C# Create New T()

You can see what I’m trying (but failing) to do with the following code:

protected T GetObject()
{
    return new T();
}

Any help would be greatly appreciated.

EDIT:

The context was as follows. I was playing around with a custom controller class for all controllers to derive from, with standardised methods. So in context, I needed to create a new instance of the object of the controller type. So at time of writing, it was something like:

public class GenericController<T> : Controller
{
    ...

    protected T GetObject()
    {
        return (T)Activator.CreateInstance(ObjectType);
    }        

    public ActionResult Create()
    {
        var obj = GetObject()

        return View(obj);
    }

And so I decided reflection was easiest here. I agree that, certainly given the initial statement of the question, the most appropriate answer to mark as correct was the one using the new() constraint. I have fixed that up.
