如何在EF代码优先方法中调用存储过程？

Question

I'm using Entity Framework with a code-first approach. Can you provide some suggestions on how to call a stored procedure from my code?

Stored procedure:

create procedure sp_GetCountry
As
Begin
    select * 
    from Country
End

Homectrol.cs :

 JanContext db = new JanContext ()

 public JsonResult GetCountry_sp()
 {
     string storedprocedure = "sp_GetCountry";
 }

Answer 1

public JsonResult GetCountry_sp()
{
    // string storedProcedure = "sp_GetCountry";
    var Country = db.Countries.SqlQuery("sp_GetCountry").ToList();
    return new JsonResult { Data = Country, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}

Answer 2

Try to use of EntityFramework Reverse POCO generator

edit the .tt file as below

 IncludeStoredProcedures = false;

to

 IncludeStoredProcedures = true;

This will create function in the DbContext with the name of storedprocedure u need to call this function this will call to the storedprocedure
