Can I receive a JavaScript Object on an API WITHOUT a Corresponding C# Object?

Question

I have a Web API 2 controller. I am sending a JavaScript Object from the client in a call:

myObject = {propertyOne: 'Hi', propertyTwo: 'Bye'}

Do I HAVE to make a class with those properties in C# to receive the object as an argument to the Web API controller?

    public void controllerMethod(myObject object)
    {

    }

Is there away to AVOID making an object that will only be used to receive data? If so, how?

Answer 1

the below would work, but not recommended.

public void controllerMethod(dynamic myObject)
    {

    }

Among a number of benefits, it's a positive security benefit to create an object and bind it so that you can't get extra properties posted in from an attacker that are not intended to be there.
