Google Calendar API V3

Question

我正尝试使用Google Calendar API V3更新我的日历。我想从C＃代码中提取日历的事件。我为Google Calendar API V3使用.Net库。

我无法让我由于某种原因请求。我试图遵循可用的代码示例，但徒劳无功。下面是我使用授权我的要求我的代码片段：

private void GetEvents() 
    { 
     var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description,MyClientId, MySecurityId); 
     var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthorization); 

     CalendarService myService = new CalendarService(auth); 
     try 
     { 
      Events result = myService.Events.List(MyCalendarId).Fetch(); 

      if (result.Items.Count > 0) 
      { 
      } 
     } 
     catch (Google.GoogleApiRequestException ex) 
     { 
      //throw ex; 
     } 
    } 

    private static IAuthorizationState GetAuthorization(NativeApplicationClient arg) 
    { 
     IAuthorizationState state = new AuthorizationState(new[] { "https://www.googleapis.com/auth/calendar.readonly" }); 

     state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);   

     if (!string.IsNullOrEmpty(refreshToken)) // refreshToken you stored in step 4 
     { 
      try 
      { 
       state.RefreshToken = refreshToken; 
       if (arg.RefreshToken(state))  // This is calling out to the OAuth servers with the refresh token getting back a session token, returns true if successful. 
       { 
        if (state.RefreshToken != refreshToken) // if the refresh token has changed, save it. 
        { 
         //PersistRefreshToken(authorization.RefreshToken); 
        } 
        return state; // Retain the authorization state, this is what will authenticate your calls. 
       } 
      } 
      catch (ProtocolException ex) { throw ex; } 
     } 
     return state; 
    } 

当执行if (arg.RefreshToken(state))我收到此异常：发送直接消息或

发生

协议异常错误

获取响应。

请帮助！
