Call controller action from non controller class

Question

Is there a way to invoke a controller action from a regular C# class, that is not a controller?

All I found so far uses redirectToAction, but this is controller exclusive.

Answer 1

A controller is a class like any other, which means you can do this:

var homeController = new HomeController();

(assuming you have your project references setup, I'm not including namespaces in my example, as I don't know what yours are)

Thus you can then execute the methods of that controller via the homeController variable. But, as has been pointed out in the comments, this is not a good design at all. I would strongly recommend you don't do this.

A controller should be called from other controllers, or web requests.

Answer 2

If you want to use the same code which is written in a controller action somewhere, I think the better option is to have a C# Class in Business layer and then use the same functionality re-used where-ever needed. In controller action method too have a that class instantiated and call the particular function invoked.

public class BAL.A
{
public void Method(){
/*Implementation here. */
}
}


using BAL;

Public Class HomeCOntroller{


public void Index(){

A objA=new A();
objA.Method();
}
}

I hope this will help to re-use the functionality.
