Understanding Object Lifetime

.NET objects are allocated in a memory called managed heap, where they will be automatically destroyed by the garbage collector.

Before going into details you have to know about the class, object, reference, stack and heap.

A class is nothing but a blueprint that describes how an instance of this type will look and feel in memory. Classes, of course, are defined within a code file (which in C# takes a *.cs extension).

Consider a simple Car class defined in a C# Console Application project named SimpleGC:

    //Car.cs
    public class Car
    {
        private int currSp;
        private string petName;
        public Car() { }
        public Car(string name, int speed)
        {
            petName = name;
            currSp = speed;
        }

        public override string ToString()
        {
            return string.Format("{0} is going {1} MPH",
            petName, currSp);
        }
    }

Once a class is defined, you can allocate any number of objects using the C# new keyword.

Understand, that the new keyword returns a reference to the
