In [[C Sharp Variables and Constants|C# Variables and Constants]] we looked at using variables and constants in C# and also described the different variable and constant types. Being able to create constants and variables is only part of the story however. The next step is to learn how to use these variables and constants in C# code. The primary method for working with the data stored in constants and variables is in the form of ''expressions''. In this chapter we will look in detail at C# expressions and operators.
