+>>As far as I know we can't instantiate an abstract class.. so what is it for?
+>>You can't instantiate the class, right?
+>Because there might be a standard way you want to instantiate data in the abstract class. That way you can have classes that inherit from that class call the base constructor.

+public abstract class A{

+      data = myString;

+}
+public class B : A {
+     B(string myString) : base(myString){}
