why we are using method overloading?

Hi,

 

Overloading is the process of defining a number of methods with the same name and return type, but which has different parameters. Method overloads are best used when the same operation can be done in several different ways, depending on parameters - for example sorting. An overload with no parameters may apply a default sort. An overload with a sort order will allow sort order, and another one may have a Func delegate that determines the sort algorithm.
