假设有一个电子商务网站，需要按价格和销量对商品排序：

<syntaxhighlight lang="csharp">
using System;
using System.Linq;
using System.Collections.Generic;

class Product
{
    public string Name { get; set; }
    public decimal Price { get; set; }
    public int Sales { get; set; }
}

class Program
{
    static void Main()
    {
        List<Product> products = new List<Product>
        {
            new Product { Name = "Laptop", Price = 999.99m, Sales = 150 },
            new Product { Name = "Phone", Price = 699.99m, Sales = 300 },
            new Product { Name = "Tablet", Price = 499.99m, Sales = 200 }
        };

        // 按价格升序，销量降序排序
        var sortedProducts = products
            .OrderBy(p => p.Price)
            .ThenByDescending(p => p.Sales);

        Console.WriteLine("商品排序结果:");
        foreach (var product in sortedProducts)
            Console.WriteLine($"Name: {product.Name}, Price: {product.Price}, Sales: {product.Sales}");
    }
}
</syntaxhighlight>

'''输出:'''
<pre>
商品排序结果:
Name: Tablet, Price: 499.99, Sales: 200
Name: Phone, Price: 699.99, Sales: 300
Name: Laptop, Price: 999.99, Sales: 150
</pre>
