please give the ans of this question

Hi,

in terms of .NET static keyword is used to declare a property or method of the type which can be directly accessed by Class name means without creating object of the class.

It's faster then a normal property or method because it is a direct pointer to that.

Its value remains same through out the application scope.

Example

public class A

{

public A(){}

public static int Number1=10;

public int Number2=20;

}

public class B

{

public void Func1(A ObjA)

{

MessageBox.Show(Convert.ToString(A.Number1));

MessageBox.Show(Convert.ToString(ObjA.Number2));

A.Number1 = 20;

ObjA.Number2 = 25;

}

}

It is a simple example where Class A contains Number1 as static variable and Number2 as normal variable.

When you invoke Func1 of class B you will get 10 in first message box and 20 in another but when you invoke Func2 of Class C you will get 20 in first Message box and same 20 in another.

Because A.Number1's value is changed in invocation of B.Func1() but A.Number2 remains same because when you create a new instance of A is created which will then re-assign the value of it .

Hope it helps.

Thanks.
