我有一个加载页面内容的应用程序。我使用WebClient类。即使服务器返回错误,例如404,500,...,我也需要检索内容... 我需要这样的东西:
WebClient wc = new WebClient();
string pageContent;
try {
pageContent = wc.DownloadString("http://example.com/page");
}
catch (WebException ex)
{
pageContent = ex.Response.PageContent; // <-- I need this
}
答案 0 :(得分:6)
你可以试试这个:
WebClient wc = new WebClient();
string pageContent;
try {
pageContent = wc.DownloadString("http://example.com/page");
}
catch (WebException ex)
{
Stream receiveStream = ex.Response.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
StreamReader readStream = new StreamReader( receiveStream, encode );
pageContent=readStream.ReadToEnd();
}
