Read only and write only property

In this chapter you will learn:

  1. How to create read only or write only property in C#
  2. Combine readonly and read only property

Read only property

If a property has only get accessor we call it read-only property. The following code add read-only area property to the Rectangle.

using System;/*from   ja  va 2 s.com*/
class Rectangle
{
    public int Width;
    public int Height;

    public int Area
    {
        get
        {
            return Width * Height;
        }
    }
}


class Program
{
    static void Main(string[] args)
    {
        Rectangle r = new Rectangle();
        r.Width = 5;
        r.Height = 6;
        Console.WriteLine(r.Area);


    }
}

The output:

Combine readonly and read only property

using System;/*from   j  av  a2 s . c o m*/

public sealed class Value
{
    public int intValue = 10;
}

public sealed class MyController
{
    public MyController( Value pimpl ) {
        this.pimpl = pimpl;
    }

    public int IntValue {
        get {
            return pimpl.intValue;
        }
    }

    private readonly Value pimpl;
}

public sealed class MainClass
{
    static void Main() {
        Value someNumber = new Value( );
    }
}
