各位帮帮忙..急.......

Answer 1

Process process = new Process();
process.StartInfo.FileName = "shutdown.exe";
process.StartInfo.Arguments = "-s -t 0";
process.Start();

[DllImport("user32.dll")] 
private static extern int ExitWindowsEx(int x,int y); ExitWindowsEx(1,0);
或

我这里有个C++的 XP系统关机函数，不知道对你有用没
bool ShutDown()
{
HANDLE hToken;         
TOKEN_PRIVILEGES tkp;      
//Get a token for this process.         
if (!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY,&hToken))      {
error("OpenProcessToken failed!");   
return false;
} //Get the LUID for the shutdown privilege.         
LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);         
tkp.PrivilegeCount = 1;   //one privilege to set        
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;      //Get the shutdown privilege for this process.     
AdjustTokenPrivileges(hToken,FALSE,&tkp,0,(PTOKEN_PRIVILEGES)NULL,0);      //Cannot test the return value of AdjustTokenPrivileges.         
if (GetLastError() != ERROR_SUCCESS)    
{    
error("AdjustTokenPrivileges failed!");    
return false;
}
/*
if(!InitiateSystemShutdown(NULL,"系统即将关闭。",20,false,false))
error("InitiateSystemShutdown failed.");
*/
//Shut down the system and force all applications to close.         
if (!ExitWindowsEx(EWX_POWEROFF | EWX_FORCE,0))  
{    
error("ExitWindowsEx failed!");
return false;
}
return true;
}
