How to display the system fonts in a combo box

Hi,

I'm developing a simple text editor using C# .net and need to display the installed system fonts

how can I get the installed system fonts and display a sample of every one of them in a comboBox ,see the example in the following image:

I think that .net already has such functionality , Isearched MSDN but didn't get it >>>> anyone knows about it ?
