Generic Plugins

Hi i write a some plugins

it's look like that

public class Person
{
public string Name;
public string Surname;
}

public interface IWork
{
Type GetType {get;} 
}

public interface IWorker<T> : IWork
{
 T GetSingle();
 T[] GetMultiple();
 void DoWork(T object);
}

one plugin looks like that

public PersonPlugin : IWroker<Person>
{
//implementation of interface
//return typeof(Person);
}

And now question, how i can dynamic create a instance for example of IWork ? How cast as IWork if i have only Type, it's possible ?

i want to do (should be dynamic, for all instance of plugins)

IWork<T> iWorkInstalce = (IWork<T>)Activator.CreateInstance(typeof(PersonPlugin));

or

IWork iWorkInstalce = (IWork)Activator.CreateInstance(typeof(PersonPlugin)开发者_StackOverflow社区);
IWork<Person> personInstance = (CAST) typeof(IWork<>).MakeGenericType(iWorkInstance.Type);

You can't cast to IWorker<T> without specifying what T is. If you do that, your first example is valid:

IWorker<Person> iWorkInstalce = (IWorker<Person>)Activator.CreateInstance(typeof(PersonPlugin));

It is possible to use reflection on the PersonPlugin class to find it's implementation of IWorker<T>, and then discover what T is, but this is only any use as runtime, it won't help you at all in code.

If you know what you expect T to be, specify it explicitly. Otherwise, cast to the non-generic IWork instead and give it versions of your methods that return Object. If you don't know what T is at compile-time, having a generic IWorker<T> can't really help you here.

If your application needs to know what type your plugin works with at runtime, it can call the GetType property.
