.NET进程间“事件”

将good'ol wm_发送到所有实例…

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);
}

System.Diagnostics.Process类有几个方法可以使用。

process.getprocessbyname将允许您枚举所有实例:

然后process.closemainwindow或process.close将关闭它们:
