HttpWebRequest post提交XMl参数请求，

public string StartPing(string pingURL)//改为一个传参数URL { StreamReader sr = null; StringBuilder sb = new StringBuilder(); string strOutput = string.Empty; string strXML = string.Empty; try { //HttpUtility.HtmlEncode strXML = BuildXML(); int len = strXML.Length; ASCIIEncoding ascii = new ASCIIEncoding(); HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(pingURL); webReq.Method = "POST"; webReq.Timeout = 3000;//超时为3秒 webReq.ContentType = "text/xml"; //string contenttype = "application/x-www-form-urlencoded";//更网站该方法支持的类型要一致 webReq.Credentials = CredentialCache.DefaultNetworkCredentials; webReq.ContentLength = len;Stream streamRequest = webReq.GetRequestStream(); byte[] bt = ascii.GetBytes(strXML); streamRequest.Write(bt, 0, len); HttpWebResponse webRes = (HttpWebResponse)webReq.GetResponse();sr = new StreamReader(webRes.GetResponseStream(), Encoding.ASCII); string ret = sr.ReadToEnd(); sb.AppendLine("\n"); sb.AppendLine(ret);if (ret.IndexOf("<boolean>0</boolean>") >= 0) { sb.AppendLine("\n\t 服务提交成功！"); } else if (ret.IndexOf("<boolean>1</boolean>") >= 0) { sb.AppendLine("\n\t 服务提交失败！"); } if (sr != null) { sr.Close(); } } catch (Exception ex) { sb.AppendLine(ex.Message); sb.AppendLine(ex.StackTrace); } finally { strOutput = sb.ToString(); if (sr != null) { sr.Dispose(); } } return strOutput; }private string BuildXML() { System.Text.StringBuilder sb = new System.Text.StringBuilder(); sb.Append("<?xml version=\"1.0\"?>"); sb.Append("<params>"); sb.AppendFormat("<title>{0}", "公告标题"); sb.Append("</title>"); sb.AppendFormat("<content>{0}", "公告内容，base64加密的"); sb.Append("</content>");sb.Append("<verify=be10c510b5f4f082dbd4268820cde895>");sb.Append("</params>"); return sb.ToString(); }

下面是服务器端接收请求方法：

加载事件里： //对应方法StartPingbyte[] byts = new byte[Request.InputStream.Length];Request.InputStream.Read(byts, 0, byts.Length);string req = System.Text.Encoding.Default.GetString(byts);req = Server.UrlDecode(req);//下面是接收到的内容//<?xml version="1.0"?><params><title>????</title><content>?????base64???</content><verify=be10c510b5f4f082dbd4268820cde895></params>*/
