我有一个来自数据库的产品列表，格式与以下代码生成的格式相同：

 public class Product
 { 
    int Id { get; set; }
    string Name { get; set; }
    string Color { get; set; }
    string Size { get; set; }
    string Pattern { get; set; }
    string Material { get; set; }
    string Weight { get; set; }
    string Resolution { get; set; }
    float Price { get; set; }
 }


List<Product> products = new List<Product>();

products.Add(new Product(1,"blouse","red","S","stripes","cotton",null,10));
products.Add(new Product(2,"dots",11));
products.Add(new Product(3,"M",10));
products.Add(new Product(4,11));
products.Add(new Product(5,"green",15));
products.Add(new Product(6,16));
products.Add(new Product(7,15));
products.Add(new Product(8,16));

在数据库表中，我存储了各种产品，但是需要一种方法，该方法可以根据某些参数动态地对产品列表进行分组。 例如，函数

Object productGroup = GroupProductsByParameters("Color","Size","Pattern");

应返回结构为：

{
  "Name": "blouse","Variations": [{
      "Id": "1","Color": "red","Size": "S","Pattern": "stripes","Price": "10"
    },{
      "Id": "2","Pattern": "dots","Price": "11"
    },.
    .
    .
    ],"Material": "cotton","Weight": "","Resolution": ""
}

请注意，我不一定需要将分组参数作为字符串传递给函数，根据我在产品列表中拥有的产品类型，它们很可能来自数据库。 （电视将按重量和分辨率分组）
