How to quickly and easily embed fonts in winforms app in C#

问题

This is probably noob territory but what the heck:

I want to embed fonts in my winforms application so that I don't have to worry about them being installed on the machine. I've searched a bit on the MSDN site and found a few hints about using native Windows API calls, for instance Michael Caplans (sp?) tutorial linked to by Scott Hanselman. Now, do I really have to go through all that trouble? Can't I just use the resource part of my app?

If not I'll probably go the installing route. In that case, can I do that programmatically? By just copying the font file to the Windows\Fonts folder?

Edit: I am aware of licencing issues, thanks for the concern though.

This is what worked for me in VS 2013, without having to use an unsafe block.

Embed the resource

Double-click Resources.resx, and in the toolbar for the designer click Add Resource/Add Existing File and select your .ttf file
In your solution explorer, right-click your .ttf file (now in a Resources folder) and go to Properties. Set the Build Action to "Embedded Resource"

Load the font into memory

Add using System.Drawing.Text; to your Form1.cs file

Add code above and inside your default constructor to create the font in memory (without using "unsafe" as other examples have shown). Below is my entire Form1.cs:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Reflection;

using System.Drawing.Text;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        [System.Runtime.InteropServices.DllImport("gdi32.dll")]
        private static extern IntPtr AddFontMemResourceEx(IntPtr pbFont, uint cbFont,
            IntPtr pdv, [System.Runtime.InteropServices.In] ref uint pcFonts);

        private PrivateFontCollection fonts = new PrivateFontCollection();

        Font myFont;

        public Form1()
        {
            InitializeComponent();

            byte[] fontData = Properties.Resources.MyFontName;
            IntPtr fontPtr = System.Runtime.InteropServices.Marshal.AllocCoTaskMem(fontData.Length);
            System.Runtime.InteropServices.Marshal.Copy(fontData, 0, fontPtr, fontData.Length);
            uint dummy = 0;
            fonts.AddMemoryFont(fontPtr, Properties.Resources.MyFontName.Length);
            AddFontMemResourceEx(fontPtr, (uint)Properties.Resources.MyFontName.Length, IntPtr.Zero, ref dummy);
            System.Runtime.InteropServices.Marshal.FreeCoTaskMem(fontPtr);

            myFont = new Font(fonts.Families[0], 16.0F);
        }
    }
}

Use your font

Add a label to your main form, and add a load event to set the font in Form1.cs:

private void Form1_Load(object sender, EventArgs e)
{
    label1.Font = myFont;
}

// specify embedded resource name
string resource = "embedded_font.PAGAP___.TTF";

// receive resource stream
Stream fontStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resource);

// create an unsafe memory block for the font data
System.IntPtr data = Marshal.AllocCoTaskMem((int)fontStream.Length);

// create a buffer to read in to
byte[] fontdata = new byte[fontStream.Length];

// read the font data from the resource
fontStream.Read(fontdata, 0, (int)fontStream.Length);

// copy the bytes to the unsafe memory block
Marshal.Copy(fontdata, 0, data, (int)fontStream.Length);

// pass the font to the font collection
private_fonts.AddMemoryFont(data, (int)fontStream.Length);

// close the resource stream
fontStream.Close();

// free up the unsafe memory
Marshal.FreeCoTaskMem(data);

I dragged and dropped a randomly downloaded font into my resources and this worked. Uses a file though. I guess you can use this as well to install fonts ?

public Form1()
{
    string filename = @"C:\lady.gaga";
    File.WriteAllBytes(filename, Resources.KBREINDEERGAMES);
    PrivateFontCollection pfc = new PrivateFontCollection();
    pfc.AddFontFile(filename);

    Label label = new Label();
    label.AutoSize = true;
    label.Font = new Font(pfc.Families[0], 16);
    label.Text = "hello world";
    Controls.Add(label);
}

Can't I just use the resource part of my app?

Yes, but need to be native resources rather than .NET resources (i.e. using rc.exe, the native resource compiler).
