方式一：不啟動IE，代碼中Post

try{string url = "http:\\xxx.com" ;string postString = "uid=xx&pwd=xxx";byte[] postData = Encoding.UTF8.GetBytes(postString);HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(url));request.Method = "POST";//for some customer,use proxy, so add this.//refer:http://www.cnblogs.com/cxd4321/archive/2012/01/30/2331621.htmlrequest.ServicePoint.Expect100Continue = false;int timeout = 5000;Int32.TryParse(Settings.Default.LoginTimeOut, out timeout);if (timeout < 5000 || timeout > 15000)timeout = 5000;request.Timeout = timeout;request.ContentType = "application/x-www-form-urlencoded";request.ContentLength = postData.Length;using (Stream requestStream = request.GetRequestStream()){requestStream.Write(postData, 0, postData.Length);}HttpWebResponse response = (HttpWebResponse)request.GetResponse();StreamReader stream = new StreamReader(response.GetResponseStream(), Encoding.Default);string srcString = stream.ReadToEnd();response.Close();stream.Close();Trace.WriteLine(srcString);}catch (Exception ex){Trace.WriteLine(ex);} string url ="http://xxx.com"string postString = "parms=xx&pid=yyy";byte[] postData = Encoding.UTF8.GetBytes(postString);WebClient webClient = new WebClient();webClient.UseDefaultCredentials = true;webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");byte[] responseData = webClient.UploadData(url, "POST", postData);string srcString = Encoding.UTF8.GetString(responseData);Trace.WriteLine(srcString);

方式二：啟動IE，并模擬Post

先添加引用，COM-->Microsoft Internet Controls

再添加代碼：

string postData = "username=admin&password=admin";var ie = new InternetExplorer();object vPost, vHeaders, vFlags, vTargetFrame;vPost = null;vFlags = null;vTargetFrame = null;vHeaders = "Content-Type: application/x-www-form-urlencoded" + Convert.ToChar(10) + Convert.ToChar(13);if (!string.IsNullOrEmpty(postData))vPost = ASCIIEncoding.Default.GetBytes(postData);ie.Visible = true;string url = "http://{IP}/validate";ie.Navigate(url, ref vFlags, ref vTargetFrame, ref vPost, ref vHeaders);
