How can I set the font source to system font source and custom collection font source?

The source of the font can be set to system font and custom collection source. It can be done as follows :

[C#]

//System font source fontListBox.FontsSource = "System"; //custom font collection source FontCollection collection = new FontCollection(); collection.Add(new FontFamily("Albertus")); collection.Add(new FontFamily("Times")); collection.Add(new FontFamily("Tahoma")); collection.Add(new FontFamily("Webdings")); collection.Add(new FontFamily("Arial")); collection.Add(new FontFamily("Algerian")); fontListBox.FontsSource = collection;
