附加信息：遠程服務器返回錯誤：（404）未找到。 MVC

Question

我嘗試使用下面的代碼來獲取https://www.americasarmy.com/soldier/1309069

的源代碼：

using (WebClient client = new WebClient()) 
{ 

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

Answer 1

因爲它返回404，源字符串將在WebException.Response：

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