httpwebrequest怎样可以设置成"不显示友好http错误信息"的效果呢

number321 2012-05-30 09:33:41

默认IE浏览器高级设置里的"显示友好的HTTP错误信息"是勾上的.
这样如果访问的ASP页面本身出现错误时,只会提示"500内部服务器错误"
不会显示具体的ASP报错.

只有把这个勾去掉后才会显示具体错误.

httpwebrequest在访问这种有问题的ASP页面时,返回的异常信息也是"500内部服务器错误",相当于勾选了显示友好的HTTP错误信息.
那么有没有办法设置成不显示好友HTTP信息呢,我想获得服务器返回的具体ASP报错.

HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("http://192.168.0.200/index2.html");

try

{

  HttpWebResponse respon = (HttpWebResponse)myReq.GetResponse();

}

catch (WebException ex)

{

    HttpWebResponse res = (HttpWebResponse)ex.Response;

    Stream rs = res.GetResponseStream();

    Encoding encode = Encoding.GetEncoding("utf-8");

    StreamReader readStream = new StreamReader(rs, encode);

    string tmp = readStream.ReadToEnd();

    res.Close();

    readStream.Close();

    MessageBox.Show(tmp);

}

输出是



<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<html><head>

<title>404 Not Found</title>

</head><body>

<h1>Not Found</h1>

<p>The requested URL /index2.html was not found on this server.</p>

</body></html>

将就着看看吧
