What is the difference between overriding and overloading in .net

Moeed Moeed 33 4 4 bronze badges. Captain here: Overloading a method gives you multiple signatures of different methods with the same name. Overriding hides an inherited member, either from classes or interfaces. SparK Overriding doesn't hide a member.

You can either override or hide an inherited member. The two are mutually exclusive options. Servy, wrong choice of words, I meant "substitutes".

Here is a comparison table showing similarities between Method Overloading and Method Overriding:. SayHello ; obj. SayHello ; new HelloMale. SayHello ; new HelloFemale. Now, you have two ways to implement this:. This is how payment methods are overloaded in real-world scenarios.

Assume all of them use a common payment gateway except Rupay, which has a payment gateway of its own. Now you would write a parent class that contains the method definition for accepting payments via the common payment gateway. A child class for Rupay would inherit all the parent class features and override just one feature -the payment gateway method. After all, the child class differs only in the payment gateway method.

All other features, such as card number, security token, etc. Thus, we have learned the basic difference between the two most elementary object-oriented programming concepts, Overloading and Overriding. We have written a basic example and understood a real-life business scenario where overloading and overriding can be implemented. Both the concepts are easy to understand theoretically but take practice to implement in practical situations.

More about Static binding and dynamic binding. In method Overloading, two or more methods shares the same name in the same class but having different signature while in method overriding, method of parent class is re-defined in the inherited class having same signature. In the case of performance, method overloading gives better performance when compared to overriding because the binding of overridden methods is being done at runtime.

Static binding is happens when method overloaded while dynamic binding happens when method overriding. Method overloading add or extend more to the method functionality while method overloading is to change the existing functionality of the method.

Static methods can be overloaded, that means a class can have more than one static method of same name. But static methods cannot be overridden, even if you declare a same static method in derived class it has nothing to do with the same method of base class.
