C# .NET - interface implementation in c# web application

Interface is a pure abstract entity:

• It contains only the declaration.
• We cannot make instance of an Interface. We must inherit to use Interface.
• A class which implements the interface should implement all the members of an Interface.
• Members of an Interface are always public.

Example of Interface

interface ISampleInterface1
{
    void SampleMethod1();
}


interface ISampleInterface2
{
void SampleMethod2();
}
 
class ImplementationClass : ISampleInterface1, ISampleInterface2
{
    // Explicit interface member implementation:
    void ISampleInterface1.SampleMethod1() { // Method implementation.
    void ISampleInterface2.SampleMethod2() { // Method implementation.

   }

    static void Main()
    {
    // Declare an interface instance.
    ISampleInterface1 obj = new ImplementationClass();

    // Call the member.
    obj.SampleMethod1();
    }
}

 
In this way you can be able to implement the Interface for the Inheritance
