(n.)A boundary across which two independent systems meet and act on or communicate with each other. In computer technology, there are several types of interfaces. user interface - the keyboard, mouse, menus of a computer system. The user interface allows the user to communicate with the operating system.
What is an interface in Java?
A Java interface is a bit like a class, except a Java interface can only contain method signatures and fields. An Java interface cannot contain an implementation of the methods, only the signature (name, parameters and exceptions) of the method. You can use interfaces inJava as a way to achieve polymorphism.

Vedant,
Its known that Interface cannot be instantiated, what I suggest you that check the DLL in object explorer and for sure some class is included in that implements this interface.

Then you need to instantiate that class and use those methods of interface. For example

IProducts is interface with GetProducts and AddProducts method declaration of your DLL, the ProductService is class implementation of IProducts interface. You can use this kind of code

IProducts prod = new ProductService();
prod.GetProducts();
prod.AddProducts();

Accept if it works for you

Hi

1)Add the DLL as reference
2) Implement the Interfce

Class A :Interface
{
//Implement here your methods
}
