Unit title: Planning and Programming using Visual C#.Net
Year 2013
Version 3
Introduction
This unit plan is designed for a Year 12 class, and aims to cover efficiently planning and constructing a basic computer program
for a specified task. The software used is Visual C#.Net (2010 Express version freely available from Microsoft).

Technological Context Knowledge and Skills – Objectives
o
o
Demonstrate ability to design the structure of an advanced
software program
Demonstrate ability to construct an advanced software program
Curriculum Level 7
Students can:
Students can:
o
specify well-chosen scopes for variables, their scopes and data types.
o
specify an indexed data structure.
o
specify a modular structure for the program with well-chosen
parameters, including details of the procedural structures of the
modules, that constitute a well-structured logical decomposition of the
task.
o
specify a comprehensive set of expected, boundary and exceptional
input cases for testing the program.
o
specify variables, constants, and derived values effectively so as to
maximise the flexibility and robustness of an independently constructed
plan.
o
independently implement a plan for an advanced program in a suitable
programming language (preferably a text- based programming
language).
o
construct an advanced program where the modules (including their
procedural structures) constitute a well-structured logical decomposition
of the task.
o
use variables, constants, and derived values effectively so as to increase
the flexibility and robustness of the program.
o
set out the program code clearly and concisely and document the
program with comments that explain and justify decisions.
o
comprehensively test and debug the program in an organised and time
effective way to ensure the program is correct on expected, boundary
Key Competencies

Thinking skills – actively seek, use and create

Using language, symbols and text – representing and

Managing self – setting goals, manage projects,
knowledge
communicating information and ideas using a high
level language (e.g. Visual CSharp.Net)
working independently

Relating to others – students interact with others in

Participating and contributing – students participate
the classroom (teacher and students) making
informed decisions using feedback from teacher
and/or peers
fully in each lesson, sharing knowledge and creating
learning opportunities for others
and invalid inputs.

Introduction to C# programming
Console application
Saving work
Program Class
main Method
Using the intellisense menu
running programs (debugging)
using toolbox to add controls to a form
properties
code
messageboxes
http://www.homeandlearn.co.uk/
Visual C#.Net programming
C#.Net Getting Started
Start with demonstrating console application (Don’t do the cmd
line section as our students are locked out of this)
Students save work to My Documents\Visual Studio 2010\Projects and
back this up to their Home drive later.
First line of code
How to Run a C# program
First C# windows form
Adding controls to a form
properties of a control
adding code to a button
C# message boxes
More about C# message boxes
Variables
strings, concatenation; comments; numbers variables:
integer, Float and Double; addition, subtraction,
operators, getting numbers from text boxes.
Students work through: C#.Net variables section
Conditional Logic
if; if .. else; else ..if; switch, conditional operators
Students work through: C#.Net variables section
Loops
for, list boxes, Do loops,
C# loops
from string variables to 18 the equals button
This section includes developing a simple calculator)
Do Exercises A, B C and the other non lettered exercises
Exercise D, E, F
Exercise G, H
Add Menus
Using menus
C# add Menus to your forms
do 1. Add Menus …
3. menu shortcuts
debugging
Design-time errors, Run-Time errors, Logical errors,
breakpoints, the locals window
C# Debugging
Design-time errors, Run-Time errors, Logical errors,
breakpoints, the locals window
Exercise I
C# Methods
C# Methods
understanding methods, passing values, returning values.

C# Arrays
Arrays
Understanding arrays. Plus resource: Arrays in CSharp (looks at the
random class as well)
String Manipulation
Do sections 1, 8, 9
Events
Do sections 1 - 5
Classes and objects
(students get general idea from website. Then reinforce the
concepts of OOP with the resource, in particular
encapsulation)
Graphics in C#
Do up to 7. Class Constructors
Validating input from users
use resource … 201_COS_Some input validation techniques.docx
Designing a Visual C#.Net program (or any program)
The steps we will look at are:
1. Investigate and understand the problem
2. Plan/Design the algorithm (we will use
pseudocode)
3. Implement the solution.
4. Debugging and testing the solution.
Demonstrate the steps
Then
use resource Object Oriented Programming.docx
use resource How to create graphics for drawing.docx
First on a simple problem. (Use resource Level2_Catch the Alien.docx)
Then on a Dodge type game. (use resource … Level Two_CSharp
Dodge.docx)
This is the Programming Process. It is iterative, we keep
coming back to the steps. It could be 3 and 4 repeated or
we might need to revise our plan then implement and test
again.
