Initialization of objects in the background

I need to initialize few objects, it can take a while so I want to do it in some background thread. I also want to display progressBar showing what is the progress of initialization.

What is the 开发者_运维知识库most elegant way to do it?

I was thinking about an interface:

interface ILoadable
{
    int Progress { get; }
    event EventHandler Loaded;
}

Why not just use a BackgroundWorker directly? It provides events for DoWork, ProgressChanged, and RunWorkerCompleted.

The advantage of this (or a thin wrapper over this) is that you automatically get the threading handled for you, properly, and it's very well tested.

If you want to make a wrapper around this, I'd actually recommend making yourself an abstract class that encapsulates the BackgroundWorker, and lets you provide Action delegates for the run operation.
