注意，这个方法仅仅适用于:该post页面处于websercive 站点下，或者是与webservice同属于一个主站点，即在iis里属于同一主站点的同级虚拟目录。

protected void btnSynData_Click(object sender, EventArgs e) {string wsUrl = http://127.0.0.1:1113/yingxiao/clfbxd.asmx/huixie;//注意：huixie 是webservice的方法名 string postData = 我是谁;

HttpConnectToServer(wsUrl, postData); } /// summary /// 发送消息到ws服务器 /// /summary /// param name=ServerPage/param /// param name=strXml/param /// returns/returns public string HttpConnectToServer(string ServerPage, string strXml) { string postData = strXml= + strXml;

byte dataArray = Encoding.Default.GetBytes(postData); //创建请求 HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(ServerPage);

request.Credentials = CredentialCache.DefaultCredentials; request.CookieContainer = new CookieContainer(); request.Method = POST; request.ContentLength = dataArray.Length; request.ContentType = application/x-www-form-urlencoded; //创建输入流 Stream dataStream = null;

try { dataStream = request.GetRequestStream(); } catch (Exception) { return null;//连接服务器失败 } //发送请求 dataStream.Write(dataArray, 0, dataArray.Length); dataStream.Close(); //读取返回消息 string res = string.Empty; try { HttpWebResponse response = (HttpWebResponse)request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8); res = reader.ReadToEnd(); reader.Close(); } catch (Exception ex) { throw new Exception(ex.Message); } return res; }
