如何使WebClient支持Session

 

public class HttpWebClient : WebClient
{
    /// <summary>
    /// CookieContainer
    /// </summary>
    private static CookieContainer _CookieContainer = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        // 判断是不是HttpWebRequest.只有HttpWebRequest才有此属性 
        if (request is HttpWebRequest)
        {
            HttpWebRequest httpRequest = request as HttpWebRequest;
            httpRequest.CookieContainer = _CookieContainer;
            _CookieContainer.SetCookies(new Uri("http://127.0.0.1:1010/"), "ASP.NET_SessionId=zev02g55ynp5kp55xm3ihj45");
        }
        return request;
    }
}
