谷歌日历API-创建/插入/添加事件-C#-错误403

谷歌日历API-创建/插入/添加事件-C#-错误403,c#,google-calendar-api,C#,Google Calendar Api,我正试图创建一个C#工具来操纵我的谷歌日历。 该工具已成功从API接收事件,但在尝试创建事件时出现错误: Google.GoogleApiException: 'Google.Apis.Requests.RequestError Insufficient Permission: Request had insufficient authentication scopes. [403] Errors [ Message[Insufficient Permission: Request ha

我正试图创建一个C#工具来操纵我的谷歌日历。 该工具已成功从API接收事件,但在尝试创建事件时出现错误:

Google.GoogleApiException: 'Google.Apis.Requests.RequestError
Insufficient Permission: Request had insufficient authentication scopes. [403]
Errors [
    Message[Insufficient Permission: Request had insufficient authentication scopes.] Location[ - ] Reason[insufficientPermissions] Domain[global]
]
我有两个按钮:一个用于创建事件,另一个用于显示即将到来的事件。请注意,我尝试了3种不同的方法来添加一个事件,但都有相同的错误结果
