Can abstract class have constructor?

Question

Can abstract class have constructor? if yes? then we know that we can't create the object of class then how do we use that?

Yes We can create constructor for abstract class. But We cannot create object and access that. The Abstract class will be inherited for a normal class when the object created for normal class the abstract calss constructor will be called. Eg: abstract class Class1 { public Class1() { } public abstract void aa(); } class Program : Class1 { static void Main(string[] args) { Program p = new Program(); p.aa(); } } Here when Program p is initilized the abstract class ctor will be called. Hope this correct.
