CPSC Tutorial 4 Visual Studio and C#

Transcription

1 CPSC Tutorial 4 Visual Studio and C# (based on previous tutorials by Alice Thudt, Fateme Rajabiyazdi, David Ledo, Brennan Jones, and Sowmya Somanath)

2 Today Intro to Assignment 2 Visual Studio Intro to C#

3 1. Assignment 2 Details

4 Assignment 2 Continuation of the interface your team started designing (ideally). Two more design evolutions: 1. Horizontal medium-fidelity prototype (20%) 2. Moderately robust system that implements vertical functionality (80%) Prototype using C# Perform a heuristic evaluation

5 Horizontal Prototype Deadline: Mar. 7-9 in class: 1. Write-up including redesign rational (i.e., changes from the first prototype), screen snapshots, and a grading sheet (from assignment handout) 2. Horizontal prototype presentation freeze Submission either: to me (kta@ucalgary.ca) Submit on a USB along with your write-up

6 Horizontal Prototype Presentations Tuesday Mar 7 in tutorial (T01) Thursday Mar 9 in tutorial (T02)

7 Main Project Deadlines Friday Apr. 7 in class: 1. Complete portfolio (Assignment 1 + new stuff) 2. Redesign rational 3. Implementation freeze no more changing code after this point 4. Latest screen snapshots 5. Heuristic evaluation of final system 6. Final discussion 7. USB/DVD: All source code (project) Required data files README file

8 Final Project Demonstrations April 10-14: Demos will be STRICTLY run from the submitted USB/DVD media ALL team members must participate

9 What should we do now?

10 Horizontal Prototype Write-up: Two-page redesign rational (main reasons for change) Screen snapshots of your screens (but not counted towards the two-page count)

11 Horizontal Prototype Presentation slide deck + writeup: MUST be submitted on Monday Mar 6 in lecture (with your write-up) Present screen snapshots of your medium-fi prototype

12 Main Project Redesign your interface (again): Evaluate your interface using any of the following: Heuristic evaluation Walkthrough Or others you learnt in class Implement a substantial part of the vertical functionality (screens, error messages, input handling, etc) Anything that you think is interesting should be functional and demo-able

13 Main Project Heuristic Evaluation: Evaluate your FINAL interface using the heuristic evaluation method This is a second evaluation

14 Main Project Electronic submission (USB/DVD): All source code and data files for the final version of your working project README file your names, instructions on how to use the system, what cases/functions were implemented, what kind of data needs to be input, etc. Test your code on the lab machine before you submit

15 Main Project Final demonstration: You will demo to me and Ehud (a timetable will be posted by me) Test your demo on the lab computer and using the projector before the final demo

16 Timeline Date Deliverable (refer to assignment 2 specifications) March 6th In Lecture Horizontal Prototype Redesign writeup Horizontal Prototype Presentations freeze March 7-9 In Tutorial Horizontal Prototype presentations in tutorial (20% of mark) Bring your grading sheets! April 7 In Lecture Final Project submission (portfolio, implementation freeze, evaluation, screenshots, etc) April Finals Project Demonstrations

21 2. Visual Studio Using Visual Studio

22 Visual Studio Visual Studio 2015 Professional is installed on the lab machines You may download Visual Studio 2015 onto your machine for free here Select Visual Studio Community 2015 It is a big download (> 5GB)

23 Optional: Version Control BitBucket (git/mercurial): Free private repositories for up to 5 collaborators Optional, it might help you collaborate Github (git): Popular, but private repos are paid Desktop app: Guide to Git:

24 Optional: SVN Accounts For those who want an SVN account, go to the CPSC help desk and ask for one OR CPSC Help Desk: Request for an SVN account Include members IT account usernames or all usernames you wish to have access to it State it is for your CPSC 481 group project

25 Optional: SVN Accounts We won t go over this in tutorial, but here are some resources that can help you: AnkhSVN: php/visualstudio/subversion VisualSVN: TortoiseSVN: Guide to Git:

41 3. Intro to C# Basics

42 C# C# compared to Java Naming conventions Namespace Classes Properties and Fields Methods Create a more complex console application

43 Naming Conventions Every language has its own naming conventions E.g., Java uses camelcasing, while C# uses camelcasing for variables and PascalCasing for methods int myinteger; public void ReturnResults(){ }

44 Naming Conventions A lot of people like to call instance variables (or fields) starting with an underscore: int _instancevar; Interfaces always start with an I (e.g. ICloneable)

45 Comments // This is a single-line comment /* This is a multi-line comment */ /// This is how you describe methods /** (This is how you describe methods in Java) */

46 Access Modifiers public accessible anywhere private only accessible within the class or struct protected only accessible within the same hierarchy internal only accessible by the same assembly

47 Access Modifiers A property is a member that provides a flexible mechanism to read, write, or compute the value of a private field Also called accessor methods Properties are public methods Properties enable a class to expose a public way of getting and setting values, while hiding implementation or verification code

48 Properties A get property accessor is used to return the property value A set accessor is used to assign a new value The value keyword is used to define the value being assigned by the set accessor Properties that do not implement a set accessor are read only

49 Properties class TimePeriod { private double seconds; public double Hours { get { return seconds / 3600; } set { seconds = value * 3600; } } }

50 Using Properties class Program { static void Main() { TimePeriod t = new TimePeriod(); // Assigning the Hours property calls the 'set' accessor t.hours = 24; // Evaluating the Hours property calls the 'get' accessor System.Console.WriteLine("Time in hours: " + t.hours); } }

51 Foreach Loop using System.Collections; ArrayList list = new ArrayList(); list.add(1); list.add(2); foreach (int i in list) { int j = i; }

52 Foreach Loop If you use generic containers (e.g., ArrayList), casting is implicit Unlike Java where you have to explicitly cast

53 Inheritance public class ChildClass : InterfaceName public class ChildClass : ParentClass public class ChildClass : ParentClass, IInterface1, IInterface2

54 Inheritance Base class Max 1 inheritance Interfaces One or more interfaces

55 Other Differences If a class, property, or field does not have an access modifier, it is private by default So every time you create a class, add the word public at the beginning Console applications have the console close at the very end of the program

56 Other Differences In C# Strings can be primitives Booleans are denoted bool Java s ArrayList<type> is List<type> in C# Java s list.length is list.count in C#
