                if (Mycon.State != ConnectionState.Closed)
                {
                    Mycon.Close();
                }
            }
            catch (SqlException e)
            {
                return null;
            }

Its really hard to follow what you are saying. The meaning of most of your sentences is lost is translation.

Are you saying your code produces an error, when you try to return the value? Please post the actual error without rephrasing it. And show us which line has the error.

A screen capture might be easiest.
