implement restart as Administrator in C# console app

Question

I have a console app that deletes some files, and it can only do that if it is started as administrator.

When the app is started not as administrator I would prefer for it to:

1. close
2. and start again,
3. and the user to get the "start as administrator Yes/No dialog box"

(kinda like notepad++ when you try to edit a certain file, it asks you if you want to restart as administrator)

is this something easy to do in C#?

Thanks to the wise advice in the comments, I managed to get it done.

static void Main()
{
    if (!IsAdministrator())
    {
        Console.WriteLine("restarting as admin");
        StartAsAdmin(Assembly.GetExecutingAssembly().Location);
        return;
    }
    ...
}

public static bool IsAdministrator()
{
    var identity = WindowsIdentity.GetCurrent();
    var principal = new WindowsPrincipal(identity);
    return principal.IsInRole(WindowsBuiltInRole.Administrator);
}

public static void StartAsAdmin(string fileName)
{
    var proc = new Process
    {
        StartInfo =
        {
            FileName = fileName, 
            UseShellExecute = true, 
            Verb = "runas"
        }
    };

    proc.Start();
}
