用C#的WMI编程，可以远程控制服务器

1、调用控制面板选项：timedate.cpl
2、使用WMI进行改变：
using System;
using System.Runtime.InteropServices;

namespace ConsoleApplication20
{
[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 wMilliseconds;

public DateTime ToDateTime()
{
return new DateTime(wYear, wMonth, wDay, wHour, wMinute, wSecond,
wMilliseconds);
}
}

class Win32API
{
[DllImport("Kernel32.dll")]
public static extern bool SetSystemTime(ref SYSTEMTIME st);
[DllImport("Kernel32.dll")]
public static extern void GetSystemTime(out SYSTEMTIME st);
}

class Class1
{
[STAThread]
static void Main(string[] args)
{
SYSTEMTIME st;
Win32API.GetSystemTime(out st); // gets current time
Console.WriteLine( st.ToDateTime().ToLocalTime().ToString() );
st.wMinute++; // Adjust minutes
if (!Win32API.SetSystemTime(ref st)) // sets system time
Console.WriteLine("An error occured setting the system time");
Win32API.GetSystemTime(out st); // gets current time
Console.WriteLine( st.ToDateTime().ToLocalTime().ToString() );
Console.ReadLine();
}
}
}

其中第一种方法比较简单，你可以参考：

DataTime.Now = new DataTime(---);

[Soking]

or
DataTime.Now = DataTime.Prase("---");

[ismezy2002]

using System.Runtime.InteropServices;

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 Milliseconds;
}

public MyDateTime
{
public MyDateTime()
{
}
[DllImport("Kernel32.dll", CharSet=CharSet.Auto)]
private static extern bool SetSystemTime(ref SystemTime st);

public bool SetSystemTime(int year,int mon,int day,int hour,int min,int sec)
{
SystemTime st = new SystemTime();
st.Year = (short)year;
st.Month = (short)mon;
st.Day = (short)day;
st.Hour = (short)hour;
st.Minute = (short)min;
st.Second = (short)sec;
return SetSystemTime(ref st);
}
}
