This is one of my favorite coding method. If used properly, it can make your coding life much easier. Using "this", you can create a static method. For example, if you frequently use code to convert from byte type to file type, you can create your own static method for the byte type, called "ToFile()". Then you will just call the method by adding ".ToFile()" at the end of a byte type variable. I..
