namespace CalendarIntegration
{
    class Program
    {
        static void Main(string[] args)
        {
            // 谷歌日历API凭据文件的路径
            string credentialsPath = "path/to/credentials.json";

            // 用户授权的范围
            string[] scopes = { CalendarService.Scope.CalendarReadonly };

            // 从凭据文件中读取客户端ID和客户端密钥
            GoogleCredential credential;
            using (var stream = new FileStream(credentialsPath, FileMode.Open, FileAccess.Read))
            {
                credential = GoogleCredential.FromStream(stream)
                    .CreateScoped(scopes);
            }

            // 创建谷歌日历服务对象
            var service = new CalendarService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = "Calendar Integration"
            });

            // 获取日历列表
            var calendarList = service.CalendarList.List().Execute().Items;

            // 获取第一个日历的事件列表
            var events = service.Events.List(calendarList[0].Id).Execute().Items;

            // 处理日历事件
            foreach (var calendarEvent in events)
            {
                Console.WriteLine($"Summary: {calendarEvent.Summary}");
                Console.WriteLine($"Start: {calendarEvent.Start.DateTime}");
                Console.WriteLine($"End: {calendarEvent.End.DateTime}");
                Console.WriteLine();
            }
        }
    }
}
