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()
