    Re: what is an interface

    Hi Prakashraj,

    An interface contains only the signatures of methods, delegates or events. The implementation of the methods is done in the class that implements the interface, as shown in the following example:

    interface ISampleInterface
    void SampleMethod();

    class ImplementationClass : ISampleInterface
    // Explicit interface member implementation:
    void ISampleInterface.SampleMethod()
    // Method implementation.

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

    // Call the member.

    Thanks & Regards,
