以编程方式更改系统日期

这是我找到答案的地方。;
我将其重新张贴在此处以提高清晰度。

定义此结构：

[StructLayout(LayoutKind.Sequential)]public struct SYSTEMTIME{    public short wYear;    public short wMonth;    public short wDayOfWeek;    public short wDay;    public short wHour;    public short wMinute;    public short wSecond;    public short wMilliseconds;}

将以下

extern

[Dllimport("kernel32.dll", SetLastError = true)]public static extern bool SetSystemTime(ref SYSTEMTIME st);

然后使用如下结构实例调用该方法：

SYSTEMTIME st = new SYSTEMTIME();st.wYear = 2009; // must be shortst.wMonth = 1;st.wDay = 1;st.wHour = 0;st.wMinute = 0;st.wSecond = 0;SetSystemTime(ref st); // invoke this method.
