Question

I’ve made a winform application that allows you to kill processes and gives a notification for a new process that starts. I need to add functionality to allow/block i.e blacklist/whitelist a process, so that it won’t run while my application is running.

Any suggestions?

If I understand your question correctly – Here is a basic example of how to work with processes.
This is based on the assumption that you have a list of process names named blackList and you want to kill any process which is on this list:

List<string> blackList = new List<string>();

// TODO: Populate the list with "black listed" processes

// Kill any process which is in the blacklist
foreach (Process process in Process.GetProcesses())
{
    if (blackList.Any(x => x.ToLowerInvariant().Equals(process.ProcessName.ToLowerInvariant())))
    {
        process.Kill();
    }
}

This should help get you started in the right direction…
