马上10.1了，都来秀秀自己的实用代码，顺便散分

[白鸽]

抛砖引玉啊，随便发个，给晚上和我有一样的朋友用，经常会想定时关机，然后放个电影看到睡着。

定时关机系统实现原理：
        主要是针对XP系统实现的，通过使用cmd的命令来实现系统的定时关机。
通过Process类来实现调用cmd，用Timer控件来监控系统时间实现时间的匹配。主要代码如下：
Process myProcess = new Process();
            myProcess.StartInfo.FileName = "cmd.exe";
            myProcess.StartInfo.UseShellExecute = false;
            myProcess.StartInfo.RedirectStandardInput = true;
            myProcess.StartInfo.RedirectStandardOutput = true;
            myProcess.StartInfo.RedirectStandardError = true;
            myProcess.StartInfo.CreateNoWindow = true;
            myProcess.Start();
            myProcess.StandardInput.WriteLine("shutdown -s -t 0");
            myProcess.Close(); 
补充cmd命令：
shutdown -s -t 0  关机命令
shutdown -l -t 0  注销命令
shutdown –a    取消命令

能不能实现自动开机呢？？？？

自动开机需要特殊的电源


可以通过网卡实现开机吧

友情幫頂。

[hj460910133]

用WMI实现关机、重启和注销，还可以远程操作。

定时关太死板了...Windows的电源管理计划没人知道？设置一下空闲关机或休眠就ok了，还写啥代码...
[/Quote]俺习惯直接打shutdown -s -t 时间...

[casker]

Parallel.For(0, Long.MaxValue, i =>
              {
                  Console.WriteLine("并行接分");              
              })

bios里面可以设置自动开机时间的啊，没用过么？

[AnwJiango]

c 一句就搞定了 system("shutdown -a");

为了这个小程序还得装 net framework...纠结。。。

关机，重启，注销操作：
先加入 using System.Runtime.InteropServices;的引用。
代码如下：
public class Shudown
{
[StructLayout(LayoutKind.Sequential, Pack = 1)]
internal struct TokPriv1Luid
{
public int Count;
public long Luid;
public int Attr;
}
[DllImport("kernel32.dll", ExactSpelling = true)]
internal static extern IntPtr GetCurrentProcess();
[DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]
internal static extern bool OpenProcessToken(IntPtr h, int acc, ref IntPtr phtok);
[DllImport("advapi32.dll", SetLastError = true)]
internal static extern bool LookupPrivilegeValue(string host, string name, ref long pluid);
[DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]
internal static extern bool AdjustTokenPrivileges(IntPtr htok, bool disall,
ref TokPriv1Luid newst, int len, IntPtr prev, IntPtr relen);

[DllImport("user32.dll", ExactSpelling = true, SetLastError = true)]

internal static extern bool ExitWindowsEx(int DoFlag, int rea);
internal const int SE_PRIVILEGE_ENABLED = 0x00000002;
internal const int TOKEN_QUERY = 0x00000008;
internal const int TOKEN_ADJUST_PRIVILEGES = 0x00000020;
internal const string SE_SHUTDOWN_NAME = "SeShutdownPrivilege";
internal const int EWX_LOGOFF = 0x00000000;
internal const int EWX_SHUTDOWN = 0x00000001;
internal const int EWX_REBOOT = 0x00000002;
internal const int EWX_FORCE = 0x00000004;
internal const int EWX_POWEROFF = 0x00000008;
internal const int EWX_FORCEIFHUNG = 0x00000010;


private static void DoExitWin(int DoFlag)
{
bool ok;
TokPriv1Luid tp;
IntPtr hproc = GetCurrentProcess();
IntPtr htok = IntPtr.Zero;
ok = OpenProcessToken(hproc, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, ref htok);
tp.Count = 1;
tp.Luid = 0;
tp.Attr = SE_PRIVILEGE_ENABLED;
ok = LookupPrivilegeValue(null, SE_SHUTDOWN_NAME, ref tp.Luid);
ok = AdjustTokenPrivileges(htok, false, ref tp, 0, IntPtr.Zero, IntPtr.Zero);
ok = ExitWindowsEx(DoFlag, 0);
}

public static void Reboot()
{
DoExitWin(EWX_FORCE | EWX_REBOOT);
}
public static void PowerOff()
{
DoExitWin(EWX_FORCE | EWX_POWEROFF);
}
public static void LogOff()
{
DoExitWin(EWX_FORCE | EWX_LOGOFF);
}
}
呃.....通过调用系统的DLL文件，加以不同的参数，来实现关机，重启，注销的操作。
调用很简单 只要调用 Reboot()重启，PowerOff()关闭，LogOff()注销 这三个函数就OK了~！
