Static Members

Static vs. instance members

We’ve used the static keyword regularly throughout this course, but haven’t really talked about what that means.

Consider the following class:

class Person
{
	public int Age { get; set; }
	public string Name { get; set; }
}

To use this class, we have to create its instance:

var person1 = new Person();
person1.Age = 41;
person1.Name = "John Doe";

var person2 = new Person();
person2.Age = 38;
person2.Age = "Jim Terry";

We now have two instances of the Person class, and each instance has its own copy of the Age ...
