Detect if launched process has been closed

c# I want to Detect if a launched program has been closed. I am currently launching it with the command

 Process.Start(Environment.CurrentDirectory + @"\Card Downloader.exe");

Has anyone got a way of doing this perhaps using a different launcher?

The Process.Start() method returns a Process object. Assign it to a variable and call WaitForExit() on.

Process process = Process.Start("notepad");
process.WaitForExit();

You need to subscribe to the process Exited event, but also set the EnableRaisingEvents flag to true.

var process = Process.Start(Environment.CurrentDirectory + @"\Card Downloader.exe");
process.EnableRaisingEvents = true;
process.Exited += (sender, e) =>
{
    ...
};

If you don't set the flag, the event is raised only if the process is closed during or before the user has performed a call to the HasExited property, according to MSDN.

You can use Process.Exit event

var myProcess = new Process();
...
myProcess.Exited += new EventHandler(myProcess_Exited);
myProcess.Start();

The Process.Start method returns a Process instance. On this instance you could use some of the available methods such as WaitForExit or subscribe to the Exited event which will be triggered when this process ends.

var process = Process.Start(Environment.CurrentDirectory + @"\Card Downloader.exe"); 
process.Exited += (sender, e) =>
{
    // this will be called when the process exists
};
