c# - 从资源中添加字体文件

Question

我使用以下代码添加了自定义字体:

PrivateFontCollection pfc = new PrivateFontCollection();
pfc.AddFontFile("C:\\Path To\\YourFont.ttf");
label1.Font = new System.Drawing.Font(pfc.Families[0], 16, FontStyle.Regular);

我在资源中添加了字体文件。如何从资源中使用 addFontFile 添加？

private static void AddFontFromResource(PrivateFontCollection privateFontCollection, string fontResourceName)
{
    var fontBytes = GetFontResourceBytes(typeof (App).Assembly, fontResourceName);
    var fontData = Marshal.AllocCoTaskMem(fontBytes.Length);
    Marshal.Copy(fontBytes, 0, fontData, fontBytes.Length);
    privateFontCollection.AddMemoryFont(fontData, fontBytes.Length);
    // Marshal.FreeCoTaskMem(fontData);  Nasty bug alert, read the comment
}

private static byte[] GetFontResourceBytes(Assembly assembly, string fontResourceName)
{
    var resourceStream = assembly.GetManifestResourceStream(fontResourceName);
    if (resourceStream == null)
        throw new Exception(string.Format("Unable to find font '{0}' in embedded resources.", fontResourceName));
    var fontBytes = new byte[resourceStream.Length];
    resourceStream.Read(fontBytes, 0, (int)resourceStream.Length);
    resourceStream.Close();
    return fontBytes;
}
