How to Delete Program exe file after closing program

Question

What I'm trying to do is once the user closes my program, I want the program to automatically delete the exe file. This is what I have but when I close the program I get an error that the path is not accessible, and I assume it's because at the second it is being used and can't delete.

private void Form1_FormClosed(object sender, FormClosedEventArgs e)
    {
        string path = Application.ExecutablePath;
        File.Delete(path);
    }

If anyone knows how to either execute the code once the program is fully closed or how to modify this code to make it do that, I'd appreciate it a lot.

You could execute a powershell command within C# to delete the file for you:

private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
   using (PowerShell PowerShellInstance = PowerShell.Create())
   {
      PowerShellInstance.AddScript("Remove-Item param($param1)");
      PowerShellInstace.AddParameter("param1", Application.ExecutablePath)
   }
}
