In BaseClass 'i' is local variable, and inside DerivedClass 'i' is again a local variable of it, So, 9 value scope is inside the DerivedClass and 13 scope is outside the DerivedClass, so, to call the base class members we should use "base" keyword console.WriteLine(i+""+base.i);.

But we can't use base keyword under a static block of a derived class.

@Karthi.
They might look the same but please check the format should the output(9 13) be.
In case, you not aware, 'base' refers to the base class/superclass. So if you say 'base.i' you refer to base class.
Hope you answered.

Hi,
Both option A and B are same. May I know what is the difference between them?

@Pavan.
Base is a keyword of c# which is used here to call the I variable of the base class-BaseClass to differ it from the I variable of the derived class-Derived. Whatever, actually it was not necessary to do this if both of the variable were not declared using the same identifier-i.

public static void Main()
{
Derived d=new Derived();
Console.WriteLine("{0} {1}",d.i,d.k);

What is the difference between base.i and mybase.i?

To get output as 9 13,
First you need to get the derived class i value and then you can get the base class i value by object of base class as base.i
Where base is object of BaseClass.

Where is create object name base ?
It is directly used it.
