Private instance data members - accessors
Microsoft has stared calling private variables with accessors Properties
Private class memebers the use get and set keyword to set and retrieve data. Get and set are known as accessor methods private members are helpful when you want to also do other things when a data member is changed or change the rutern value under certain conditions. C# Programmer's Reference - Accessors http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vclrfaccessorspg.asp. Lastly accessor also make read only and write only variables possible
<csharp>//private string color read/write
private string color;
public string Color
{
get
{
return color;
}
set
{
color = value;
}
}
//private string color read only
private string color;
public string Color
{
get
{
return color;
}
}</csharp>
Another property that is a good candidate for a private instance data member is the dogs age
<csharp>
private string age;
public int Age
{
//age can only be accessed with get there is no set accessor
//age must be set with HappyBirthday()
get
{
return age;
}
}
public int HappyBirthday()
{
age++;
return age;
}
</csharp>
Windows forms
Events
- events from a windows form or web page are handled by event handlers. Events are raised when a user interacts with interface elements and handled by the event handlers.
http://www.csharphelp.com/archives/archive253.html
Examaple of event handlers and classes
http://iam.colum.edu/oop/MotorvehicleRace.zip
<csharp>
private void button1_Click(object sender, EventArgs e)
{
Console.WriteLine("button1 Clicked");
MessageBox.Show("button1 Clicked");
}
</csharp>
Create a windows form with a button the uses your class.
<csharp>
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace WindowsDog
{
public partial class Form1 : Form
{
Dog fido;
public Form1()
{
InitializeComponent();
fido = new Dog();
}
private void btnBark_Click(object sender, EventArgs e)
{
lblBark.Text = fido.Bark();
}
public class Dog
{
public string Name; // the dog's name
public int Age; // the dog's age
public int Weight; // the dog's weight
public string BarkSound; // the sound of the dog's bark
public Dog()
{
BarkSound = "Woof!!!";
}
public string Bark()
{
return this.BarkSound;
}
public void Eat()
{
//put eat code here
}
}
}
}
</csharp>
Home Work
Put your class in a windows form. Use and event to call one of your methods.
