A class is a template used to create objects. They are made up of members, the main two of which are fields and methods. Fields are variables that hold the state of the object, while methods define what the object can do.
class Rectangle
{
int x, y;
int GetArea() { return x * y; }
}

To use a class’s instance members from outside the defining class, an object of the class must first be created. This is done by using the new keyword, which will create a new object in the system’s memory.
class MyApp
{
static void Main() ...
