附加信息：远程服务器返回错误：（404）Not Found。 MVC

Question

我试图获取https://www.americasarmy.com/soldier/1309069

的源代码

使用以下代码：

using (WebClient client = new WebClient())
{

    ViewBag.htmlCode = client.DownloadString("https://www.americasarmy.com/soldier/1309069");
}

Answer 1

当它返回404时，源字符串将位于WebException.Response：

中

try
{
    client.DownloadString("https://www.americasarmy.com/soldier/1309069");
}
catch (WebException webex)
{
    using (var streamReader = new StreamReader(webex.Response.GetResponseStream()))
    {
        var htmlCode = streamReader.ReadToEnd(); 
    }
}
