L’exemple de code suivant montre comment utiliser le Font constructeur et les Sizepropriétés , SizeInPointset Unit . Cet exemple est conçu pour être utilisé avec un Windows Form qui contient un ComboBox nommé ComboBox1 rempli avec les chaînes « Bigger » et « Smaller ». Collez le code suivant dans le formulaire et associez la ComboBox1_SelectedIndexChanged méthode à l’événement SelectedIndexChanged du ComboBox contrôle.

private:
    void ComboBox1_SelectedIndexChanged(System::Object^ sender,
        System::EventArgs^ e)
    {

        // Cast the sender object back to a ComboBox.
        ComboBox^ ComboBox1 = (ComboBox^) sender;

        // Retrieve the selected item.
        String^ selectedString = (String^) ComboBox1->SelectedItem;

        // Convert it to lowercase.
        selectedString = selectedString->ToLower();

        // Declare the current size.
        float currentSize;

        // If Bigger is selected, get the current size from the 
        // Size property and increase it. Reset the font to the
        //  new size, using the current unit.
        if (selectedString == "bigger")
        {
            currentSize = Label1->Font->Size;
            currentSize += 2.0F;
            Label1->Font =gcnew System::Drawing::Font(Label1->Font->Name, 
                currentSize, Label1->Font->Style, Label1->Font->Unit);

        }
        // If Smaller is selected, get the current size, in
        // points, and decrease it by 2.  Reset the font with
        // the new size in points.
        if (selectedString == "smaller")
        {
            currentSize = Label1->Font->Size;
            currentSize -= 2.0F;
            Label1->Font = gcnew System::Drawing::Font(Label1->Font->Name, 
                currentSize, Label1->Font->Style);

        }
    }

private void ComboBox1_SelectedIndexChanged(System.Object sender, 
    System.EventArgs e)
