c# - 在 Visual Studio 中显示不友好的 HTTP 500 错误

Question

我正在编写一个将 XML 发布到 Web 服务的应用程序，并且不断收到 WebException，声称服务器上出现 HTTP 500 错误。无论如何，是否可以查看类似于 Internet Explorer 中“不友好”错误消息的错误细节？

“查看详细信息”按钮似乎没有列出我正在寻找的确切服务器响应。

谢谢。

这是代码和确切的错误消息:

static void Main(string[] args)
    {   


        //create requester
        WebRequest request = WebRequest.Create("http://server.com/service");

        //create string of xml to transfer
        string xml = "<xml>some xml goes here</xml>";

        //convert string to byte array
        byte[] transfer = Encoding.ASCII.GetBytes(xml);

        //set up method
        request.Method = "POST";

        //set up content type
        request.ContentType = "text/xml";

        //set up content length
        request.ContentLength = transfer.Length;

        //open data stream
        Stream myStream = request.GetRequestStream();

        //send the data
        myStream.Write(transfer, 0, transfer.Length);

        //Create object to capture response
       WebResponse response = request.GetResponse(); 

        //Create object to convert response to readable form
       StreamReader reader = new StreamReader(response.GetResponseStream()); 


        //Reach each line of the response stream and display on command line
       string str = reader.ReadLine();
       while(str != null)
       {
            Console.WriteLine(str);
            str = reader.ReadLine();
       }

       Console.ReadLine();

    }

捕获异常并显示消息和内部异常(如果可用)。
