这个是给的CAS集成帮助手册，我就是按照这个文件改的：全部代码如下：

{

// CAS Server访问url，根据具体项目修改
private const string CASHOST = "http://cas.***.edu.cn/cas/";
protected void Page_Load(object sender, EventArgs e)
{
System.Net.ServicePointManager.CertificatePolicy = new MyPolicy();
// Look for the "ticket=" after the "?" in the URL
string tkt = Request.QueryString["ticket"];
// This page is the CAS service=, but discard any query string residue
string service = Request.Url.GetLeftPart(UriPartial.Path);
// First time through there is no ticket=, so redirect to CAS login
if (tkt == null || tkt.Length == 0)
{
string redir = CASHOST + "login?" + "service=" + service;
Response.Redirect(redir);
return;
}
// Second time (back from CAS) there is a ticket= to validate
string validateurl = CASHOST + "serviceValidate?" +
"ticket=" + tkt + "&"+
"service=" + service;
StreamReader Reader = new StreamReader( new WebClient().OpenRead(validateurl));
string resp = Reader.ReadToEnd();
// I like to have the text in memory for debugging rather than parsing the stream
// Some boilerplate to set up the parse.
NameTable nt = new NameTable();
XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);
XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None);
XmlTextReader reader = new XmlTextReader(resp, XmlNodeType.Element, context);
string netid = null;
// A very dumb use of XML. Just scan for the "user". If it isn't there, its an error.
while (reader.Read())
{
if (reader.IsStartElement()) {
string tag = reader.LocalName;
if (tag=="user")
netid = reader.ReadString();
}
}
// if you want to parse the proxy chain, just add the logic above
reader.Close();
// If there was a problem, leave the message on the screen. Otherwise, return to original page.
if (netid == null)
{
//取得用户账号为空，按集成系统业务逻辑处理
}
else
{
//netid即为用户账号，根据账号实现集成系统的登录
}
}
}
public class MyPolicy : ICertificatePolicy
{
public bool CheckValidationResult(
ServicePoint srvPoint
, X509Certificate certificate
, WebRequest request
, int certificateProblem)
{
//Return True to force the certificate to be accepted.
return true;
} // end CheckValidationResult
} // class MyPolicy

我的意思不是把你写的代码发到这来，
你从哪复制来（或者看来）的这个ICertificatePolicy，
这个接口只需要bool CheckValidationResult(ServicePoint, X509Certificate, WebRequest, int)方法

直接这样写：ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;
