This class is something I distilled from a C library while translating a piece of code that I needed for doing face detection, I ran into this handy class for reading configuration files. Normally you use the ConfigurationManager of .NET to read your app.config files etc..., but this is a handy class to parse files or make very simple flat-files that contain some configuration info.
If you don't want to use XML, then is a very handy utility.
This tokenizer skips comment (#) chars, whitespaces and blank lines.
It also has two properties for knowing when a File ends of when a line ends.
I'm sure that there are other possibilities to do such things, but I find this one easy to use.
