I have an interface
with two implementations.
public interface ILogger
{
void Log(string message);
}
public class FileLogger : ILogger
{
public void Log(string message) {}
}
public class SQLiteLogger : ILogger
{
public void Log(string message) {}
}
I try using this code, but doesn't work.
ServiceContainer service = new ServiceContainer();
service.Register<ILogger, FileLogger>();
service.Register<ILogger, SQLiteLogger>();
LightInject
will omit the first registration and only register SQLiteLogger
.
So how to register same interface with multiple implementation in LightInject
?
This is called Named Services - which is quite standard across most IOC/DI containers that I've seen (see section on named services).
The documentation provides all the detail you need but here is a cut-and-paste from their website:
container.Register<IFoo, Foo>();
container.Register<IFoo, AnotherFoo>("AnotherFoo");
var instance = container.GetInstance<IFoo>("AnotherFoo");
Assert.IsInstanceOfType(instance, typeof(AnotherFoo));
