How to create a Privatefontcollection

Question

I have some fonts that are not standard Windows, so I’m creating a PrivateFontCollection but I’m having a hard time.

These sources are used by the entire program, so I thought I’d create a Classe Static with a method get, but how could add the sources to the PrivateFontCollection? I know we use the method AddFontFile so I thought I’d add the fonts right after the user login, but I’m not getting it.

Class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing.Text;
using System.Runtime.InteropServices;
using DevExpress.CodeParser;

namespace Onee.Classes.Font
{
    public static class Fonts
    {
        private static PrivateFontCollection Font_collection;

        Font_collection.AddFontFile("C:\\Users\\thomas\\Documents\\Workspace\\Onee\\Onee Beta 1.10.16.2\\Onee\\Resources\\C_Light.otf");
        Font_collection.AddFontFile("C:\\Users\\thomas\\Documents\\Workspace\\Onee\\Onee Beta 1.10.16.2\\Onee\\Resources\\C_Bold.otf");

        public static PrivateFontCollection Collection
        {
            get { return Font.Fonts.Font_collection; }
        }
    }   
}

Form:

        private void set_font()
        {
            label4.Font = new Font(Classes.Font.Fonts.Collection.Families[1], 12, FontStyle.Bold);
            label_usuario.Font = new Font(Classes.Font.Fonts.Collection.Families[1], 12, FontStyle.Bold);
            label3.Font = new Font(Classes.Font.Fonts.Collection.Families[1], 12, FontStyle.Bold);
            label2.Font = new Font(Classes.Font.Fonts.Collection.Families[1], 12, FontStyle.Bold);
            label5.Font = new Font(Classes.Font.Fonts.Collection.Families[1], 12, FontStyle.Bold);
            label1.Font = new Font(Classes.Font.Fonts.Collection.Families[1], 12, FontStyle.Bold);

            button_servicos.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
            button_comercial.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
            button_certificados.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
            button_equipamentos.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
            button_compras.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
            simpleButton1.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
            simpleButton2.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
            button_opsistema.Font = new Font(Classes.Font.Fonts.Collection.Families[0], 15);
        }

Error:

I was able to solve it this way:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing.Text;
using System.Runtime.InteropServices;
using DevExpress.CodeParser;

namespace Onee.Classes.Font
{
    public static class Fonts
    {
        private static PrivateFontCollection Font_collection = new PrivateFontCollection();

        public static void add_font()
        {
            Font_collection.AddFontFile("C:\\Users\\thomas\\Documents\\Workspace\\Onee\\Onee Beta 1.10.16.2\\Onee\\Resources\\C_Light.otf");
            Font_collection.AddFontFile("C:\\Users\\thomas\\Documents\\Workspace\\Onee\\Onee Beta 1.10.16.2\\Onee\\Resources\\C_Bold.otf");
        }

        public static PrivateFontCollection Collection
        {
            get { return Font.Fonts.Font_collection; }
        }
    }
}

That’s the right approach?

Answer 1

Some simple improvements to implement:

1. Use@ before a string to interpret it literally. This helps in cases when there are too many characters to escape. Ex:

   Font_collection.AddFontFile("C:\\Meu\\Diretorio\\Super\\Obscuro");
   

   Vira:

   Font_collection.AddFontFile(@"C:\Meu\Diretorio\Super\Obscuro");
   

2. Whether to add sources (method add_font()) only once, consider using a static builder:

   static Fonts(){                    
       Font_collection = new PrivateFontCollection();
       Font_collection.AddFontFile(@"C:\Fonte\Um");
       Font_collection.AddFontFile(@"C:\Fonte\Dois");
   }
   

3. You do not need to create a new instance of Font for each control! Create one for a desired style and use it in all the Controls you want to own this font.

Still, some other items of its implementation are questionable (absolute paths to reference a file/resource?), but are very comprehensive and outside the scope of this question.
