Nik*_*nde 30 c# fonts embedding
这可能是noob领域,但是到底是什么:
我想在winforms应用程序中嵌入字体,这样我就不用担心它们会被安装在机器上.我在MSDN网站上搜索了一下,发现了一些关于使用本机Windows API调用的提示,例如由Scott Hanselman链接的Michael Caplans(sp?)教程.现在,我真的必须经历所有麻烦吗?我不能只使用我的应用程序的资源部分吗?
如果不是,我可能会去安装路线.在那种情况下,我可以通过编程方式进行吗?只需将字体文件复制到Windows\Fonts文件夹即可?
编辑:我知道许可问题,感谢关注.

这在VS 2013中对我有用,而不必使用不安全的块.
嵌入资源
将字体加载到内存中
添加using System.Drawing.Text;到您的Form1.cs文件
在默认构造函数的上方和内部添加代码以在内存中创建字体(不使用"unsafe",如其他示例所示).下面是我的整个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);
}
}
}

在主窗体中添加标签,并添加一个load事件来设置Form1.cs中的字体:
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);

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

我将随机下载的字体拖放到我的资源中,这奏效了。虽然使用文件。我猜你也可以用它来安装字体?
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);
}
