Using custom fonts in C# application

Recently I wanted to embed custom fonts in my application. After some googling and mixing the solution is this

[DllImport("gdi32.dll")]
private static extern IntPtr AddFontMemResourceEx(IntPtr pbFont, uint cbFont, IntPtr pdv, [In] ref uint pcFonts);

public static PrivateFontCollection private_fonts = new PrivateFontCollection();
public static void LoadFont()
{
// Use this if you can not find your resource System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();
string resource = "Test.Images.MyFont.ttf";
// receive resource stream
Stream fontStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resource);

//create an unsafe memory block for the data
System.IntPtr data = Marshal.AllocCoTaskMem((int)fontStream.Length);
//create a buffer to read in to
Byte[] fontData = new Byte[fontStream.Length];
//fetch the font program 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);

// We HAVE to do this to register the font to the system (Weird .NET bug !)
uint cFonts = 0;
AddFontMemResourceEx(data, (uint)fontData.Length, IntPtr.Zero, ref cFonts);

//pass the font to the font collection
private_fonts.AddMemoryFont(data, (int)fontStream.Length);
//close the resource stream
fontStream.Close();
//free the unsafe memory
Marshal.FreeCoTaskMem(data);

}

...

// Apply  font to TextEdit

LoadFont();
tbPassword.PasswordChar = 'A';
tbPassword.Font = new Font(private_fonts.Families[0], 8);

...

Add your font file to project resources :

Embed Font

Use the code above and you are ready to go. This solution also works with DevExpress edit components
