C#: What is the proper way to change the font style (underline) from a Label at runtime?

lblName.Font = new Font(... etc. etc.

this.Font = new Font(this.Font, FontStyle.Underline);

//
    // Summary:
    //     Gets or sets a value that indicates whether the font is underlined.
    //
    // Returns:
    //     true if the font is underlined; otherwise, false. The default value is false.
    [DefaultValue(false)]
    [NotifyParentProperty(true)]
    public bool Underline { get; set; }
