A Simple Class Example

This example demonstrates creating a class and using its properties:

public class Person {     public string Name { get; set; }     public int Age { get; set; }      public void Introduce()     {         Console.WriteLine($"Hello, my name is {Name} and I am {Age} years old.");     } }  // Usage Person person = new Person(); person.Name = "Alice"; person.Age = 30; person.Introduce();

LINQ Query Example

LINQ (Language Integrated Query) provides a powerful way to query data from various sources:

using System.Linq;  int[] numbers = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };  var evenNumbers = numbers.Where(n => n % 2 == 0);  foreach (var number in evenNumbers) {     Console.WriteLine(number); }

Asynchronous Programming

Here's an example of asynchronous programming using `async` and `await`:

using System.Threading.Tasks;  public async Task<string> DownloadDataAsync(string url) {     using (HttpClient client = new HttpClient())     {         HttpResponseMessage response = await client.GetAsync(url);         response.EnsureSuccessStatusCode();         return await response.Content.ReadAsStringAsync();     } }  // Usage string data = await DownloadDataAsync("https://example.com/data"); Console.WriteLine(data);

Alternatives to C#: Weighing Your Options 🤔

While C# is a versatile language, it's important to consider alternatives that might be better suited for specific projects:

Java

Java is a mature and widely used language with a large ecosystem and strong cross-platform support. It's a good alternative to C# for building enterprise-level applications and Android mobile apps.

HTML Structure

<div id="code-editor">     <textarea id="csharp-code"> using System;  public class Program {     public static void Main(string[] args)     {         Console.WriteLine("Hello, Interactive World!");     } }     </textarea>     <button onclick="executeCSharpCode()">Run Code</button>     <div id="output"></div> </div>

JavaScript Function to Execute C# Code

function executeCSharpCode() {     var code = document.getElementById('csharp-code').value;     // Simulate execution by sending code to a server and displaying the result     // In a real scenario, you'd send an AJAX request to a server that compiles and runs the C# code     var outputDiv = document.getElementById('output');     outputDiv.innerHTML = 'Executing code...\n';     // Mock output (replace with actual server response)     setTimeout(function() {         outputDiv.innerHTML += 'Hello, Interactive World!\n';     }, 1000); }

Explanation

• HTML Structure:
• A textarea where users can input C# code.
• A button to trigger the code execution.
• A div to display the output.
• JavaScript Function:
• The executeCSharpCode() function retrieves the C# code from the textarea.
• It simulates code execution by updating the output div.
• In a real-world scenario, you would send an AJAX request to a server that compiles and runs the C# code, then returns the output to be displayed.
