I am using pixels as the unit for my font. In one place, I am performing a hit test to check if the user has clicked within the bounding rectangle of some text on screen. I need to use something like MeasureString for this. Unfortunately, the code doing the hit test is deep within a library which does not have access to a Graphics object or even a Control.

How do I get the bounding box of a string given the font without using the Graphics class? Why do I even need a Graphics object when my font is in pixels?

If you have a reference to System.Windows.Forms, try using the TextRenderer class. There is a static method (MeasureText) which takes the string and font and returns the size. MSDN Link
