public FontFamily FontFamily { get; set; }

A font family. The default is the system dialog font.

<Button Name="btn2" FontFamily="Arial" 

void ChangeFontFamily(object sender, RoutedEventArgs e)

    ffamily = btn2.FontFamily;
    str = ffamily.ToString();
    if (str == ("Arial Black"))
        btn2.FontFamily = new FontFamily("Arial");
        btn2.Content = "FontFamily";
        btn2.FontFamily = new FontFamily("Arial Black");
        btn2.Content = "Control font family changes from Arial to Arial Black.";
