我们写exe程序时，默认字体是宋体，比较难看，指定了其他字体，但是其他用户上没有你指定的这个字体的话，也会变成默认的宋体。解决的办法有这么几个：
1，叫用户安装相应字体，这个基本不可能实现，因为没有几个人会进行这样的操作；
2，给用户安装相应字体，这个办法可行，在制作安装包时将字体打包进去，然后用户安装程序的时候连字体也一并安装上去，一劳永逸；
3，把字体导入到程序资源中，让程序直接调用字体资源，缺点是导致程序体积巨大；
4，将字体文件放到程序目录里，在程序里单独调用。
个人觉得第4种办法比较方便，所以决定采用这种方法，把代码写出来给需要的同学。
引用：
Imports System.Drawing.Text
public sub Setfont()
dim AppPath as string = Application.StartupPath
try
dim font1 as PrivateFontCollection = new PrivateFontCollection()
font1.AddFontFile(AppPath + "\font\msyh.ttf") '字体的路径及名字
dim myFont as Font = new Font(font.Families[0].Name, 9,FontStyle.Regular,GraphicsUnit.Point, 134)
'设置窗体控件字体，哪些控件要更改都写到下面
label1.Font = myFont
label2.Font = myFont
label3.Font = myFont
button1.Font = myFont
button2.Font = myFont
button3.Font = myFont
button4.Font = myFont
button5.Font = myFont
catch e as exception
MessageBox.Show("字体不存在或加载失败\n程序将以默认字体显示", "警告",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
end try
然后在public sub Form1()
InitializeComponent()
Setfont() '启动字体设置函数
end sub
在给所有顶层窗口发送消息之前需要在注册表中记录字体：
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
否则是无法显示在系统的字体列表中的。
GDI绘图用字体必须安装才能使用
在客户机部署应用程序时，安装该字体就行
