.NET interview questions: -Describe operator overloading?

Operator overloading is a concept of polymorphism where you can redefine operators like +, - , * etc with additional functionalities.

For instance we can redefine the + functionalities to add objects like obj1 + obj2. Below is simple code snippet which redefines + operator.

class SomeClassprivate int someValue;public SomeClass(int val)someValue = val; }public static SomeClass operator +(SomeClass arg1, SomeClass arg2)return new SomeClass(arg1.someValue + arg2.someValue);}}

You can now use the + operator to add objects of type someclass as shown in the below code snippet.

Obj = obj1 = obj2;
