What is difference between Early Binding and Compile time polymorphism?

What is difference between Late Binding and Runtime polymorphism?

What is difference between Runtime Polymorphism and Compile time polymorphism?

hi,

When a message can be processed in different ways is called polymorphism. Polymorphism means many forms.

Polymorphism is one of the fundamental concepts of OOP.

Polymorphism provides following features:
- It allows you to invoke methods of derived class through base class reference during runtime.
- It has the ability for classes to provide different implementations of methods that are called through the same name.
Polymorphism is of two types:
1. Compile time polymorphism/Overloading/early binding
2. Runtime polymorphism/Overriding/Late binding

but what is difference between early binding and compile time polymorphism.

you are saying both are same but have some differences, once that can you explain how can achieve polymorphism without overloading and overridding.

Method overloading is compile time Polymorphism while Method overriding is run time Polymorphism.

It's because function overloads are resolved at the compile time. This is called static or earlier binding(Compiletime Polymorphism)

And virtual methods overrides are resolved at the runtime. This is called dynamic or late binding(Runtime Polymorphism)

Early Binding

The name itself describes that compiler knows about what kind of object it is, what are all the methods and properties it contains. As soon as you declared the object, .NET Intellisense will populate its methods and properties on click of the dot button.

Late Binding

The name itself describes that compiler does not know what kind of object it is, what are all the methods and properties it contains. You have to declare it as an object, later you need get the type of the object, methods that are stored in it. Everything will be known at the run time.
