Simple example using Redis Lists
　　Below is a simple example to give you a flavour of how easy it is to use some of Redis's advanced data structures - in this case Redis Lists: Full source code of this example is viewable online

using (var redisClient = new RedisClient())
{
//Create a 'strongly-typed' API that makes all Redis Value operations to apply against Shippers
IRedisTypedClient redis = redisClient.GetTypedClient();
//Redis lists implement IList while Redis sets implement ICollection
var currentShippers = redis.Lists["urn:shippers:current"];
var prospectiveShippers = redis.Lists["urn:shippers:prospective"];
currentShippers.Add(
new Shipper {
Id = redis.GetNextSequence(),
CompanyName = "Trains R Us",
DateCreated = DateTime.UtcNow,
ShipperType = ShipperType.Trains,
UniqueRef = Guid.NewGuid()
});
currentShippers.Add(
new Shipper {
Id = redis.GetNextSequence(),
CompanyName = "Planes R Us",
DateCreated = DateTime.UtcNow,
ShipperType = ShipperType.Planes,
UniqueRef = Guid.NewGuid()
});
var lameShipper = new Shipper {
Id = redis.GetNextSequence(),
CompanyName = "We do everything!",
DateCreated = DateTime.UtcNow,
ShipperType = ShipperType.All,
UniqueRef = Guid.NewGuid()
};
currentShippers.Add(lameShipper);
Dump("ADDED 3 SHIPPERS:", currentShippers);
currentShippers.Remove(lameShipper);
Dump("REMOVED 1:", currentShippers);
prospectiveShippers.Add(
new Shipper {
Id = redis.GetNextSequence(),
CompanyName = "Trucks R Us",
DateCreated = DateTime.UtcNow,
ShipperType = ShipperType.Automobiles,
UniqueRef = Guid.NewGuid()
});
Dump("ADDED A PROSPECTIVE SHIPPER:", prospectiveShippers);
redis.PopAndPushBetweenLists(prospectiveShippers, currentShippers);
Dump("CURRENT SHIPPERS AFTER POP n' PUSH:", currentShippers);
Dump("PROSPECTIVE SHIPPERS AFTER POP n' PUSH:", prospectiveShippers);
var poppedShipper = redis.PopFromList(currentShippers);
Dump("POPPED a SHIPPER:", poppedShipper);
Dump("CURRENT SHIPPERS AFTER POP:", currentShippers);
//reset sequence and delete all lists
redis.SetSequence(0);
redis.Remove(currentShippers, prospectiveShippers);
Dump("DELETING CURRENT AND PROSPECTIVE SHIPPERS:", currentShippers);
}

Speed
　　One of the best things about Redis is the speed - it is quick.
　　This example below stores and gets the entire Northwind database (3202 records) in less 1.2 secs - we've never had it so quick!
　　(Running inside a VS.NET/R# unit test on a 3 year old iMac)

using (var client = new RedisClient())
{
var before = DateTime.Now;
client.StoreAll(NorthwindData.Categories);
client.StoreAll(NorthwindData.Customers);
client.StoreAll(NorthwindData.Employees);
client.StoreAll(NorthwindData.Shippers);
client.StoreAll(NorthwindData.Orders);
client.StoreAll(NorthwindData.Products);
client.StoreAll(NorthwindData.OrderDetails);
client.StoreAll(NorthwindData.CustomerCustomerDemos);
client.StoreAll(NorthwindData.Regions);
client.StoreAll(NorthwindData.Territories);
client.StoreAll(NorthwindData.EmployeeTerritories);
Console.WriteLine("Took {0}ms to store the entire Northwind database ({1} records)",
(DateTime.Now - before).TotalMilliseconds, totalRecords);

before = DateTime.Now;
var categories = client.GetAll();
var customers = client.GetAll();
var employees = client.GetAll();
var shippers = client.GetAll();
var orders = client.GetAll();
var products = client.GetAll();
var orderDetails = client.GetAll();
var customerCustomerDemos = client.GetAll();
var regions = client.GetAll();
var territories = client.GetAll();
var employeeTerritories = client.GetAll();
Console.WriteLine("Took {0}ms to get the entire Northwind database ({1} records)",
(DateTime.Now - before).TotalMilliseconds, totalRecords);
}
/*
