示例1: HighlightACharacterRange
private void HighlightACharacterRange(PaintEventArgs e)
{
// Declare the string to draw.
string message = "This is the string to highlight a word in.";
// Declare the word to highlight.
string searchWord = "string";
// Create a CharacterRange array with the searchWord
// location and length.
CharacterRange[] ranges =
new CharacterRange[]{new CharacterRange
(message.IndexOf(searchWord), searchWord.Length)};
// Construct a StringFormat object.
StringFormat stringFormat1 = new StringFormat();
// Set the ranges on the StringFormat object.
stringFormat1.SetMeasurableCharacterRanges(ranges);
// Declare the font to write the message in.
Font largeFont = new Font(FontFamily.GenericSansSerif, 16.0F,
GraphicsUnit.Pixel);
// Construct a new Rectangle.
Rectangle displayRectangle = new Rectangle(20, 20, 200, 100);
// Convert the Rectangle to a RectangleF.
RectangleF displayRectangleF = (RectangleF)displayRectangle;
// Get the Region to highlight by calling the
// MeasureCharacterRanges method.
Region[] charRegion = e.Graphics.MeasureCharacterRanges(message,
largeFont, displayRectangleF, stringFormat1);
// Draw the message string on the form.
e.Graphics.DrawString(message, largeFont, Brushes.Blue,
displayRectangleF);
// Fill in the region using a semi-transparent color.
e.Graphics.FillRegion(new SolidBrush(Color.FromArgb(50, Color.Fuchsia)),
charRegion[0]);
largeFont.Dispose();
