static method problem

Static methods know nothing about instances of the same class or its ancestor class(es).

They only know about other 'accessible' static members of those classes.

So, if you want them to do something with an instance, you need to provide them with a reference to that instance.

One way of doing that is to create an instance within the static method itself as you're doing with this code:

class b:a

{

public void xyz()

{

SqlConnection con = getcon();

// blah

}

public static xys()

{

a obj = new a();

SqlConnection con = obj.getcon();

// blah

}
