如何使用.NET更新系统的日期和时间

using System;
using System.Globalization;

namespace UpdateDateTime
{
    class Program
    {
        static void Main(string[] args)
        {
            // 获取当前日期和时间
            DateTime currentDateTime = DateTime.Now;
            Console.WriteLine("当前日期和时间: " + currentDateTime);

            // 设置新的日期和时间
            DateTime newDateTime = new DateTime(2023, 1, 1, 12, 0, 0);
            Console.WriteLine("要设置的新日期和时间: " + newDateTime);

            // 设置系统时区
            TimeZoneInfo timeZone = TimeZoneInfo.Local;

            // 将新的日期和时间转换为UTC时间
            DateTime utcDateTime = TimeZoneInfo.ConvertTimeToUtc(newDateTime, timeZone);
            Console.WriteLine("转换为UTC时间: " + utcDateTime);

            // 更新系统时间
            SetSystemTime(utcDateTime);

            // 获取更新后的系统时间
            DateTime updatedDateTime = DateTime.Now;
            Console.WriteLine("更新后的系统时间: " + updatedDateTime);
        }

        // 更新系统时间的P/Invoke函数
        [System.Runtime.InteropServices.DllImport("kernel32.dll", SetLastError = true)]
        static extern bool SetSystemTime(ref SystemTime time);

        // 将DateTime转换为SystemTime结构体
        static SystemTime ToSystemTime(DateTime dateTime)
        {
            SystemTime systemTime = new SystemTime();
            systemTime.Year = (ushort)dateTime.Year;
            systemTime.Month = (ushort)dateTime.Month;
            systemTime.DayOfWeek = (ushort)dateTime.DayOfWeek;
            systemTime.Day = (ushort)dateTime.Day;
            systemTime.Hour = (ushort)dateTime.Hour;
            systemTime.Minute = (ushort)dateTime.Minute;
            systemTime.Second = (ushort)dateTime.Second;
            systemTime.Milliseconds = (ushort)dateTime.Millisecond;
            return systemTime;
        }

        // SystemTime结构体
        [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
        struct SystemTime
        {
            public ushort Year;
            public ushort Month;
            public ushort DayOfWeek;
            public ushort Day;
            public ushort Hour;
            public ushort Minute;
            public ushort Second;
            public ushort Milliseconds;
        }
    }
}
