Question

I have a windows application (C# , .Net 4.0). This windows application is plugin based. I would like to pass an object from the main application to a plugin.

Somebody care to show me an example please? .

Answer 1

funny you should ask this, i’m working on something like this right now.

In the Interface that you are defining for the Plugins, provide a method/property that is the Interface from your application that the plugin can use.

Then inside your application implement that interface.

Now on your plugin call your Method passing in that Class that.

Now inside the plugin it will be able to utilise the methods and properties you have designed in the interface.

interface IPlugin
{
    void CanBeCalledByTheApplication(IAppObject main);
}


interface IAppObject
{
    void Alert(string msg);
}

Now in your implementation of the plugin you can just go

 main.Alert("this is my message");

And in your application you’d go

(IPlugin)myPlugin.CanBeCalledByTheApplication(someObject);

This is obviously not a complete example, but you should be able to get the idea.
