测试是否安装了Font

Question

是否有一种简单的方法(在.Net中)来测试当前机器上是否安装了Font？

Answer 1

string fontName = "Consolas";
float fontSize = 12;

using (Font fontTester = new Font( 
       fontName, 
       fontSize, 
       FontStyle.Regular, 
       GraphicsUnit.Pixel)) 
{
    if (fontTester.Name == fontName)
    {
        // Font exists
    }
    else
    {
        // Font doesn't exist
    }
}

Answer 2

如何获得所有已安装字体的列表？

var fontsCollection = new InstalledFontCollection();
foreach (var fontFamily in fontsCollection.Families)
{
    if (fontFamily.Name == fontName) {...} \\ check if font is installed
}

有关详细信息,请参阅InstalledFontCollection类.

Answer 3

感谢Jeff,我最好阅读Font类的文档:

如果familyName参数指定运行应用程序的计算机上未安装的字体或不受支持,则将替换Microsoft Sans Serif.

这些知识的结果:

    private bool IsFontInstalled(string fontName) {
        using (var testFont = new Font(fontName, 8)) {
            return 0 == string.Compare(
              fontName,
              testFont.Name,
              StringComparison.InvariantCultureIgnoreCase);
        }
    }

使用Font创建建议的其他答案仅在FontStyle.Regular可用时才有效.某些字体,例如Verlag Bold,没有常规样式.创建将失败,但Font'Verlag Bold'不支持样式'Regular'.您需要检查应用程序所需的样式.解决方案如下:

  public static bool IsFontInstalled(string fontName)
  {
     bool installed = IsFontInstalled(fontName, FontStyle.Regular);
     if (!installed) { installed = IsFontInstalled(fontName, FontStyle.Bold); }
     if (!installed) { installed = IsFontInstalled(fontName, FontStyle.Italic); }

     return installed;
  }

  public static bool IsFontInstalled(string fontName, FontStyle style)
  {
     bool installed = false;
     const float emSize = 8.0f;

     try
     {
        using (var testFont = new Font(fontName, emSize, style))
        {
           installed = (0 == string.Compare(fontName, testFont.Name, StringComparison.InvariantCultureIgnoreCase));
        }
     }
     catch
     {
     }

     return installed;
  }
