Helo.
Я хочу иметь несколько экземпляров веб-клиента, которые разделяют все файлы cookie. Это потому, что я хочу загружать много элементов одновременно, и мне нужно все время входить в систему.
Это мой класс WebClientEx:
using System;
using System.Net;
namespace Rapideo_Client
{
/// <summary>
/// A custom WebClient featuring a cookie container
/// </summary>
class WebClientEx : WebClient
{
public static CookieContainer CookieContainer { get; private set; }
public WebClientEx()
{
CookieContainer = new CookieContainer();
}
protected override WebRequest GetWebRequest(Uri address)
{
var request = base.GetWebRequest(address);
if (request is HttpWebRequest)
{
(request as HttpWebRequest).CookieContainer = CookieContainer;
}
return request;
}
}
}
Это часть кода, где я получаю исключение:
using (WebClientEx tempWebClient = new WebClientEx())
{
siteTemp = tempWebClient.DownloadString("http://rapideo.pl/lista");
}
И это исключение, которое я получаю в этом коде:
