如何利用VB.NET修改系统时间

两中方法:

1.可以用API来做:

[StructLayout (LayoutKind.Sequential)]

public struct SYSTEMTIME

{

public short Year;

public short Month;

public short DayOfWeek;

public short Day;

public short Hour;

public short Minute;

public short Second;

public short Miliseconds;

}

//api函数声明

[DllImport ("kernel32.dll", CharSet=CharSet.Ansi)]

public extern static bool SetSystemTime(ref SYSTEMTIME time);

private void button1_Click(object sender, System.EventArgs e)

{

//调用代码

SYSTEMTIME t = new SYSTEMTIME ();

t.Year = 2000;

t.Month = 1;

t.Day = 2;

t.Hour = 12-8; //这个函数使用的是0时区的时间,对于我们用+8时区的,时间要自己算一下.如要设12点，则为12-8

t.Minute = 5;

bool v = SetSystemTime(ref t);

Console.WriteLine(v.ToString());

}

2. VB.NET 特有的方法,很简单

Today=日期

TimeOfDay=时间
