CLR
Robust and secure environment for your managed

code

Foundation of common functionality
Extensible
Development frameworks
WPF
Windows store
ASP.NET
WCF

Слайд 5

Key Features of Visual Studio 2012
Intuitive IDE
Rapid application development
Server and data

access
IIS Express
Debugging features
Error handling
Help and documentation

Слайд 7

Creating a .NET Framework Application
In Visual Studio, on the File menu,

point to New, and then click Project.
In the New Project dialog box, choose a template, location, name, and then click OK.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args) { }
}
}

Слайд 8

Overview of XAML
XML-based language for declaring UIs
Uses elements to define controls
Uses

attributes to define properties of controls

Слайд 9

Lesson 2: Data Types, Operators, and Expressions
What are Data Types? Expressions and

Operators in Visual C# Declaring and Assigning Variables Accessing Type Members Casting Between Data Types Manipulating Strings

Слайд 10

What are Data Types?
int – whole numbers
long – whole numbers (bigger

range)
float – floating-point numbers
double - double precision
decimal - monetary values
char - single character
bool - Boolean
DateTime - moments in time
string - sequence of characters

Слайд 11

Expressions and Operators in Visual C#
Example expressions:
+ operator
/ operator
+ and –

operators
+ operator (string concatenation)

a + 1

5 / 2

a + b - 2

"ApplicationName: " + appName.ToString()

Слайд 12

Declaring and Assigning Variables
Declaring variables:
Assigning variables:
Implicitly typed variables:
Instantiating object variables by

using the new operator

int price;
// OR
int price, tax;

price = 10;
// OR
int price = 10;

var price = 20;

ServiceConfiguration config = new ServiceConfiguration();

Слайд 13

Accessing Type Members
Invoke instance members
Example:
var config = new ServiceConfiguration();
// Invoke the

LoadConfiguration method.
config.LoadConfiguration();
// Get the value from the ApplicationName property.
var applicationName = config.ApplicationName;
// Set the .DatabaseServerName property.
config.DatabaseServerName = "78.45.81.23";
// Invoke the SaveConfiguration method.
config.SaveConfiguration();

Слайд 14

Casting Between Data Types
Implicit conversion:
Explicit conversion:
System.Convert conversion:
int a = 4;
long b

= 5;
b = a;

int a = (int) b;

string possibleInt = "1234";
int count = Convert.ToInt32(possibleInt);

Слайд 15

Manipulating Strings
Concatenating strings
Validating strings
StringBuilder address = new StringBuilder();
address.Append("23");
address.Append(", Main Street");
address.Append(", Buffalo");
string

concatenatedAddress = address.ToString();

var textToTest = "hell0 w0rld";
var regularExpression = "\\d";
var result = Regex.IsMatch(textToTest, regularExpression, RegexOptions.None);
if (result)
{
// Text matched expression.
}

Слайд 16

Lesson 3: Visual C# Programming Language Constructs
Implementing Conditional Logic Implementing Iteration Logic Creating

and Using Arrays Referencing Namespaces Using Breakpoints in Visual Studio 2012 Demonstration: Developing the Class Enrollment Application Lab

Слайд 17

Implementing Conditional Logic
if statements
select statements
if (response == "connection_failed") {. . .}
else

if (response == "connection_error") {. . .}
else { }

switch (response)
{
case "connection_failed":
. . .
break;
case "connection_success":
. . .
break;
default:
. . .
break;
}

Слайд 18

Implementing Iteration Logic
for loop
foreach loop
while loop
do loop
for (int i = 0

; i < 10; i++) { ... }

string[] names = new string[10];
foreach (string name in names) { ... }

bool dataToEnter = CheckIfUserWantsToEnterData();
while (dataToEnter)
{
...
dataToEnter = CheckIfUserHasMoreData();
}

do
{
...
moreDataToEnter = CheckIfUserHasMoreData();
} while (moreDataToEnter);

Слайд 19

Creating and Using Arrays
C# supports:
Single-dimensional arrays
Multidimensional arrays
Jagged arrays
Creating an array
Accessing data

in an array:
By index
In a loop

int[] arrayName = new int[10];

int result = arrayName[2];

for (int i = 0; i < arrayName.Length; i++)
{
int result = arrayName[i];
}

Слайд 20

Referencing Namespaces
Use namespaces to organize classes into a logically related hierarchy
.NET

Class Library includes:
System.Windows
System.Data
System.Web
Define your own namespaces:
Use namespaces:
Add reference to containing library
Add using directive to code file

namespace FourthCoffee.Console
{
class Program {. . .}

Слайд 21

Using Breakpoints in Visual Studio 2012
Breakpoints enable you to view and

modify the contents of variables:
Immediate Window
Autos, Locals, and Watch panes
Debug menu and toolbar functions enable you to:
Start and stop debugging
Enter break mode
Restart the application
Step through code

Lab Scenario
You are a Visual C# developer working for a software

development company that is writing applications for The School of Fine Arts, an elementary school for gifted children.
The school administrators require an application that they can use to enroll students in a class. The application must enable an administrator to add and remove students from classes, as well as to update the details of students.
You have been asked to write the code that implements the business logic for the application.
During the labs for the first two modules in this course, you will write code for this class enrollment application.
When The School of Fine Arts ask you to extend the application functionality, you realize that you will need to test proof of concept and obtain client feedback before writing the final application, so in the lab for Module 3, you will begin developing a prototype application and continue with this until then end of Module 8.
In the lab for Module 9, after gaining signoff for the final application, you will develop the user interface for the production version of the application, which you will work on for the remainder of the course.
