§ The NET Framework Class Library (FCL) can be used by any NET language

Object Model

§ Object ==> Like a Noun in English

ŸForm and Controls on forms ( Button, Text boxes …)

§ Property ==> Like Adjective,they describe object

ŸText, Name, BackColor, Font and Size

§ Method ==> Like Verb, They are actions that objects exhibit

§ Event ==> Occur when the user takes action

ŸUser clicks a button

§ Class ==> Template to create new object

ŸEach control added is an Instance of a Class (Example: adding a second form to the project – it will have the same properties)

Dot Notation

§Used to reference object's properties and methods in code

ŸObject dot Property

Form.Text, TextBox.Text

(Example: lblMessage.Text = "Hello World“)

ŸObject dot Method

Form.Hide( ), TextBox.Focus( )

§To reference an object's events use an underscore instead of a dot Button_Click, ListBox_TextChanged

private void btnHoLot_Click(object sender, EventArgs e)

{

// statement

}

INTRODUCTION

§ C#.NET supports programming projects that run in both

Windows desktop and Internet environments We will focus on the Windows desktop

§ Both of these environments are based on what is termed a

graphical user interface or GUI for short

Steps for Writing C#
