How to convert an object to a wrapper object in Ninject & C#?

Question

I have wrapper classes for some 3rd party classes without interfaces, and I need to reference it in a fairly SOLID block of C# code.

At present, I have a static function to convert the instance into a wrapper instance.

Example Code.

class A
{
    public string Name;
}

interface IAWrapper
{
    string Name { get; set; }
}

class AWrapper : IAWrapper
{
    private A Instance;
    public AWrapper(A instance)
    {
        Instance = instance;
    }
    public string Name
    {
        get
        {
            return Instance.Name;
        }
        set
        {
            Instance.Name = value;
        }
    }
}

I want a function like

var a = new A() {Name = "bob"};
var wrapped = kernel.wrap<IAWrapper>(a);

Where wrapped will be an instance of AWrapper, and it was passed a for Instance

Does Ninject possess a way to do this? To request a wrapper class interface, the instance to be wrapped, and get back the wrapped class?

(my apologies, I'm sure there are much more clear ways to ask this, but if I knew how to ask it better, I might know the answer as well. :) )

Answer 1

Assuming that the kernel was already bound you can use ConstructorArgument to specify constructor arguments. The name of the constructor parameter is the first argument of the class.

var a = new A() { Name = "bob" };
var instance = new Ninject.Parameters.ConstructorArgument("instance", a);
var wrapper = kernel.Get<IAWrapper>(instance);

Where wrapped will be an instance of AWrapper, and it was passed a for instance parameter in the constructor.
