Inheritance in C#

I have an abstract class called 'BasePage'.
And many other classes inherit from this class.
For example, LoginPage class inherit from 'BasePage' class.

class LoginPage:BasePage{
...
}
class EmployeePage:BasePage{
...
}

Open in new window


And BasePage class inherits from 'Base' class.
And Base class has a property of 'BasePage' type.
I don't understand what this is good for.

Why don't we add CurrentPage property into 'BasePage' class?
Can you explain the intention of adding 'BasePage' type property to 'Base' class and 'BasePage' inherits from 'Base' class?
public class Base
{
        public BasePage CurrentPage { get; set; }
 }

Open in new window


Then, in a UnitTest1 class, it is used as follow:
  public class UnitTest1 : Base
    {
        string url = "http://localhost";        


        [TestMethod]
        public void TestMethod1()
        {        
            .....    
            LoginPage page = new LoginPage();
            ......
            CurrentPage = page.ClickEmployeeList();            
            ((EmployeePage)CurrentPage).ClickCreateNew();
        }
    }

Why it is done this way you would have to ask the original designer/coder.  Everything else is just a guess.

>>Why don't we add CurrentPage property into 'BasePage' class?
Very good question.  The current layout looks rather strange to me with the base class having to 'know' about a derived class for it to function.

Just a wild guess:

It's kind of a context concept. So that you don't have to call a different objects to get the current page.
