How to get PID of started App in C#

I have got a few pairs of the identical apps.

It looks like

Pair 1: App A + App B

Pair 2: App A + App B

and etc

Each App A starts App B from its folder. (They are both at the same folder.)

So I start it like this

Code of App A

Process p = new Process();
p.StartInfo.FileName = FileManager.AppDirectoryName + "\\" + AppB;
p.Start();

And I also stop App B like this.

foreach (Process p in Process.GetProcesses())
{  
    if (p.ProcessName == AppB)
    {
        p.Kill();
        return;
    }
}

The problem is that at the same time could be many App B executing so this method does not allow to detect target App B to kill.

I assume to use PID of App B to kill it. But I don't know how to obtain PID at the moment to start App B...

Any clue?

Save a reference to the Process object:

Process p = new Process();
p.StartInfo.FileName = @"c:\windows\notepad.exe";
p.Start();

// ...

p.Kill();

or remember its PID:

Process p = new Process();
p.StartInfo.FileName = @"c:\windows\notepad.exe";
p.Start();

long pid = p.Id;

// ...

Process.GetProcessById(pid).Kill();

After starting the app, the Id property on the Process object will indicate the PID of the newly started process

var PID = p.Id;
