What Are Some Options To Convert Url-Encoded Form Data to JSON in .Net

Question

I have a web request that is sending the server data that is in the format application/x-www-form-urlencoded. I would like to convert it to application/json.

Example:

URL-encoded form data:

Property1=A&Property2=B&Property3%5B0%5D%5BSubProperty1%5D=a&Property3%5B0%5D%5BSubProperty2%5D=b&Property3%5B1%5D%5BSubProperty1%5D=c&Property3%5B1%5D%5BSubProperty2%5D=d 

Pretty version:

Property1=A Property2=B Property3[0][SubProperty1]=a Property3[0][SubProperty2]=b Property3[1][SubProperty1]=c Property3[1][SubProperty2]=d 

The above data needs to be converted to the following JSON data:

{     Property1: "A",     Property2: "B",     Property3: [         { SubProperty1: "a", SubProperty2: "b" },         { SubProperty1: "c", SubProperty2: "d" }] } 

Question:

Are there any free tools that are capable of doing this? I have not been able to find any myself and if they exist, I'd rather consume them than writing one myself, but if it comes to that, I will.

A C#/.Net solution is preferred.

I've written a utility class for parsing query strings and form data. It's available at:

Example:

// Example query string from the question String test="Property1=A&Property2=B&Property3%5B0%5D%5BSubProperty1%5D=a&Property3%5B0%5D%5BSubProperty2%5D=b&Property3%5B1%5D%5BSubProperty1%5D=c&Property3%5B1%5D%5BSubProperty2%5D=d"; // Convert the query string to a JSON-friendly dictionary var o=QueryStringHelper.QueryStringToDict(test); // Convert the dictionary to a JSON string using the JSON.NET // library <http://json.codeplex.com/> var json=JsonConvert.SerializeObject(o); // Output the JSON string to the console Console.WriteLine(json); 

Let me know if it works for you.
