Question

我正在尝试创建一个不错的小型Spotify播放列表创建者，任何人都可以使用，我试图将逻辑略微分开，所以我有一种授权和创建播放列表的方法。很明显，在获得授权之前，我无法创建播放列表。

此刻我的代码如下：

    static void Main(string[] args)
    {
        PlaylistProvider provider = new PlaylistProvider(clientID:"",
            secretID: "", playlistID: "");
        bool authorized =  provider.Authorize();

        List<string> artists = new List<string>();
        artists.Add("stub");
        provider.CreatePlaylist(artists, PlaylistType.CONCERT);
    }

.Authorize（）方法授权用户，但它将用户带到网页，因此下面的调用代码在授权发生之前运行，从而引发异常。

    public bool Authorize()
    {
        AuthorizationCodeAuth auth =
new AuthorizationCodeAuth(ClientId, SecretId, "http://localhost:4003", "http://localhost:4003",
    Scope.PlaylistModifyPrivate | Scope.PlaylistReadCollaborative);

        //Once auth has been received, call AuthOnAuthReceieved method
        auth.AuthReceived += AuthOnAuthReceived;
        auth.Start();
        auth.OpenBrowser();
        return true;
    }

    private static async void AuthOnAuthReceived(object sender, AuthorizationCode payload)
    {
        AuthorizationCodeAuth auth = (AuthorizationCodeAuth)sender;
        auth.Stop();

        Token token = await auth.ExchangeCode(payload.Code);
        SpotifyWebAPI = new SpotifyWebAPI
        {
            AccessToken = token.AccessToken,
            TokenType = token.TokenType
        };
    }

我以前的解决方案是将创建播放列表添加到AuthOnAuthReceived的最后一行，但我想将逻辑分开。

我可以等待验证吗？

等待直到授权
