如何在實體框架 6（代碼優先）中調用存儲過程？ - How to call Stored Procedure in Entity Framework 6 (Code-First)?

問題：

I am very new to Entity Framework 6 and I want to implement stored procedures in my project.我對 Entity Framework 6 很陌生，我想在我的項目中實現存儲過程。 I have a stored procedure as follows:我有一個存儲過程如下：

ALTER PROCEDURE [dbo].[insert_department]
    @Name [varchar](100)
AS
BEGIN
    INSERT [dbo].[Departments]([Name])
    VALUES (@Name)

    DECLARE @DeptId int

    SELECT @DeptId = [DeptId]
    FROM [dbo].[Departments]
    WHERE @@ROWCOUNT > 0 AND [DeptId] = SCOPE_IDENTITY()

    SELECT t0.[DeptId]
    FROM [dbo].[Departments] AS t0
    WHERE @@ROWCOUNT > 0 AND t0.[DeptId] = @DeptId
END

Department class: Department類：

public class Department
{
    public int DepartmentId { get; set; }       
    public string Name { get; set; }
}

modelBuilder 
.Entity<Department>() 
.MapToStoredProcedures(s => 
s.Update(u => u.HasName("modify_department") 
               .Parameter(b => b.Department, "department_id") 
               .Parameter(b => b.Name, "department_name")) 
 .Delete(d => d.HasName("delete_department") 
               .Parameter(b => b.DepartmentId, "department_id")) 
 .Insert(i => i.HasName("insert_department") 
               .Parameter(b => b.Name, "department_name")));

protected void btnSave_Click(object sender, EventArgs e)
{
    string department = txtDepartment.text.trim();

    // here I want to call the stored procedure to insert values
}

My problem is: how can I call the stored procedure and pass parameters into it?我的問題是：如何調用存儲過程並將參數傳遞給它？
