LinqToLcbo is a custom LINQ Provider that allows querying the LCBO for products, stores, and inventories. Internally, queries translate into Web service calls sent to the LCBO API. For detailed API information please see the [LCBO API Documentation] (http://http://lcboapi.com/docs/about).
var lcbo = new LcboDataSource();
var products = lcbo product in data.Products
where product.SearchQuery == "heineken" && !product.IsDiscontinued
orderby product.Price
select product;
//Alternatively using lambda expressions
var products = lcbo.Products
.Where(o => !o.IsDiscontinued && o.SearchQuery == "heineken")
.OrderBy(o=>o.Price);
foreach (Product p in products)
Console.WriteLine(p.Name); var lcbo = new LcboDataSource();
var stores = (from s in lcbo.Stores
where s.Geolocation == "Spadina"
orderby s.Distance
select s).ToList();
var products = from p in stores[0].Products
where p.SearchQuery == "heineken"
select p;
//Alternatively using lambda expressions
var stores = lcbo.Stores.Where(o => o.Geolocation == "Spadina").OrderBy(o => o.Distance).ToList();
var products = stores[0].Products.Where(o => o.SearchQuery == "heineken");
foreach (Product p in products)
Console.WriteLine(p.Name); var lcbo = new LcboDataSource();
Inventory inventoryAtKing = (from i in lcbo.Inventories
where i.ProductId == 18 && i.StoreId == 511
select i).Single();
//Alternatively using lambda expressions
Inventory inventoryAtKing = lcbo.Inventories.Single(o => o.StoreId == 511 && o.ProductId == 18);
Console.WriteLine(inventoryAtKing.Quantity);This project is an exercise in demonstrating the flexibility of LINQ. Since LINQ works as a language pattern (like foreach), implementing IQueryable is not necessary. Instead, this project only implements a subset of the Standard Query Operators to provide a rich compiler enforced query syntax.
