Question

I have a simple interface for caching stuff which goes like this

public interface ICacheService
{

        T Get<T>(string cacheId, Func<T> getItemCallback) where T : class;
}

and this works for simple callback functions but in my case I need to add something a bit more complex. I think it’s an anonymous type…

In the controller I am injecting a service that runs a query and this goes like this:

this.queryContainer.Get<ObjectQuery>().Execute(new ObjectParameters(id));

But of course this isn’t of type Func so if I try to use my caching service, the compiler complains.

What sort of interface do I need so that I can get my caching to work?
Ideally I want to do this:

this.cachingService.Get<ObjectResult>(id, this.queryContainer.Get<ObjectQuery>().Execute(new ObjectParameters(id)));

Is it even possible?

Any help is greatly appreciated!

Many thanks

You just need it expressed as a Func<T>?
Try this:

this.cachingService.Get<ObjectResult>(id, ()=> this.queryContainer.Get<ObjectQuery>().Execute(new ObjectParameters(id)));
