C# Can a base class property be invoked from derived class

Question

I have a base class with a property which has a setter method. Is there a way to invoke the setter in the base class from a derived class and add some more functionality to it just like we do with overriden methods using the base keyword.

Sorry I should have added an example. Here is an example. Hope I get it right:

public class A 
{
    public abstract void AProperty 
    {
        set 
        {
            // doing something here
        }
    }
}

public class B : A 
{   
    public override void AProperty 
    {
        set 
        {
            // how to invoke the base class setter here

            // then add some more stuff here
        }
    }   
}

Solution

EDIT: the revised example should demostrate the order of invocations. Compile as a console application.

class baseTest 
{
    private string _t = string.Empty;
    public virtual string t {
        get{return _t;}
        set
        {
            Console.WriteLine("I'm in base");
            _t=value;
        }
    }
}

class derived : baseTest
{
    public override string t {
        get { return base.t; }
        set 
        {
            Console.WriteLine("I'm in derived");
            base.t = value;  // this assignment is invoking the base setter
        }
    }
}

class Program
{

    public static void Main(string[] args)
    {
        var tst2 = new derived();
        tst2.t ="d"; 
        // OUTPUT:
        // I'm in derived
        // I'm in base
    }
}

Have you actually tried to call base yourself?

[Adam Crossland]

All your base are belong to you. Of course you can do this. You can use base inside a setter.

[Vadim]

can you provide an example of what you'd like to do?

[Paolo Falabella]

your setter in the base class should be virtual instead of abstract if you want to have code in place of your comment "doing something here"

[Shahid]

@paolo ok lets say I have it as virtual. my question still remains how do I invoke that code with a single call rather than having to re-write it in the derived setter or putting it in another protected method and calling it

[Paolo Falabella]

@Shahid maybe I'm being dense and I don't understand your objection... When you assign to base.t in the derived class you are actually using the setter in the base class, so if you have more logic inside the base setter it will indeed be invoked

[Paolo Falabella]

@Shahid I changed my example a little to show that indeed the base setter is called when you assign a value to the inherited property

[Shahid]

You are not actually invoking what the setter in the base class property 't' is doing. If the base setter 't' had 10 lines of code, can we call it from the derived class so those 10 lines of code are executed and then we add additional lines of code

[Paolo Falabella]

@Shahid yes I am. Try changing the code in the base class setter to set { Console.WriteLine("I'm in base"); _t=value;} and see for yourself.

[Shahid]

Thanks paolo. I have been stupid to overlook this. I accepted your answer now

[Paolo Falabella]

@Shahid no worries, I'm not a native english speaker and I really thought I wasn't understanding what you needed to do... Glad I've been of help
