Method Overloading:
Method Overloading is the common way of implementing polymorphism. It is the ability to redefine a function in more than one form. A user can implement function overloading by defining two or more functions in a class sharing the same name

Method Overloading:

Method overloading allows programmers to use multiple methods with the same name. The methods are differentiated with their number and type of method arguments. Method overloading is an example of the polymorphism feature of an object oriented programming language.

Method overloading can be achieved by the following:
By changing number of parameters in a method

By changing the order of parameters in a method

By using different data types for parameters

Hi Jay,

Overloading is used in programming languages that enforce type-checking in function calls during compilation. When a method is overloaded, the method chosen will be selected at compile time. This is not the same as virtual functions where the method is defined at runtime.

Unlike Java, C# allows operators to be overloaded, in addition to methods, by defining static members using the operator keyword. This feature helps to extend and customize the semantics of operators relevant to user-defined types so that they can be used to manipulate object instances with operators.

The overload resolution in C# is the method by which the right function is selected on the basis of arguments passed and the list of candidate function members that have the same name. The different contexts in which the overload resolution is used include:
- Invocation of a method in an expression
- Constructor during object creation
- Indexer accessor through element access and predefined or user-defined operator expression
It is recommended to avoid overloading across inheritance boundaries because it can cause confusion. Overloading can become cumbersome to developers if it is used excessively and with user-defined types as parameters because it can reduce the readability and maintainability of code.

Hi,

These are basics of OOPS concepts, In Polymorphism we have 2 different types of binding.
Overloading (Called as Early Binding or Compile Time Polymorphism or static binding)
Overriding (Called as Late Binding or Run Time Polymorphism or dynamic binding)
Overloading :

The methods with same name but different signatures because of this we will perform different tasks with same method name. This overloading also called as compile time polymorphism or early binding.

Overloading lets you define the same method multiple times so that you can call them with different argument lists (a method's argument list is called its signature).
