How to make a Font Combobox in C#?

Question

I want to make a combobox in a c# .NET 4.5 Windows Forms application (note: not WPF) that displays all the truetype installed font on the system and that every font is form

Answer 1

You can use System.Drawing.FontFamily.Families, something like this

List<string> fonts = new List<string>();

foreach (FontFamily font in System.Drawing.FontFamily.Families)
{
    fonts.Add(font.Name);
}

.................. your logic

Answer 2

Use ComboBox.DrawItem eventhandler.

public YourForm()
{
    InitializeComponent();

    ComboBoxFonts.DrawItem += ComboBoxFonts_DrawItem;           
    ComboBoxFonts.DataSource = System.Drawing.FontFamily.Families.ToList();
}

private void ComboBoxFonts_DrawItem(object sender, DrawItemEventArgs e)
{
    var comboBox = (ComboBox)sender;
    var fontFamily = (FontFamily)comboBox.Items[e.Index];
    var font = new Font(fontFamily, comboBox.Font.SizeInPoints);

    e.DrawBackground();
    e.Graphics.DrawString(font.Name, font, Brushes.Black, e.Bounds.X, e.Bounds.Y);
}

For using ComboBox.DrawItem you need set ComboBox.DrawMode = DrawMode.OwnerDrawFixed

You can achieve this by following a project published couple of years ago here, https://www.codeproject.com/Articles/318174/Creating-a-WYSIWYG-font-ComboBox-using-Csharp

But instead of doing that, you can follow the Narek Noreyan steps and adding more, use a rich text box, whose text font will be changed after selecting a font family from the combo box.

Some code snippet here,

using System.Drawing.Text;
void mainformload(object sender, EventArgs s)
{
    InstalledFontCollection inf=new      InstalledFontCollection();
    foreach(Font family font in inf.Families)
        combobox.Items.Add(font.Name); //filling the font name
    //get the font name of the rich text box text
    combobox.Text=this.richtextbox.Font.Name.ToString();
    }
void comboboxselectionchanged(object sender, EventArgs e)
{
    richtextbox.Font=new Font(combobox.text, richtextbox.Font.Size);
}
