}现在问题：streamReader.ReadToEnd()返回为http://register.sdo.com/PTNew/input_pt.aspx 源码，没有进到里面去为什么？

Answer 1

是指调试没进到里面去吗？
因为你没有.net framework的源代码和pdb.

Answer 2

谢谢你
不是，比如我做了一个csdn的模拟登录可以提示登录成功但这个streamReader.ReadToEnd() 返回的还是注册页面源码是不是少了什么参数呀，但我看注册页面源码没什么参数了。

Answer 3

to :noway8881可不可以帮我看看呀，谢谢啦

Answer 4

getStream监视一下这个变量，估计是这个有问题

Answer 5

盛大注册共分三次post 提交，每次请求你都需要请求可以用工具观察下，希望对你有帮助

Answer 6

你抓包看下数据啊~~request.Referer = "http://register.sdo.com/PTNew/input_pt.aspx";
