FileContext is a data access layer (DAL) Framework for Rapid Data Driven Application Development (RDDAD).
###benefits
- you don't need a database
- rapid data-modelling, -modification
- share your informations with version-control
- quick synchronisation between environments (test -> dev)
- all serializable .NET types are allowed (DateTime.Min, TimeSpan > 24h,...)
- all linq queries with extension-methods as FilterExpression are allowed
- rapid migration to Entity-Framework 6.*
- Generic repository pattern included
- Unit of work pattern included
- Threadsafe for prototyping
- Different store strategies (Xml,Json,InMemory,MongoDb,Cache)
- Caching as store wrapper
- Support transactions
- Support disconnected entities
hint: don't use for production.
###nuget
###Todo: in two steps to FileContext modify EntityFramework DbContext to FileContext
- Replace DbContext to FileContext
- Replace DbSet to FileSet
###Example Code:
var unit = new UnitOfWork(new Context()); //new Context(new InMemoryStoreStrategy())
//INSERT
Console.WriteLine("INSERT PAUL");
unit.UserRepository.Insert(new User() { UserName="pmizel",
FirstName="Paul",
LastName="Mizel",
Birthday=new DateTime(1980,4,1)});
Console.WriteLine("INSERT FABIAN");
unit.UserRepository.Insert(new User() { UserName = "fraetz",
FirstName = "Fabian",
LastName = "Raetz",
Birthday = new DateTime(1989, 4, 1)});
unit.Save();
Console.WriteLine("GET ALL");
var users=unit.UserRepository.Get(); //GET ALL
foreach (var user in users)
{
Console.WriteLine("{0} {1} ({2})", user.FirstName, user.LastName, user.UserName);
}
Console.WriteLine("GET Youngest");
var youngest = unit.UserRepository.Get(orderBy: o => o.OrderByDescending(i => i.Birthday)).First();
Console.WriteLine("{0} {1} ({2}) - {3:dd.MM.yyyy}", youngest.FirstName,
youngest.LastName,
youngest.UserName,
youngest.Birthday);
Console.WriteLine("GET PAULs");
users = unit.UserRepository.Get(f=>f.FirstName=="Paul"); //GET ALL
foreach (var user in users)
{
Console.WriteLine("{0} {1} ({2})", user.FirstName, user.LastName, user.UserName);
}
Console.WriteLine("UPDATE PAULs to PABLOs");
foreach (var user in users)
{
user.FirstName = "Pablo";
unit.UserRepository.Update(user);
}
unit.Save();
Console.WriteLine("GET ALL");
users = unit.UserRepository.Get(); //GET ALL
foreach (var user in users)
{
Console.WriteLine("{0} {1} ({2})", user.FirstName, user.LastName, user.UserName);
}
//DELETE ALL
Console.WriteLine("DELETE ALL");
unit.UserRepository.Delete(unit.UserRepository.Get());
users = unit.UserRepository.Get();
foreach (var user in users)
{
Console.WriteLine("{0} {1} ({2})", user.FirstName, user.LastName, user.UserName);
}
unit.Save();###Output:
INSERT PAUL
INSERT FABIAN
GET ALL
Paul Mizel (pmizel)
Fabian Raetz (fraetz)
GET Youngest
Fabian Raetz (fraetz) - 01.04.1989
GET PAULs
Paul Mizel (pmizel)
UPDATE PAULs to PABLOs
GET ALL
Fabian Raetz (fraetz)
Pablo Mizel (pmizel)
DELETE ALL###Example Context:
//public class ContentItemContext : DbContext
public class ContentItemContext : FileContext
{
public ContentItemContext()
: base("name=ContentItemContext")
{
}
public FileSet<ContentItem> ContentItems { get; set; }
//public DbSet<ContentItem> ContentItems { get; set; }
}###StoreStrategy
//public class ContentItemContext : DbContext
public class ContentItemContext : FileContext
{
public ContentItemContext()
: base(new JsonStoreStrategy())
// or DefaultStoreStrategy() => XmlStoreStrategy()
// or InMemoryStoreStrategy()
{
}
public FileSet<ContentItem> ContentItems { get; set; }
//public DbSet<ContentItem> ContentItems { get; set; }
}for UnitTests/IntegrationsTests use InMemoryStoreStrategy instance.
