我想让程序在另一个程序启动或关闭时运行或关闭

Question

我希望C＃程序可以在其他程序运行时启动。例如当我运行photoshop我的程序自行运行时或当我关闭photo shop我的程序关闭时

您不能直接在简单的应用程序中执行此操作，需要创建一个Service来列出所有过程，并在创建特定过程时采取措施。 服务的主体可能如下所示：

using System.Diagnostics;

Process yourProcess;
bool triggerRunning;

public void OnUpdate()
{
   bool triggerStillRunning = false;
   //list all processes
   var processes = Process.GetProcesses();
   foreach(var p in processes)
   {
      //if trigger process is running
      if (p.ProcessName == /*Photoshop*/)
      {
         //set variable indicating that it is still running
         triggerStillRunning = true;
         //if the process was not running last update
         if(!triggerRunning)
         {
            //start your application
            yourProcess = Process.Start(/*your app*/);
            //set variable indicating that the trigger is still running
            triggerRunning = true;
         }
      }
   }
   //check if the trigger was running last update but isnt running this update 
   if (!triggerStillRunning && triggerRunning)
   {
      //kill all instances of your application
      foreach (var process in Process.GetProcessesByName("whatever"))
      {
         process.Kill();
      }
   }
}

请注意，您仍然需要将此逻辑包装在服务中。最好看一下我链接过的教程，该服务的原因必须在单独的项目和可执行文件中。
