Kill some processes by .exe file name

Question

How can I kill some active processes by searching for their .exe filenames in C# .NET or C++?

Answer 1

public void EndTask(string taskname)
{
      string processName = taskname.Replace(".exe", "");

      foreach (Process process in Process.GetProcessesByName(processName))
      {
          process.Kill();
      }
}

//EndTask("notepad");

Summary: no matter if the name contains .exe, the process will end. You don't need to "leave off .exe from process name", It works 100%.
