Searching for: Class and Instance Variables in C#
Used to declare a variable. Variables can be implicitly or explicitly typed. Variables declared this way (without a static modifier) within classes are called instance variables. They belong to an instance of the class (i.e. an object).
Static methods are methods that are called on the class itself, not on a specific object instance. The static modifier ensures implementation is the same across all class instances. In other languages, these are known as 'class methods'.
