在 Windows Phone 上使用 WebClient 时无法使用的 Cookie

我的问题是当我使用新的网络客户端将网址发送到网络服务时，它要求我登录，在搜索此问题后，我发现您需要保存cookie，但它对我不起作用。

根据您的要求，这是完整的代码

        {

        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;
            }
        }
    }
}

我认为错误出在 cookie 容器中，这是我使用的最后一个 cookieaware （我已经尝试了 10 多个 cookie 容器代码）
