What really is the purpose of “base” keyword in c#?

Question

Thus for used base class for some commom reusable methods in every page of my application...

public class BaseClass:System.Web.UI.Page
{
   public string Get         


        

Answer 1

The base keyword is used to access members in the base class that have been overridden (or hidden) by members in the subclass.

For example:

public class Foo
{
    public virtual void Baz()
    {
        Console.WriteLine("Foo.Baz");
    }
}

public class Bar : Foo
{
    public override void Baz()
    {
        Console.WriteLine("Bar.Baz");
    }

    public override void Test()
    {
        base.Baz();
        Baz();
    }
}

Calling Bar.Test would then output:

Foo.Baz;
Bar.Baz;
