Method Overloading

Understand method overloading by defining multiple methods with the same name but unique signatures to handle different parameter types, quantities, and modifiers.

We often require methods that execute similar logic but accept different parameter types or quantities. Consider a Multiply() method designed for two operands. If the requirements expand to support three operands, we use overloading to maintain a consistent API.

Method signature

In C#, we can create several methods that have the same name but differ in other portions of their signature. A method signature consists of several parts:

  • Method name

  • Parameter quantities

  • Parameter types

  • Parameter order

  • Parameter modifiers

Note: Parameter names and the method return type are not part of the method signature.

Method overloading creates several methods that have the same name but differ in any other parts of the signature.
