谷歌日历API v3 c#不工作

Question

我正试图使用谷歌日历API V3来获取我的日历，使用c#与服务帐户其给出错误

发送直接消息或获取响应时发生错误。

下面是我的代码。

    private const string SERVICE_ACCOUNT_EMAIL = "[e-mail]";
    private const string SERVICE_ACCOUNT_PKCS12_FILE_PATH = @"D:privatekey.p12";
    static void Main(string[] args)
    {
        Test();
    }
    static void Test()
    {
        X509Certificate2 certificate = new X509Certificate2(SERVICE_ACCOUNT_PKCS12_FILE_PATH, "notasecret", X509KeyStorageFlags.Exportable);
        AssertionFlowClient provider = new AssertionFlowClient(GoogleAuthenticationServer.Description, certificate)
        {
            ServiceAccountId = SERVICE_ACCOUNT_EMAIL,
            Scope = "Calendar",
        };
        var auth = new OAuth2Authenticator<AssertionFlowClient>(provider, AssertionFlowClient.GetState);
        CalendarService c1 =new CalendarService(
            new BaseClientService.Initializer()
                        {
                            Authenticator = auth
                        });
        c1.Calendars.Get("MyCalenderID").Fetch();
    }

你的作用域应该是:

"https://www.googleapis.com/auth/" + 
Google.Apis.Calendar.v3.CalendarService.Scopes.CalendarReadonly.ToString().ToLower()
