将microsoft.graph.customTimeZone转换为TimeZoneInfo

using System;
using Microsoft.Graph;

public class TimeZoneConverter
{
    public static TimeZoneInfo ConvertCustomTimeZoneToTimeZoneInfo(CustomTimeZone customTimeZone)
    {
        // 创建一个 TimeZoneInfo 对象
        TimeZoneInfo timeZoneInfo = TimeZoneInfo.CreateCustomTimeZone(
            customTimeZone.Id,
            customTimeZone.BaseUtcOffset.TotalMinutes,
            customTimeZone.DisplayName,
            customTimeZone.StandardOffset.TotalMinutes,
            customTimeZone.DaylightOffset.TotalMinutes);

        return timeZoneInfo;
    }
}

// 示例用法
CustomTimeZone customTimeZone = new CustomTimeZone
{
    Id = "CustomTimeZoneId",
    BaseUtcOffset = TimeSpan.FromHours(-8),
    DisplayName = "Pacific Standard Time",
    StandardOffset = TimeSpan.FromHours(-8),
    DaylightOffset = TimeSpan.FromHours(-7)
};

TimeZoneInfo timeZoneInfo = TimeZoneConverter.ConvertCustomTimeZoneToTimeZoneInfo(customTimeZone);
Console.WriteLine($"TimeZone ID: {timeZoneInfo.Id}");
Console.WriteLine($"DisplayName: {timeZoneInfo.DisplayName}");

TimeZoneInfo systemTimeZone = TimeZoneInfo.FindSystemTimeZoneById(customTimeZone.Id);
if (systemTimeZone != null)
{
    Console.WriteLine($"System Time Zone ID: {systemTimeZone.Id}");
}
else
{
    Console.WriteLine("Invalid Time Zone ID");
}
