Wrap JSON data with callback function?

Question

User48651432 posted

I have a WCF service that returns a JSON object. Is there an easy way of wrapping this JSON data in parentheses and add the callback name?

I tried something like the following, but the result is surrounded by double-quotes:

Dim serializer as New JavaScriptSerializer()
Dim arrayJson as String = serializer.Serialize(myArray)

Currently, it returns this:

[
    {
        "val1": "GWh",
        "val2": 32203,
        "val3": "2008"
    },
    {
        "val1": "GWh",
        "val2": 27568,
        "val3": "2007"
    }
]

It needs to return this with the callback and the parenthesis:

callback([
    {
        "val1": "GWh",
        "val2": 32203,
        "val3": "2008"
    },
    {
        "val1": "GWh",
        "val2": 27568,
        "val3": "2007"
    }
])

I'm using VS2010 and framework 4.0.

Thanks.

Never mind, return it as a stream. This causes the "raw" mode to be used and WCF will not touch the response.

Lately, I've posted several questions that I end up answering myself. Since I assume it's because no other expert knows the answer, do I get the points?
