Accessing SQL Server stored procedure output parameter in C#

Question

I have a simple SQL Server stored procedure:

ALTER PROCEDURE GetRowCount

(
@count int=0 OUTPUT
)

AS
Select * from Emp where age>30;
SET @count=@@ROWCOUN         


        

Answer 1

Just use ExecuteNonQuery , you can't use ExecuteReader with out parameter in this case

cmd.ExecuteNonQuery(); 

Or if you want try with ExecuteScalar and ReturnValue
