1.4 The Main Article
1.4.1 Introduction to C
C# (pronounced "C-sharp") is a modern, object-oriented programming language developed by Microsoft as part of its .NET initiative. It is designed for building a variety of applications that run on the .NET Framework, including web applications, desktop applications, and mobile applications. C# is known for its simplicity, versatility, and strong type safety, making it a popular choice among developers.
1.4.2 History of C
C# was created by Anders Hejlsberg and was first released in 2000 as part of the .NET Framework. Since then, it has undergone several revisions, with significant updates introduced in C# 2.0, 3.0, 4.0, and the latest versions, which include features like async/await, pattern matching, and records. The language has evolved to support modern programming paradigms and practices, making it suitable for a wide range of applications.
1.4.3 Key Features of C
1. Object-Oriented: C# supports the principles of object-oriented programming (OOP), including encapsulation, inheritance, and polymorphism. This allows developers to create modular and reusable code.
2. Type Safety: C# is a statically typed language, meaning that type checking is done at compile time. This helps catch errors early in the development process.
3. Rich Library Support: The .NET Framework provides a vast library of pre-built classes and functions, enabling developers to perform common tasks without having to write code from scratch.
4. Cross-Platform Development: With the introduction of .NET Core and now .NET 5 and later, C# can be used to develop applications that run on multiple platforms, including Windows, macOS, and Linux.
5. Asynchronous Programming: C# supports asynchronous programming through the async and await keywords, allowing developers to write non-blocking code that improves application responsiveness.
1.4.4 C# Syntax Basics
1.4.4.1 Variables and Data Types
In C#, variables are used to store data, and each variable must have a specific data type. Common data types include:
- int
: Represents integer values.
- double
: Represents floating-point numbers.
- char
: Represents a single character.
- string
: Represents a sequence of characters.
- bool
: Represents a boolean value (true or false).
Example:
```csharp
int age = 30;
double height = 5.9;
char initial = 'A';
string name = "John Doe";
bool isEmployed = true;
```
1.4.4.2 Control Structures
Control structures allow developers to dictate the flow of execution in a program. Common control structures include:
- If Statements: Used for conditional execution.
- Switch Statements: Used for multi-way branching.
- Loops: Such as for
, while
, and foreach
, used for repeated execution.
Example:
```csharp
if (age > 18)
{
Console.WriteLine("Adult");
}
else
{
Console.WriteLine("Minor");
}
```
1.4.4.3 Functions
Functions (or methods) are blocks of code that perform a specific task. They can take parameters and return values.
Example:
```csharp
public int Add(int a, int b)
{
return a + b;
}
```
1.4.5 Object-Oriented Programming in C
C# is fundamentally an object-oriented language, which means it allows developers to create classes and objects.
1.4.5.1 Classes and Objects
A class is a blueprint for creating objects. An object is an instance of a class.
Example:
```csharp
public class Car
{
public string Make { get; set; }
public string Model { get; set; }
public void Drive()
{
Console.WriteLine("Driving the car");
}
}
Car myCar = new Car();
myCar.Make = "Toyota";
myCar.Model = "Corolla";
myCar.Drive();
```
1.4.5.2 Inheritance
Inheritance allows a class to inherit properties and methods from another class. This promotes code reuse.
Example:
```csharp
public class Vehicle
{
public void Start()
{
Console.WriteLine("Vehicle started");
}
}
public class Motorcycle : Vehicle
{
public void Rev()
{
Console.WriteLine("Revving the motorcycle");
}
}
Motorcycle myBike = new Motorcycle();
myBike.Start();
myBike.Rev();
```
1.4.5.3 Polymorphism
Polymorphism allows methods to do different things based on the object that it is acting upon. This can be achieved through method overriding and interfaces.
Example:
```csharp
public class Animal
{
public virtual void Speak()
{
Console.WriteLine("Animal speaks");
}
}
public class Dog : Animal
{
public override void Speak()
{
Console.WriteLine("Bark");
}
}
Animal myDog = new Dog();
myDog.Speak(); // Outputs: Bark
```
1.4.6 Advanced C# Concepts
1.4.6.1 Delegates
Delegates are type-safe function pointers that allow methods to be passed as parameters.
Example:
```csharp
public delegate void Notify(string message);
public class Process
{
public event Notify ProcessCompleted;
public void StartProcess()
{
// Process logic here
ProcessCompleted?.Invoke("Process completed successfully");
}
}
```
1.4.6.2 Events
Events are a way for a class to provide notifications to clients when something of interest occurs.
Example:
```csharp
public class Publisher
{
public event EventHandler Notify;
public void RaiseEvent()
{
Notify?.Invoke(this, EventArgs.Empty);
}
}
```
1.4.6.3 LINQ (Language Integrated Query)
LINQ is a powerful feature in C# that allows querying of collections in a concise and readable manner.
Example:
```csharp
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
var evenNumbers = from n in numbers where n % 2 == 0 select n;
```
1.4.6.4 Asynchronous Programming
Asynchronous programming is essential for building responsive applications. The async
and await
keywords simplify the process of writing asynchronous code.
Example:
```csharp
public async Task<string> GetDataAsync()
{
await Task.Delay(1000); // Simulate a delay
return "Data retrieved";
}
```
1.4.7 Error Handling in C
Error handling is crucial for building robust applications. C# provides a structured way to handle exceptions using try-catch blocks.
Example:
```csharp
try
{
int result = 10 / 0; // This will throw an exception
}
catch (DivideByZeroException ex)
{
Console.WriteLine("Cannot divide by zero: " + ex.Message);
}
```

public class CalculatorTests
{
[TestMethod]
public void TestAdd()
{
Calculator calc = new Calculator();
Assert.AreEqual(5, calc.Add(2, 3));
}
}
```
