C# :: Webrequest And Webresponse Abstract Classes

.Theoretically speaking, we cannot create object of abstract class and even return an instance of it. But according to msdn documentation, WebRequest request = WebRequest.Create("Uri here");. In other word, with this statement, the create method return an instance of the WebRequest class, which is the abstract class.

As far as abstract class is concerned, there is no way for us to return an instance of the derived class within the abstract class or superclass, within the method of abstract class in particular. Since the abstract class knows nothing about the derived class. Unless the method is implemented within the derived class. Here is the statement HttpWebRequest request = (HttpWebRequest) WebRequest.Create("Uri here");
