1 from tbMemberInfo where Parent_ID=@tempP_ID and Is_Right=0))
15     begin
16         select @tempP_ID=Member_ID from tbMemberInfo where Parent_ID=@tempP_ID and Is_Right=0
17     end     
18 end 
19 
20 
21 if @Is_Right =1
22 begin
23     if(Exists(select 1 from tbMemberInfo where Parent_ID=@tempP_ID and Is_Right=1))
24     begin
25         select @tempP_ID=Member_ID from tbMemberInfo where Parent_ID=@tempP_ID and Is_Right=1
26     end
27     
28     While(Exists(select 1 from tbMemberInfo where Parent_ID=@tempP_ID and Is_Right=0))
29     begin
30         select @tempP_ID=Member_ID from tbMemberInfo where Parent_ID=@tempP_ID and Is_Right=0
31     end     
32 end 
33 
34 END

项目代码：

　　

            var tempP_ID = new ObjectParameter("tempP_ID", typeof(Int32));
            var result = db.P_FindAnZhiRen(tempP_ID, 1, false );
            var result1 = tempP_ID.Value;
result1就是output的值
