Edit Question
Title
Body
What are all the difference between an abstract class, and a class with only protected constructor(s)? They seem to be pretty similar to me, in that you can't instantiate either one. EDIT: How would you create an instance in a derived class, with a base class with a protected constructor? For instance: public class ProtectedConstructor { protected ProtectedConstructor() { } public static ProtectedConstructor GetInstance() { return new ProtectedConstructor(); // this is fine } } public class DerivedClass : ProtectedConstructor { public void createInstance() { ProtectedConstructor p = new ProtectedConstructor(); // doesn't compile } public static ProtectedConstructor getInstance() { return new ProtectedConstructor(); // doesn't compile } }
