使用xamarin.forms跨平台C#在设备日历上设置提醒

using Xamarin.Essentials;

if (DeviceInfo.Platform == DevicePlatform.Android || DeviceInfo.Platform == DevicePlatform.iOS)
{
    // 设备支持日历功能
}
else
{
    // 设备不支持日历功能
}

await Permissions.RequestAsync<Permissions.CalendarWrite>();

var calendarEvent = new CalendarEvent
{
    Title = "提醒标题",
    Location = "提醒地点",
    Description = "提醒描述",
    Start = DateTime.Now.AddHours(1), // 提醒开始时间
    End = DateTime.Now.AddHours(2) // 提醒结束时间
};

await Calendar.RequestAsync(new CalendarEventRequest(calendarEvent));
