edit

i want create process ("explorer.exe C:\test") (click button 1) and kill process made infront of (click button 2). "click button 1" then "click button 2".

i predict "Process ps = Process.Start("explorer.exe C:\test");" can kill like "ps.Kill()".

but already ps(Process variable) is disappear(killed?) and can't kill created directory process("explorer.exe",@"C:\test").

how to kill i created(or start) explorer.exe process

how to kill process created by Process.Start("explorer.exe")?

Answer 1

Please try this code.

Process processToKill = Process.GetProcessById(ps.Id);
processToKill.Kill();

You can use Process.GetProcessById() to get the currently running processes, then Process.Kill() to kill a process.
