Differentiate between overloading and overriding in C#.

Overloading	Overriding
Having same method name with different signatures.	Methods name and signatures must be same.
Overloading is the concept of compile time polymorphism.	Overriding is the concept of runtime polymorphism.
Two functions having same name and return type, but with different type and/or number of arguments is called Overloading.	When a function of base class is re-defined in the derived class called as Overriding.
It doesn't need inheritance.	It needs inheritance.
Method can have different data types.	Method should have same data type.
Method can have different access specifier.	Method should be public.
