感谢您使用微软产品。

.NET并没有提供可以修改系统时间的名字空间(namespace),您可以通过Win32 API的SetSystemTime API函数来设置系统时间:

using System;

using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential)]

public struct SystemTime

{

public ushort wYear;

public ushort wMonth;

public ushort wDayOfWeek;

public ushort wDay;

public ushort wHour;

public ushort wMinute;

public ushort wSecond;

public ushort wMiliseconds;

}

public class Win32

{

[DllImport("Kernel32.dll")]

public static extern bool SetSystemTime( ref SystemTime sysTime );

[DllImport("Kernel32.dll")]

public static extern void GetSystemTime(ref SystemTime sysTime);

}

public class TestPInvoke

{

public static void Main()

{

SystemTime sysTime =3D new SystemTime();

sysTime.wYear = 2002;

sysTime.wMonth=1;

sysTime.wDay=1;

sysTime.wDayOfWeek=1;

sysTime.wHour=1;

sysTime.wMinute=1;

sysTime.wSecond=1;

sysTime.wMiliseconds=1;

Win32.SetSystemTime(ref sysTime);

}

}

请参考microsoft.public.dotnet.framework新闻组上的帖子:
