当我使用HttpWebRequest类从我的win应用程序调用该Web服务时出现错误远程服务器返回错误：（500）内部服务器错误

这里是我的win应用程序的代码，我在这里调用Web服务

    string strXml = "";
    strXml = "<s:Envelope xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'><s:Body><StartIndex xmlns='http://tempuri.org/' xmlns:i='http://www.w3.org/2001/XMLSchema-instance'><auth><Username>joy</Username><Password>joy</Password></auth></StartIndex></s:Body></s:Envelope>";
    string url = "http://www.bba-reman.com/Search/SearchDataIndex.asmx";
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
    req.Method = "POST";
    req.ContentType = "text/xml";
    req.KeepAlive = false;
    req.ContentLength = strXml.Length;
    StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
    streamOut.Write(strXml);
    streamOut.Close();
    StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
    string strResponse = streamIn.ReadToEnd();
    streamIn.Close();

我只是无法理解此行何时执行StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());然后收到错误远程服务器返回错误：（500）内部服务器错误

无法理解我犯错误的地方。错误是在Web服务端的代码中还是在调用代码中？

帮我解决这个问题。感谢

我推荐的是以下内容： - 你摆脱了httpwebrequest。

向您的应用程序添加一个服务引用，该引用将生成代理类。

- 最后添加此代码：

ServiceReference1.SearchDataIndexSoapClient Client = new ServiceReference1.SearchDataIndexSoapClient();
        ServiceReference1.AuthHeader authHead = new ServiceReference1.AuthHeader();
        authHead.Password = "Admin";
        authHead.Username = "Admin";

        Client.Endpoint.Binding.SendTimeout= new TimeSpan(0, 5, 00);
        Console.WriteLine(client.StartIndex(authHead));

应该是它
