        {
            string raw = e.Result;
            string webResponse = e.Result;

            MessageBox.Show(webResponse as string);

        private void TextBox_TextChanged(object sender, TextChangedEventArgs e)
        {

        }

        class CookieAwareWebClient : WebClient
        {
            [System.Security.SecuritySafeCritical]
            private CookieContainer cookie;

            public CookieContainer Cookie { get { return cookie; } }

            public CookieAwareWebClient()
            {
                cookie = new CookieContainer();
            }

            public CookieAwareWebClient(CookieContainer givenContainer)
            {
                cookie = givenContainer;
            }
        }
    }
}

认为错误在cookie容器中，我使用的最后一个cookieaware（我尝试了超过10个cookie容器代码）

I think the error is in the cookie container, the last cookieaware i use (i have tried more than 10 cookie container codes)

推荐答案

我已经解决了我的问题使用

I have solved my problem using

request.CookieContainer = cookieJar;

那么我对第二个请求使用相同的cookieJar

then i use the same cookieJar on the second request

var request = HttpWebRequest.Create(new Uri("http://x.x.x.x/vertexweb10/webservice.svc/getallsymbols?AccountID=1122336675")) as HttpWebRequest;
request.Method = "GET";
request.CookieContainer = cookieJar;
request.BeginGetResponse(ar =>
{
    HttpWebRequest req2 = (HttpWebRequest)ar.AsyncState;
    using (var response = (HttpWebResponse)req2.EndGetResponse(ar))
    {
        using (Stream stream = response.GetResponseStream())
        {
            using (var reader = new StreamReader(stream))
            {




                //the code you need


            }
        }

    }

}, request);
