Abstract with real time Example

Abstract methods implementation and non-implementation method like

Abstract classes are similar to interfaces. You cannot instantiate them, and they may contain a mix of methods declared with or without an implementation. However, with abstract classes, you can declare fields that are not static and final, and define public, protected, and private concrete methods.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConsoleApplication1

{

//Abstart methods implemetation and non implemetation method like

//abstract Class

public abstract class AbstractClass

{

public abstract void salary();

public void GetEmpName()

{

Console.WriteLine("Naresh");

}

}

//derived class

public class FresherSalary : AbstractClass //inheriting from abstract class

{

public override void salary()

{

Console.WriteLine("Fresher Salary = 10000");

}

}

public class ExpSalary : AbstractClass //inherting from abstract class

{

public override void salary()

{

Console.WriteLine("Exp salary = 20000");

//Console.ReadLine();

}

}

internal class Program

{

public static void Main(string[] args)

{

FresherSalary fresher = new FresherSalary(); //Creating object for fresher

fresher.salary();

ExpSalary exp = new ExpSalary();

exp.salary();

//and calling implemented method in abstart class

exp.GetEmpName();

Console.ReadLine();

}

}

}
