Introduction
§Visual Studio .NET
Ÿ Framework.
Ÿ Microsoft’s Integrated Development Environment
(IDE)
16
The .NET Framework
§ The Common Language Runtime (CLR) is another
central part of the .NET Frameworkitexecutes .NET
programs
§ The .NET Framework Class Library (FCL) can be
used by any .NET language.

Programming Languages
§ Procedural
Ÿ Program specifies exact sequence
§ Event Driven
§ Object Oriented Programming (C#.NET)
Ÿ User controls sequence

Object Model
§ Object ==> Like a Noun in English
Ÿ Form and Controls on forms (Button, Text boxes…)
§ Property ==> Like Adjective,theydescribe object
Ÿ Text, Name, BackColor, Font and Size
§ Method ==> Like Verb, They are actions that objects exhibit
§ Event ==> Occur when the user takes action
Ÿ User clicks a button
§ Class ==> Template to create new object
Ÿ Each control added is an Instance of a Class (Example: adding a
second form to the project –it will have the same properties)
22
Dot Notation
§ Used to reference object's properties and methods in code
Ÿ Object dot Property
Form.Text, TextBox.Text
(Example: lblMessage.Text = "Hello World“)
Ÿ Object 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
}
23
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
24
Steps for Writing C#
§ Design/Define the User Interface
§ Plan/Set the Properties
§ Plan/Write the Code
§ Test and Debug

Ÿ Lists all files in the solution
Ÿ Displays the contents or a new project or open file
Ÿ The start up project is the project that runs when the program is
executed
It appears in bold in the SolutionExplorer
Ÿ The plus and minus images expand and collapse the tree
Can also double click on the file name to expand/collapse
Ÿ SolutionExplorer toolbar
The Refresh icon reloads files in the solution
The Display icon shows all files, even the hidden ones
