You can't select a process using an `OpenFileDialog`. It selects files, not processes. If you want to kill a process then you need to get a process, so you should be looking into how to do that. In doing so, you can see what relationship a process has to a file. — user18387401, Jun 14 '22 at 08:01
You can have multiple processes with the same application file, which would you pick? You can have processes which don't have any application file. Have you though about DLLs? — Charlieface, Jun 14 '22 at 08:24

As you can see from comments, the solution is partial, but you could search if among the running processes there are some with the same name as the selected files

Microsoft.Win32.OpenFileDialog ofd = new Microsoft.Win32.OpenFileDialog();
ofd.Filter = "All files(*.*)|*.*";
ofd.Multiselect = true;
if (ofd.ShowDialog() == true)
{
    MessageBox.Show("Files Selected");
    foreach (string filename in ofd.FileNames)
    {
        var proc = System.Diagnostics.Process.GetProcesses().Where(w => w.ProcessName == System.IO.Path.GetFileNameWithoutExtension(filename)).FirstOrDefault();
        if (proc != null)
            proc.Kill(); // proc.Kill(true); to kill entire process tree
    }
}
