You should use SelectedIndexChanged event to catch when another font selected by user. Later You can find the font by its name and apply to txt.Font.

    InstalledFontCollection fonts;
    private void Form1_Load(object sender, EventArgs e)
    {
        InstalledFontCollection fonts = new InstalledFontCollection();
        try
        {
            foreach (FontFamily font in fonts.Families)
            {
                listBox1.Items.Add(font.Name);
            }
        }
        catch (Exception)
        {

            MessageBox.Show(e.ToString());
        }
    }

    private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        textBox1.Font = new Font(listBox1.SelectedItem.ToString(), textBox1.Font.Size);
    }
