HttpWebRequest - ContentLength警告

Question

我有以下警告，我看不到任何解决方案，也许因为我很困，

以下是发送请求的代码;

string requestUrl = string.Format(xml, customerNo, -2, requestXml);
        string url = WebServiceParameters.GetString("_SERVICE") + requestUrl;
        Uri uri = new Uri(url);
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "Name", "Pass"))));
        request.Headers.Add("Content-Length: 0");
        request.ContentType = "text/xml;charset=\"utf-8\"";
        request.Accept = "text/xml";
        request.Method = "POST";
        IAsyncResult asyncResult = request.BeginGetResponse(null, null);
        asyncResult.AsyncWaitHandle.WaitOne();
        LogRequest(requestUrl);

        WebResponse response = request.GetResponse();
        StreamReader sr = new StreamReader(response.GetResponseStream(), System.Text.Encoding.GetEncoding("windows-1254"));

        string result = sr.ReadToEnd();

        LogResponse(result);

        sr.Close();
        response.Close();

这是错误;  必须使用适当的属性或方法修改“Content-Length”标头。

先谢谢

尝试在web.config

中使用它

<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="500000000" />
      </webServices>
    </scripting>
  </system.web.extensions>
