         string con = "Data Source=10.0.0.249\\sql2005;Initial Catalog=master;Persist Security Info=True;User ID=sa;Password=sa";
            SqlConnection myConn = new SqlConnection(con);
            SqlCommand myCommand = new SqlCommand(str, myConn);
            try
            {
                myConn.Open();
                myCommand.ExecuteNonQuery();
                Console.WriteLine("SQL 语句执行完成。", "MyProgram");
            }
            catch (System.Exception ex)
            {
                Console.WriteLine(ex.ToString(), "MyProgram");
            }
            finally

                {
                    myConn.Close();
