new Modifier (C#)

The new modifier instructs the compiler to use your implementation instead of the base class implementation. Any code that is not referencing your class but the base class will use the base class implementation.

override (C#)

The override modifier may be used on virtual methods and must be used on abstract methods. This indicates for the compiler to use the last defined implementation of a method. Even if the method is called on a reference to the base class it will use the implementation overriding it.

public class A
{
public virtual void One();
public void Two();
}

public class B : A
{
public override void One();
public new void Two();
}

B b = new B();
A a = b as A;

a.One(); // Calls implementation in B
a.Two(); // Calls implementation in A
b.One(); // Calls implementation in B
b.Two(); // Calls implementation in B

"Override" keyword is used for function when we provide different definition to base class function in derived class.

"New" keyword is used for allocate memory to variable.
