Return Value from a Stored Procedure

Question

I am trying to get data returned from my stored procedure. This is what I have tried and absolutely nothing is coming back.

Stored Proc:

Declare @Submit_         


        

Answer 1

You're not adding the return parameter to the command:

SqlParameter pSub = new SqlParameter("@Sub_ID", SqlDbType.Int);
pSub.Direction = ParameterDirection.ReturnValue;

cmd.Parameters.Add(pSub);    // <-------------  add to command

conn.Open();
cmd.ExecuteNonQuery();

subid = Convert.ToInt32(cmd.Parameters["pSub"].Value);

Answer 2

First add parameter to cmd and use .Value to its value

 cmd.Parameters.Add(pSub);    // add parameters to command
 cmd.ExecuteNonQuery();
 subid = Convert.ToInt32(pSub.Value); // Use .Value
