How to Debug C# Programs #1: NullReferenceException, Histacom BIOS mock-up
Hey guys! I'm going to be starting a bit of a mini-series where I show you guys how to debug and fix C# programs and the various crashes you'll get when something goes wrong.
What better thing to start off with than a NullReferenceException in the code of a Packard Bell BIOS mock-up by my friend Richie? This one is a simple one, but it'll show you how I use the call stack and Locals window to find out where in the .NET Framework the exception was thrown and what variable reference was null. Based on those findings, I can very easily figure out what the actual bug is.
In this case, an attempt was made to set the Font property of an uninitialized Label variable.
