LINQ 101样品

从这里复制LINQ语句

string[] categories = new string[]{ 
    "Beverages", 
    "Condiments", 
    "Vegetables", 
    "Dairy Products", 
    "Seafood" };

List<Product> products = GetProductList();

var q =
    from c in categories
    join p in products on c equals p.Category
    select new { Category = c, p.ProductName };

foreach (var v in q)
{
    Console.WriteLine(v.ProductName + ": " + v.Category);
}
