Enterprise-Grade Scraping for the .NET Ecosystem

What We Do With .NET / C# Web Scraping

• Strong typing with LINQ for elegant data transformation
• Async/await for non-blocking concurrent HTTP requests
• HtmlAgilityPack for robust HTML parsing with XPath
• AngleSharp for modern CSS selector-based extraction
• Azure Functions integration for serverless scraping
• Windows Service deployment for always-on monitoring

.NET / C# Web Scraping Tech Stack

using HtmlAgilityPack;
using System.Net.Http;

var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Add(
    "User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64)");

var html = await httpClient.GetStringAsync("https://example.com/products");

var doc = new HtmlDocument();
doc.LoadHtml(html);

var products = doc.DocumentNode
    .SelectNodes("//div[contains(@class,'product-card')]")
    ?.Select(node => new {
        Title = node.SelectSingleNode(".//h2")?.InnerText.Trim(),
        Price = node.SelectSingleNode(".//*[@class='price']")?.InnerText.Trim(),
    })
    .ToList();

foreach (var product in products ?? [])
    Console.WriteLine($"{product.Title}: {product.Price}");

* This is a simplified example. Production scrapers include error handling, proxies, and rate limiting.
