Facebook 离线访问 .NET SDK

我正在开发 Facebook 应用程序。我正在从我的应用程序用户那里获取离线访问权限。现在我希望我可以使用用户第一次使用我的应用程序时生成的相同令牌，并且我会将此令牌存储在我的数据库中，并且每当用户再次登录我们的网站并希望通过我们的应用程序发布一些墙贴时我们将使用相同的令牌在墙上发布。

这是我的代码

protected void Page_Load(object sender, EventArgs e)
{
    var auth = new CanvasAuthorizer { Permissions = new[] { "user_about_me", "publish_stream", "video_upload", "share_item", "photo_upload", "offline_access" } };

    var fbWebContext = FacebookWebContext.Current;
    if (fbWebContext.IsAuthorized())
    {
        try
        {
            var fb = new FacebookWebClient(fbWebContext);
            var token = fb.AccessToken;  \\ Im Getting Token This Way When its Generated From User After Getting Extended Permission
            dynamic result = fb.Get("/me");
            long id = fbWebContext.UserId;
        }
        catch (Exception ex)
        {
            if ("(OAuthException) Error validating access token: The session is invalid because the user logged out or because auth.expireSession was invoked." == ex.Message)
            {
                fbWebContext.DeleteAuthCookie();
                Session.Clear();
            }
        }
    }
}

，我使用 var token = fb.AccessToken 获取访问令牌，但是当我使用它时，它说

您的令牌已于 Unix 时间 xxxxxxxxxx 过期。

任何人都可以告诉我，如果这是请求离线访问的扩展权限后的访问令牌，那么为什么会显示“您的访问令牌已过期？”。有人可以帮忙吗？

I am working on facebook application. I am getting the offline access permission from my app user. Now I want that I can use the same tokens that generated one time when user uses first time my app and i will store this token in my db and whenever the user will login again on our site and want to publish some wall post through our app we will use the same token for publishing on wall.

Here is my code

protected void Page_Load(object sender, EventArgs e)
{
    var auth = new CanvasAuthorizer { Permissions = new[] { "user_about_me", "publish_stream", "video_upload", "share_item", "photo_upload", "offline_access" } };

    var fbWebContext = FacebookWebContext.Current;
    if (fbWebContext.IsAuthorized())
    {
        try
        {
            var fb = new FacebookWebClient(fbWebContext);
            var token = fb.AccessToken;  \\ Im Getting Token This Way When its Generated From User After Getting Extended Permission
            dynamic result = fb.Get("/me");
            long id = fbWebContext.UserId;
        }
        catch (Exception ex)
        {
            if ("(OAuthException) Error validating access token: The session is invalid because the user logged out or because auth.expireSession was invoked." == ex.Message)
            {
                fbWebContext.DeleteAuthCookie();
                Session.Clear();
            }
        }
    }
}

I get the access token using var token = fb.AccessToken but when I use it it says

Your Token is Expired at Unix Time xxxxxxxxxx.

Can anyone please tell me anyone if this is the access token after requesting the extended permission of offline access then why is it saying "Your Access token is Expired?". Can anyone please help?
