小妹求救https访问返回结果不变的问题
环境IIS7 证书利用IIS设置里的创建自签名证书。
主要问题，我设立了一个网站用https方式访问。
获取两个参数，返回页面一个OK和Error的值。
WinForm里访问这个网站，但是每次访问得到的结果都是一个，
均返回“OK”，无论怎么修改传递的值都一样，请帮我看看哪里出问题了！

[解决办法]
用Request.QueryString取不到值，使用HttpWebResponse的GetResponse方法试试：
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream systemEntranceStream = response.GetResponseStream();
DataSet systemEntranceData = new DataSet();
systemEntranceData.ReadXml(systemEntranceStream);
[解决办法]
parameters.Add("@user_name", userName);
parameters.Add("@password", password);
