winform 调用java webservice

Question

如题，
java webservice(注册用):    http://110.70.114.58:8080/RegisterService.jws
方法：Register  ,参数：username,password两个在winform中什么调用？
MSDN源码如下，但还是不行          // Create a request for the URL. 
            WebRequest request = WebRequest.Create ("http://110.70.114.58:8080/RegisterService.jws/register?username=helpme&password=123456");
            // If required by the server, set the credentials.
            request.Credentials = CredentialCache.DefaultCredentials;
            // Get the response.
            HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
            // Display the status.
            Console.WriteLine (response.StatusDescription);
            // Get the stream containing content returned by the server.
            Stream dataStream = response.GetResponseStream ();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader (dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd ();
            // Display the content.
            Console.WriteLine (responseFromServer);
            // Cleanup the streams and the response.
            reader.Close ();
            dataStream.Close ();
            response.Close ();要啥做，求助

Answer 1

你直接添加web引用不行么 ？

Answer 2

这种方式是可以的，但服务的IP会变，我要什么通过程序的方式实现
我想把IP写入配置文件，这样好维护

Answer 3

不用web引用，如何动态调用Web Service?
