Unit title: Planning and Programming using Visual C#.Net
Year 2013
Version 3
Introduction
This unit plan is designed for a Year 11 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).

Curriculum Level 6
Students can:
Students can:
o
specify variables and their data types
o
independently construct a flexible and robust plan
o
specify a procedural structure that combines well-chosen actions,

Thinking skills – actively seek, use and create

Using language, symbols and text – representing and

Managing self – setting goals, manage projects,
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
conditions and control structures that constitutes a well-structured
logical solution to the task
o
knowledge
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
specify a comprehensive set of test cases with expected, boundary
and invalid input for testing the program.
o
independently implement a plan for a basic program in a suitable
programming language that uses a procedural structure with wellchosen actions, conditions and control structures that ensures the
program is flexible and robust
o
set out a program's code concisely, and document the program
with variable names and succinct comments that accurately explain
and justify code function and behaviour
o
comprehensively test and debug the program in an organised time
effective way to ensure that it works on expected, boundary and
invalid inputs
o

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
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.
String Manipulation
Do sections 1, 8, 9
Events
Do sections 1 - 5

Graphics in C#
use resource How to create graphics for drawing.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
First on a simple problem. (Use resource …Level 1_Catch the Alien.docx)
Then on a Dodge type game. (use resource … Level 1_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.
