Answer / arun

A compile time error will be thrown as there exist no
methods to override. The methods in the interface are just a
contract.
To override any method, it should be defined as virtual.

Answer / rajeev kumar

1.Method1() and Method2() are not having the ";" for termination .So it is a compile time error.

2.Method must have a return type.So it is a compile time error.

3.Method1() and Method2() must declare a body because it is not marked abstract, extern, or partial .
So it is a compile time error.
It should be like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
interface a
{
void Method1();
void Method2();
}

class b: a
{

public void Method1()
{
Console.WriteLine("From Method1()");
}
public void Method2()
{
Console.WriteLine("From Method2()");
}
}
class Program
{
static void Main(string[] args)
{
b obj=new b();
obj.Method1();
obj.Method2();

}
}
}

Output:
From Method1()
From Method2()

Answer / nithya

It will through the error because
in interface,the methods should have return type for them.
And we can create only implementation for the methods
available in interface. We cannt override it.

And Virtual/Abstarct or not a valid items in interface.

We must implement the methods available in interface.

interface a
{
void Method1();
void Method2();
}
class b: a
{
public void Method1();
public void Method2();
}
