JSON convert dictionary to a list of key value pairs

I have a Dictionary <string, string>

If I Json.Encode this I get {"Apple":"Apples","Orange":"Oranges"}

How I can get this to:-

[{ value: "Apples", key: "Apple" }, { value: "Oranges", key: "Orange"}]

Preferably using Newtonsoft.Json or jQuery

To reiterate my comment, changing the data type from an IEnumerable> (or IDictionary) to a IList> will also cause the serialization to work "correctly" a.k.a. serialize the data as a JavaScript array. In my current situation, my JavaScript is isolated in a separate .js file where Razor can't follow so using JsonConvert.SerializeObject wasn't an option.

Definitely an odd bit of functionality here. It would be great if anyone has some insight as to why JSON serialization reacts the way by default; bug or intentional?

Convert it to a list of key value pairs before passing to the JSON serializer:

JsonConvert.SerializeObject(new List<KeyValuePair<string,string>>(dictionary));
