解决方案
解决方案二：
你要了解RFC2188协议以及后续的扩展协议，你提交的body数据格式要符合人家的规范。

解决方案四：
cookiepostdata数据都拿到了就是不知道提交数据编码
解决方案五：
一般用UTF-8就行了。
解决方案六：
应该是你生成的数据有问题了，可以参考一下这个链接http://blog.csdn.net/flymorn/article/details/6769722
解决方案七：
http://www.telerik.com/fiddler/add-ons有fiddler抓，然后在这里下个配套的代码生成器，直接把请求拖到code页就帮你生成代码了
解决方案八：
光有错误信息，看不出多少门道啊，不如贴上部分代码
解决方案九：
是不是多了两个－－，之前我也弄这个东西，估计是那个－号的问题。多一个少一个都不行，你捉个标准的对比一下吧
解决方案十：
boundary=---------------------------7de1863814700f2这个是动态的，请求了几次这个值都不一样

解决方案十二：
这是部分代码stringboundary=DateTime.Now.Ticks.ToString("x");
这是我生成的boundary是不是跟网站上的不一样导致的
