如何使用C#安装Windows字体

Question

如何使用C#安装字体？

我尝试使用复制字体,File.Copy()但由于访问权限限制,我不被允许(UnauthorizedException).

我该怎么办？

您需要一种不同的方法来安装字体.

• 使用安装程序(创建安装项目)来安装字体
• 使用本机方法的另一种(更简单)方法.

声明dll导入:

    [DllImport("gdi32.dll", EntryPoint="AddFontResourceW", SetLastError=true)]
    public static extern int AddFontResource(
        [In][MarshalAs(UnmanagedType.LPWStr)]
        string lpFileName);

在你的代码中:

    // Try install the font.
    result = AddFontResource(@"C:\MY_FONT_LOCATION\MY_NEW_FONT.TTF");
    error = Marshal.GetLastWin32Error();

我把它放在一个单元测试中,我希望有帮助:

[TestFixture]
public class Tests
{
    // Declaring a dll import is nothing more than copy/pasting the next method declaration in your code. 
    // You can call the method from your own code, that way you can call native 
    // methods, in this case, install a font into windows.
    [DllImport("gdi32.dll", EntryPoint = "AddFontResourceW", SetLastError = true)]
    public static extern int AddFontResource([In][MarshalAs(UnmanagedType.LPWStr)]
                                     string lpFileName);

    // This is a unit test sample, which just executes the native method and shows
    // you how to handle the result and get a potential error.
    [Test]
    public void InstallFont()
    {
        // Try install the font.
        var result = AddFontResource(@"C:\MY_FONT_LOCATION\MY_NEW_FONT.TTF");
        var error = Marshal.GetLastWin32Error();
        if (error != 0)
        {
            Console.WriteLine(new Win32Exception(error).Message);
        }
    }
}

这应该会帮助你的方式:)
