Interface IN Csharpdotnet

I used to play with interfaces :) . Interfaces are implicit by default. You use explicit interface if you want to implement two interfaces with the same signatures.

If you want to Paint both Wall and Gate, below code explains implicit and explicit way of Paint() method implementation.

Implicit(Default) -

public class DoPainting : IGate, IWall
{
public void Paint()
{
Console.WriteLine("What I need to paint?");
}
}
interface IGate
{
void Paint();
}
interface IWall
{
void Paint();
}

Only one method for both interface. But most cases and design perspective, this should be separated and so using explicit interface. See below.

Explicit (Mention interface name with Method)-

public class DoPainting : IGate, IWall
{
void IGate.Paint()
{
Console.WriteLine("DO gate paint");
}
void IWall.Paint()
{
Console.WriteLine("DO wall paint");
}
}
interface IGate
{
void Paint();
}
interface IWall
{
void Paint();
}

Also notice that the access modifier of the methods are removed. This is the correct way on design perspective.
