WebCLient ShareCookies在客戶之間。 C＃

Helo。我想擁有幾個全部共享所有cookie的webclient實例。這是因爲我想同時下載多個項目，並且需要始終登錄。WebCLient ShareCookies在客戶之間。 C＃

這是我WebClientEx類：

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; 
     } 
    } 
}

這是我得到異常的代碼部分：

 using (WebClientEx tempWebClient = new WebClientEx()) 
     { 
      siteTemp = tempWebClient.DownloadString("http://rapideo.pl/lista"); 
     }

而這個例外是我得到這個代碼：

    Message=An exception occurred during a WebClient request.

我在我的WebCliet中添加了公共方法，它將參數中的Cookies複製到內部集合
