JsonToDynamic: Consuming Json Data as Dynamic Objects in C# 4.0

About a month ago I was reading the early access edition of C# in Depth, Second Edition from Jon Skeet. In this book the auto demonstrates using dynamic objects and the dynamic keyword in C# using a wrapper around an xml document. Suppose you have a xml document containing a number of books

<book>
	<autor>The Autor</autor>
</boo>

Now you can access the auto properties of each book in the following way:

dynamic book = GetBookAsDynamic();
string autoName = book.autor

Having been using Json intensively  the last few weeks and seeing how easy it is to consume Json in JavaScript, I thought dynamic object would be a fantastic way to make Json more natural in the .Net world. My favorite Json library is the Json.Net. Since, I started to code a wrapper about it.

Suppose now you have such an object, that you have Json serialized:

var obj = new
{
    Name = "mouk",
    FavoriteNames = new[] { "mouk", "dermouk", "mouk9000" },
    NestedValues = new { First = 1, Second = 3, Nums = new[] { 1, 2, 3 } },
    NestedArray = new object[]{ 1, 3, new[] { 100, 2, 3 } },
    Age = 25,
    Height = 180
};

var serializedObject = JsonConvert.SerializeObject(obj);

After deserializing it back to a dynamic object you can access as easy as:

dynamic _deserializedObject = JsonDeserilizer.GetObjectFromString(serializedObject);

string name= _deserializedObject.Name;
int age = _deserializedObject.Age;

int nested = _deserializedObject.NestedArray[1];

    Hello,

    Nice topic , I’m wondering if you knew anything on transforming DOM objects to JSON objects?

    Regards,

    Do you mean dom objects in the browser?
    In the .Net world, you can serialize almost any object to Json using the described Json.Net library.
