Obtaining the Width in Pixels of any given character

I have this really awesome idea, but cannot find out if there are any classes in the .NET Framework (any version, preferrably 3.5 or 4.0) that allow you to pass in a character, and get back the width in pixels of that character, no matter which font, or font size or font-decoration is being used. Can someone please point me in the right direction? Does a class/something even exist for something like this?

If WPF works for you (I see someone just removed the WPF tag for this question, but it was there originally) there is also FormattedText:

FormattedText formattedText = new FormattedText("hello foo",
                                                CultureInfo.GetCultureInfo("en-us"),
                                                FlowDirection.LeftToRight,
                                                new Typeface("Arial"),
                                                FontSize = 14,
                                                Brushes.Black);
double width = formattedText.Width;

Check out the Graphics.MeasureString method.

Code sample adapted from the link:

SizeF charSize = e.Graphics.MeasureString("X", new Font("Arial", 16));
// do stuff with charSize ...

The sample above assumes you're in the function body of a Paint event handler and the Graphics object is already created for you and passed in as an event parameter. If you don't want or can't do it in a Paint handler you can create a graphics object at your convenience with Control.CreateGraphics.
