推荐答案
发送good'ol WM_CLOSE到所有实例...
Send the good'ol WM_CLOSE to all instances...
Process[] processes = Process.GetProcesses();
string thisProcess = Process.GetCurrentProcess().MainModule.FileName;
string thisProcessName = Process.GetCurrentProcess().ProcessName;
foreach (Process process in processes)
{
// Compare process name, this will weed out most processes
if (thisProcessName.CompareTo(process.ProcessName) != 0) continue;
// Check the file name of the processes main module
if (thisProcess.CompareTo(process.MainModule.FileName) != 0) continue;
if (Process.GetCurrentProcess().Id == process.Id)
{
// We don't want to commit suicide
continue;
}
// Tell the other instance to die
Win32.SendMessage(process.MainWindowHandle, Win32.WM_CLOSE, 0, 0);
}
