菜鸟求解~~~

                     Console.WriteLine(resule);
                    stream.Close();
                    rp.Close();
                    
                }
                catch (WebException ex)
                {
                    Console.WriteLine(ex.ToString());
                    Console.ReadLine();                }
                
            }

代码如上，我用循环调用这个GetResponse方法，在控制台中已经完整输出了所有信息，我想把这些信息输出到文本文件中，这个方法要怎样写呢？？
