inheritance in c#

// Parent Class
public class A
{
    public void Method1()
    {
        // Method implementation.
    }
}
// inherit class A in class B , which makes B the child class of A
public class B : A
{ }

public class Example
{
    public static void Main()
    {
        B b = new B();
        // It will call the parent class method 
        b.Method1();
    }
}//example

class derived: super
{private int arg;
// constructor
public derived(int arg, int super_arg): base(super_arg)
{
this.arg=arg;
this.super_arg=super_arg;
}
}
