在C＃中的實體框架調用存儲過程

Question

This is my output looks like...

，這是我的後端

Beta_DatabaseEntities db = new Beta_DatabaseEntities(); 
table2 tb = new table2(); 

int ID; 
string Name; 
int Salary; 

public void Entry() 
{ 
     ID = Convert.ToInt16(id.Text); 
     Name = name.Text; 
     Salary = Convert.ToInt32(salary.Text); 
} 

private void insert_Click(object sender, EventArgs e) 
{ 
     Entry(); 
     tb.Id = ID; 
     tb.Name = Name; 
     tb.Salary = Salary; 
     db.table1.Add(tb); 
     db.SaveChanges(); 
     db.Database.ExecuteSqlCommand("GradeEntry "+) 
} 

我的存儲過程：

create procedure GradeEntry 
    (@ID int, @name nvarchar(50), @salary int) 
As 
Begin 
    if(@salary >= 2500) 
    Begin 
     insert into Table2 values(@ID, @name, 'A+', @salary) 
    End 
    else if(@salary >= 1000) 
    Begin 
     insert into Table2 values(@ID, @name, 'A', @salary) 
    End 
    else if(@salary >= 500) 
    Begin 
     insert into Table2 values(@ID, @name, 'B', @salary) 
    End 
    else 
    Begin 
     insert into Table2 values(@ID, @name, 'Interni', @salary) 
    End 
End 

我與實體框架的工作，但找不出瞭解如何調用在C＃中工作的存儲過程。我正在使用Visual Studio 2013

我只想從C＃使用實體框架調用存儲過程。

你幾乎有你ExecuteSqlCommand

你只需要添加EXEC，然後傳入參數：

db.Database.ExecuteSqlCommand("EXEC GradeEntry @ID, @name, @salary", 
    new SqlParameter("@ID", ID), 
    new SqlParameter("@name", Name), 
    new SqlParameter("@salary", Salary), 
) 

ExecuteSqlCommand需要對象的數組作爲參數。
