直接在VB.net/C#中使用资源字体

Question

如何直接使用资源字体而不在VB.net/C#中的独立应用程序[桌面应用程序]的本地文件系统中保存字体？

That's possible, you'll need to use the PrivateFontCollection.AddMemoryFont() method. For example, I added a font file named "test.ttf" as a resource and used it like this:

using System.Drawing.Text;
using System.Runtime.InteropServices;
...
public partial class Form1 : Form {
    private static PrivateFontCollection myFonts;
    private static IntPtr fontBuffer;

    public Form1() {
        InitializeComponent();
        if (myFonts == null) {
            myFonts = new PrivateFontCollection();
            byte[] font = Properties.Resources.test;
            fontBuffer = Marshal.AllocCoTaskMem(font.Length);
            Marshal.Copy(font, 0, fontBuffer, font.Length);
            myFonts.AddMemoryFont(fontBuffer, font.Length);
        }
    }

    protected override void OnPaint(PaintEventArgs e) {
        FontFamily fam = myFonts.Families[0];
        using (Font fnt = new Font(fam, 16)) {
            TextRenderer.DrawText(e.Graphics, "Private font", fnt, Point.Empty, Color.Black);
            //e.Graphics.DrawString("Private font", fnt, Brushes.Black, 0, 0);
        }
    }
}

Do note that the fontBuffer variable is static intentionally. Memory management is difficult when you use AddMemoryFont(), the memory needs to remain valid as long as the font can be used and the PrivateFontCollection is not yet disposed. Be sure not to call Marshal.FreeCoTaskMem() if you don't have that guarantee, it is a very common bug that causes very hard to diagnose text corruption. You only get an AccessViolationException when you are lucky. Keeping it valid for the life of the program is the simple solution.
