ADO.NET - The Size property has an invalid size of 0

Question

I\'m trying to get output value from DB via ADO.NET. There\'s a client code:

    using (var connection = new SqlConnection(ConnectionString))
    {

Also, you can get the actual size of the parameters by inspecting the sproc with this little command:

SqlCommandBuilder.DeriveParameters(yourCommand)

and then just foreach your way through the parameters collection.
