.NET System.Drawing.Font - Get Available Sizes and Styles

问题

I have one combo that allows user to select a font name.

The 2nd is supposed to show available sizes of the font. The 3rd has to show available styles.

Question: how can I retrieve the sizes and styles selected System.Drawing.Font supports?

回答1:

You could use the InstalledFontCollection class to retrieve the available fonts and then enumerate them as shown in this MSDN article.

InstalledFontCollection installedFontCollection = new InstalledFontCollection();

// Get the array of FontFamily objects.
fontFamilies = installedFontCollection.Families;

// The loop below creates a large string that is a comma-separated
// list of all font family names.

int count = fontFamilies.Length;
for (int j = 0; j < count; ++j)
{
    familyName = fontFamilies[j].Name;
    familyList = familyList + familyName;
    familyList = familyList + ",  ";
}

I was trying to find a good-looking font family today, I use the below code to enumerate all font families, and print them in an image, so that it is easier to compare which looks good.

Shared below:

        Bitmap bitmapImage = new Bitmap(width: 1600, height: 8000);
        using (Graphics g = Graphics.FromImage(bitmapImage))
        {
            var imageRect = new Rectangle(x: 0, y: 0, width: 1600, height: 8000);

            System.Drawing.Text.InstalledFontCollection installedFontCollection = new System.Drawing.Text.InstalledFontCollection();
            FontFamily[] fontFamilies = installedFontCollection.Families;

            var format = new StringFormat();
            format.Alignment = StringAlignment.Near;
            format.LineAlignment = StringAlignment.Near;
            format.FormatFlags = StringFormatFlags.NoWrap;

            int verticalOffset = 0;
            for (int j = 0; j < fontFamilies.Length; ++j)
            {
                using (var font = new Font(fontFamilies[j].Name, 40, FontStyle.Regular, GraphicsUnit.Pixel))
                {
                    // Height
                    var textSize = g.MeasureString(fontFamilies[j].Name, font);
                    int textWidth = (int)Math.Ceiling(textSize.Width + 10);
                    int textHeight = (int)Math.Ceiling(textSize.Height + 10);

                    // Draw text
                    Rectangle textRect = new Rectangle(x: j % 2 == 0 ? 0 : 800, y: verticalOffset, width: textWidth, height: textHeight);
                    g.FillRectangle(new SolidBrush(BackgroundColor), textRect);
                    g.DrawString(fontFamilies[j].Name, font, new SolidBrush(PercentageTextColor), textRect, format);
                    g.Save();

                    if (j % 2 == 1)
                    {
                        verticalOffset += textHeight;
                    }
                }
            }
        }

        bitmapImage.Save(this.Response.OutputStream, ImageFormat.Png);


        // then do whatever you like with this bitmapImage, save it to local, etc.
