复制代码 代码如下:

void UpdateContactSign()

{

string ServerPage ="http://localhost/WebService/MyService.asmx";

try

{

//ServerPage += "?op=TangramAction";

ServerPage += "/MyAction";//MyAction是WebService中的方法

string strXml="<a ObjID="9"></a>",;//第一个参数

string strData="ContactSign|990011|我的数据";//第二个参数

string res = HttpConnectToServer(ServerPage, strXml, strData);

//MessageBox.Show(res);

}

catch (Exception ex)

{

}

}

//发送消息到服务器

public string HttpConnectToServer(string ServerPage,string strXml,string strData)

{

string postData = "strXml=" + strXml+"&strData="+strData;

byte[] dataArray = Encoding.Default.GetBytes(postData);

//创建请求

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(ServerPage);

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)

{

return null;//连接服务器失败

}

return res;

}
