Question

I’d like to create a new instance of a controller, via a string name. In classic ASP I’d do an eval, but how to do it in c#?

eg:

If I wanted to create an instance of the “AccountController, normally I’d write:

var Acc = new AccountController();

Now if the controller name is only available as a string, how could I instantiate the object?

eg,

var controllerName = "AccountController";

var acc = new eval(controllerName)();

Thank you for any help!

If your controller is within the assembly you just need a class name, otherwise you need a fully qualified name (namespace and assembly). You would do it using reflection. Something like:

Type t = Type.GetType("NameOfController");
var  c = Activator.CreateInstance(t);

There are other ways, but all involve reflection (System.Reflection).
