Can we create the instance for abstract classes

Why can't create object of an abstract class in C# VB.Net

No, you cannot create an instance of an abstract class because it does not have a complete implementation. The purpose of an abstract class is to function as a base for subclasses. It acts like a template, or an empty or partially empty structure, you should extend it and build on it before you can use it.

abstract class MyAbstractClass { } MyAbstractClass obj = new MyAbstractClass(); //not valid

When you try to compile the above code, you will get the Error message like: "Cannot create an instance of the abstract class or interface" .
