I am working on Entity Framework. How do I get the result of a stored procedure displayed in a label?

C#

using (var gb = new GaushalaDBEntities())
               {
                   var obj = gb.sp_Get_Latest_Event();
                   if (obj != null)
                   { Label1.Text= //how do i display the result from stored procedure
                   }
               }

What does your stored procedure return?

It returns a Title and an ImageURL. Both are string. It returns only one row

If your stored procedure is somehow similar to this

SQL

CREATE  PROCEDURE  [dbo].[sp_Get_Latest_Event]
AS
  SELECT 'thisIsTheLatestEvent' AS EventTitle
  , 'http://192.168.100.101:8080/rootdir/images/theEventImage.png' As EventImageUrl
GO

and you build your entity framework in a way as described here

Stored Procedure in Entity Framework[^]

then you will have something generated like this

C#

public partial class sp_Get_Latest_Event_Result
{
    public string EventTitle { get; set; }
    public string EventImageUrl { get; set; }
}

so the piece of code you are searching for should be like

C#

void TestCallToStoredProc()
{
  using (var context = new GaushalaDBEntities())
  {
    var lastestEventFromSp = context.sp_Get_Latest_Event();
    var firstItem = lastestEventFromSp.FirstOrDefault();
    Console.WriteLine(firstItem.EventTitle);
    Console.WriteLine(firstItem.EventImageUrl);
  }
}

What you get from the sp-call is a ObjectResult<t> where T is sp_Get_Latest_Event_Result

In case you set up things different, you should mention in your question

btw: if you are working with ms sql server naming a stored procedure with "sp_*" is not recommended
