Hi Vamshi Both the methods are doing same operations. rather than using different method name to perform same operation you can use the same method name and pass different number of parameters. It is the easy way of programming. For demo please see https://dotnetfiddle.net/WGYhfk Thanks Sandeep

Hi Well one obvious advantage I can think of is that you don't have to think for a name for every method just remember one method name for exp: i have a sendmail method like this public void sendmail (body to from) { } public void sendmail(bodytofromattachment) { } public void sendmail(bodtofromattachmentcc) { } so here is 3 method with same name you just have to pass different signs even you just hv to remember one method name but just think if i gave different name of every method from that you have to remember at least 3 method name so what is more easy 1 method name or 3 method name.I think you get the point Basically what it does here is improve consistency and readability. 1)Overloading has nothing to do with OOP ever. 2) It's good to understand that overloading is just a bad term because nothing is actually loaded; the sensible explanation of the term is merely having methods of different signatures using the same name.

Hi  Method overloading Provides You same Method with Different Signature(Signature means No Of parameter type of parameter and order of parameter). Just Like In Your Example You created Add Method that is taking 2 and 3 parameter. By taking same name programmer should not to worry about remembering method name. Depend on your parameter that overloaded method will call.

Hi Vamsi I hope you good in OOPs class design. Why we go for class? we wanna do some task or set of tasks but that task should be well organised. So we used lot's techniques like OOPs SOLID Patterns Frameworks etc... Polymorphism is the technique we can do different behaviour to the same interface in by using different context.
