Facebook C# SDK 在获取我/帐户时遇到问题

我正在尝试编写一个Windows服务，该服务将在运行时发布到我的Facebook页面上，并提供结果。

我刚刚下载了Facebook C# SDK v6.0.10.0，并在.Net 4.0中编写了Windows应用程序

。

我创建了一个Facebook应用程序帐户，并获得了所需的AppID和密码。

最终目标是在我的Facebook页面墙上发布此Windows服务帖子作为页面而不是应用程序用户。

当我去获取我的Facebook应用程序的帐户时，我不断收到错误。

string strAppID = "my app api id";
string strSecret = "my app secret code";
Facebook.FacebookClient fbClient = new Facebook.FacebookClient();
fbClient.AppId = strAppID;
fbClient.AppSecret = strSecret;
dynamic ac = fbClient.Get("oauth/access_token", new
{
    client_id = strAppID,
    client_secret = strSecret,
    grant_type = "client_credentials"
});
string strAccessToken = String.Empty;
strAccessToken = ac.access_token;
if (!String.IsNullOrEmpty(strAccessToken))
{
    fbClient = new Facebook.FacebookClient(strAccessToken);
    fbClient.AccessToken = strAccessToken;
    fbClient.AppId = strAppID;
    fbClient.AppSecret = strSecret;
    //Here is where it is bombing
    dynamic fbAccounts = fbClient.Get("/me/accounts");
    fbClient = new Facebook.FacebookClient(strAccessToken);
    fbClient.AccessToken = strAccessToken;
    fbClient.AppId = strAppID;
    fbClient.AppSecret = strSecret;
    dynamic me = fbClient.Get("**Name of the facebook page I am trying to post to**");
    string strPageID = String.Empty;
    strPageID = me.id;
    string strPageAccessToken = String.Empty;
    //Loop over the accounts looking for the ID that matches your destination ID (Fan Page ID)
    foreach (dynamic account in fbAccounts.data)
    {
        if (account.id == strPageID)
        {
            //When you find it, grab the associated access token and put it in the Dictionary to pass in the FB Post, then break out.
            strPageAccessToken = account.access_token;
            break;
        }
    }

    try
    {
        fbClient.AccessToken = strPageAccessToken;
        var args = new Dictionary<string, object>();
        args["message"] = "Testing 123";
        fbClient.Post("/" + strPageID + "/feed", args);
    }
    catch (Facebook.FacebookOAuthException ex)
    {
        // oauth exception occurred
    }
    catch (Facebook.FacebookApiLimitException ex)
    {
        // api limit exception occurred.
    }
    catch (Facebook.FacebookApiException ex)
    {
        // other general facebook api exception
    }
    catch (Exception ex)
    {
        // non-facebook exception such as no internet connection.
    }
}

我得到的错误是在线的：

dynamic fbAccounts = fbClient.Get("/me/accounts");

（OAuthException - #2500） 必须使用活动访问令牌来查询有关当前用户的信息。

dynamic ac = fbClient.Get("oauth/access_token", new
{
    client_id = strAppID,
    client_secret = strSecret,
    grant_type = "client_credentials"
});
