The code below will add all the installed fonts to a ComboBox.

For this first drag and drop a combo box into your form from the toolbox and set it's name to comboBox1.

               
                foreach (FontFamily f in FontFamily.Families)
                {
//Add each font to comboBox1
                      comboBox1.Items.Add(f.Name);              
                }
