Changing JSON variable letter case to lowercase using C#

Question

Changing JSON variable letter case to lowercase using C#

Utilizing the JSONPEncoderFactory and JSONPBehavior method has allowed me to incorporate JSONP into WCF seamlessly. Everything is set up correctly and my service successfully returns data without any issues.

However, I am faced with the challenge of converting the JSON variable names into lowercase to align with how they are utilized in JavaScript. This task has proven to be quite puzzling for me so far.

Below is an illustration of the output from my service (the elements have been altered for this demonstration)

{"Animals":["dog","cat","mouse"],"Owner":"Greg","Permanent":"y","ID":1,"DaysToStay":"1"}

It seems straightforward, right? I simply want to change "Animals" to "animals", and so forth...

Should I employ a json parser for this, or could it be achieved easily using a regular expression? I would greatly appreciate it if someone could share their approach to accomplishing this task.

Thank you!

If you want to manipulate data in JavaScript, here's a handy function for you:

convertData = function (data)
{
    var result = null;
    if (typeof(data) == "string" || typeof(data) == "number")
        return data;
    else if (data.push)
        result = [];
    else
        result = {};

    for (var key in data)
        result[String(key).toLowerCase()] = convertData(data[key]);
    return result;
};

For C# users, here's how you can deserialize a JSON string into a Dictionary:

using System.Web.Script.Serialization;
var serializer = new JavaScriptSerializer();
var dictionary = serializer.Deserialize<Dictionary<string,dynamic>>(yourJSONString);

Any complex fields will be deserialized into a Dictionary, so you'll need a recursive function to inspect the materialized dictionary.
