C#調用java的WebService出現500 服務器錯誤

最近在用C#調用Java寫的WebService時，發現老是返回500 服務器錯誤，到底什么原因一直找不出來，

后來google了以后，找到國外的http://stackoverflow.com站點已經有人碰到過這個問題了。

轉帖如下：

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();}

可以通過上面的代碼查詢具體的錯誤信息，再進一步解決問題。
