C#调用Java的WebService出现500 服务器错误

最近在用C#调用Java写的WebService时，发现老是返回500 服务器错误，到底什么原因一直找不出来，

后来google了以后，找到国外的http://stackoverflow.com站点已经有人碰到过这个问题了。

转帖如下：

HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;

WebResponse wr = req.GetResponse();

 When the server returns 500 Internal Server Error, exception is thrown in req.GetResponse(). I would like the GetResponse() to accept this Response Code, it is normal for the passed url to throw this Response Code. I would like to parse the Html despite Response Code 500 Internal Server Error. Is it possible to say to GetResponse() method not to verify the Response Code?

Answer：

try
{
    HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;

    WebResponse wr = req.GetResponse();
}
catch (WebException wex)
{
    var pageContent = new StreamReader(wex.Response.GetResponseStream())
                          .ReadToEnd();
}

 可以通过上面的代码查询具体的错误信息，再进一步解决问题。
