How to iterate over an array of dynamic type in C# 4.0?

Question

Hi I have an array of dynamic type which i want to iterate through. But when i say arrayObject.lenght, i get following error:

'object' does not contain a definition for 'length' and no extension method 'length' accepting a first argument of type 'object' could be found

how do i iterate over the array?

[Update]

I post a custom json object using jquery ajax and i have written a model binder for untyped JSON. Here is a screenshot:

Found the solution:

foreach (dynamic item in cartJsonObject)
{
   // code here
}

I was trying with for loop and foreach using var type. Changing it to dynamic solved it.
