See try,finally, Have you ever thought of anything ? , the using can generate try-finally

public class waitcursor:idisposable{    private cursor cursor;    Public WaitCursor ()    {        this.cursor = cursor.current;        Cursor.current = Cursors.waitcursor;    }    public void Dispose ()    {        cursor.current = Cursor;    }}

When you use it, you only need to:

private void Button1_Click (object sender, EventArgs e) {    using (new WaitCursor ())    {        longtimemethod ();    }}
