HttpWebRequest和HttpWebResponse用法小结(2)

日期：2020-06-13 栏目：程序人生浏览：次

HttpWebResponse res = null;
WebResponse response = null;
try
{
WebResponse response = webRequest.GetResponse();
}
catch (WebException ex1)
{
res = (HttpWebResponse)ex1.Response;
}
finally
{
StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.UTF8);
string strhtml = sr.ReadToEnd();
HttpContext.Current.Response.Write(strhtml);
}

当获取服务器响应出错时，捕捉错误，最终打印出错误即可。
