Kill some processes by .exe file name

Question

Quick Answer:

foreach (var process in Process.GetProcessesByName("whatever"))
{
    process.Kill();
}

(leave off .exe from process name)

My solution is to use Process.GetProcess() for listing all the processes.

By filtering them to contain the processes I want, I can then run Process.Kill() method to stop them:

var chromeDriverProcesses = Process.GetProcesses().
    Where(pr => pr.ProcessName == "chromedriver"); // without '.exe'
    
foreach (var process in chromeDriverProcesses)
{
     process.Kill();
}

Update:

In case if you want to do the same in an asynchronous way (using the C# 8 Async Enumerables), check this out:

const string processName = "chromedriver"; // without '.exe'
await Process.GetProcesses()
             .Where(pr => pr.ProcessName == processName)
             .ToAsyncEnumerable()
             .ForEachAsync(p => p.Kill());

Note: using async methods doesn't always mean code will run faster.
The main benefit is that the foreground thread will be released while operating.

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

If you have the process ID (PID) you can kill this process as follow:

Process processToKill = Process.GetProcessById(pid);
processToKill.Kill();
