    SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain);
 
CredentialCache myCache = new CredentialCache();
 
myCache.Add(new Uri("https://www.marykayintouch.com.cn"), "Basic", myCred);
 
WebRequest wr = WebRequest.Create("https://www.marykayintouch.com.cn");

这里有很多的，抄一段给你
ASCIIEncoding encoding=new ASCIIEncoding();
string postData="Uid=uid&Password=1234";
byte[]  data = encoding.GetBytes(postData); // Prepare web request
HttpWebRequest req =
(HttpWebRequest)WebRequest.Create("http://webserver/Default.aspx");
req.Method = "POST";
req.ContentType="application/x-www-form-urlencoded";
req.ContentLength = data.Length;
Stream newStream=req.GetRequestStream();
// Send the data.
newStream.Write(data,0,data.Length);
newStream.Close();
//write response to file
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
Stream ReceiveStream = res.GetResponseStream();
byte []buffer = new byte[1024];
string filename="temp2.data";
Stream outStream = File.Create( filename );
int l;
do
{
l = ReceiveStream.Read(buffer,0,
buffer.Length);
if(l>0)
outStream.Write(buffer,0,l);
} while(l>0); outStream.Close();
