Abstract Class

Accepted answer

If you don't provide an abstract class with a constructor, then the system provides it with a protected parameterless constructor by default which does nothing except call its base class's parameterless constructor.

Note that even if you provide an abstract class with a public or internal constructor, you still can't create an instance of it for obvious reasons.

Something like below is possible.. googling gave me below answer..

It provide a standard way 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
{
private string data;
protected A(string myString)
{
data = myString;
}
}

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

}
