C# > Interfaces

In this section we shall learn about interfaces.

Interfaces:

• An interface is similar to class but it provides a specification rather than the implementation for its members. An interface is special in the following ways.
• Interface members are implicitly abstract, In constrast, a class can provide both abstract members concrete members with implementation.
•  A class can implement multiple interfaces. In contrast, a class can inherit from only a single class and struct can not inherit at all

The declaration of the interfaces

Interfaces are declared using interface keyword. Interface keywords are public by default

interface IExample
{
    void SampleMethod();
}

In the above code snippet we have declared the interface. We have defined the interface as Iexample  and we have defined the interface as voidSamplemethod() .

There  are different types of interfaces they are 

• Multiple interfaces 
• Explicit interfaces
• Virtual interfaces
