如何使用未在C＃中安装的字体的Graphics.DrawString

Question

环境：Windows 7专业版，C＃，WinForms

如果安装了字体，我成功使用Drawstring将文本字符串写入PictureBox。 ＆lt; ==以下代码工作得很好......

我还希望能够从文件系统动态加载的字体文件中编写文本字符串（也就是说，未安装） ＆lt; ==下面的代码不工作...... < / EM>

理想情况下，我想支持TrueType和OpenType。

谢谢， 杰森

PointF pointF = new PointF(5, 5);
SolidBrush solidBrush = new SolidBrush(Color.Black);

FontFamily[] fontFamilies;
PrivateFontCollection privateFontCollection = new PrivateFontCollection();

// Add the font file to the private collection.
try
{
    privateFontCollection.AddFontFile(FontFileName);
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    throw;
}

fontFamilies = privateFontCollection.Families;

e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
e.Graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
e.Graphics.TextRenderingHint = TextRenderingHint.AntiAlias;

FontStyle[] fontStyles = { FontStyle.Regular, FontStyle.Bold, FontStyle.Italic, FontStyle.Bold | FontStyle.Italic,
                             FontStyle.Underline, FontStyle.Strikeout };

foreach (FontFamily fontFamily in fontFamilies)
{
    foreach (FontStyle fontStyle in fontStyles)
    {
        if (fontFamily.IsStyleAvailable(fontStyle))
        {
            Font font = new Font(fontFamily.Name, NewFontSize, fontStyle, GraphicsUnit.Pixel);

//＆lt;＆lt; “font”加载为MS Sans Serif，如果未安装Font＆gt;＆gt;

            Size fontDisplayDimensions = TextRenderer.MeasureText(SampleText, font);


            // Draw sample text in font
            e.Graphics.DrawString(SampleText, font, solidBrush, pointF);

            // Move the starting point for the next FontFamily "down" for the just drawn font's height 
            pointF.Y += font.Height;
        }
    }

    // Separate the families with white space.
    pointF.Y += 10;
}
