NET兑现Wap飞信协议

09年的时候，我用C#实现了简单的飞信协议，并开了源，详情请查看这里。直到现在还有童鞋发邮件给我向咨询或是所要代码。但是由于飞信协议有个几次的升级，我那个库基本上没什么用了。由于工作比较忙，也一直没有去管他。前两天，我用这个项目申请了sinaapp的中级开发者人证，居然侥幸通过了，所以觉得有必要更新一下代码了。

网上查了一下有关飞信协议的最新的情况，没有什么进展，我也不想自己通过抓包去分析飞信协议了，毕竟那样会比较耗时。正当我准备放弃的时候发现有人用php实现了wap飞信的协议。不看不知道，一看吓一跳，协议非常简单，总共代码也不超过100行。

我花了一小段时间，将那php的代码翻译成了C#的，测试了一下，还挺好用的，速度也挺快的。

下面是具体的代码实现，看看非常简单，占内存和CPU肯定也会非常的少。
