Facebook has a new Batch request Graph API that I'm trying to consume.
The JSON looks something like this:

As you can see, the body is all that is really important, and the body is a fully escaped JSON string. In C#, is there any good ways to consume this fully escaped JSON string?
This is an example from Facebook (pulling the people who like and the comments from a post. The post that had the most comments on my feed was something political, so sorry for the ignorance in the data...) and as you can see, Unicode chars are converted to \\u0031esque, quote marks look like \\\", new-lines look like \\n, etc.
There are also escaped escaped chars, for example one of the comments in the body has \\\\" because it is the escaped escaped char (if that makes sense).
If those can be converted to their unescaped formate for normal JSON parsing, that would be the best.
Thank you!
Use Newtonsoft.Json. The library is really good for parsing and generating JSON.
There is a comment recommedning to use a Regex.Unescape().
I work with the .NET 4.5 and this method does not unescape \n and \". You probably read a response from HttpWebResponse or alike. You may want to convert it's response stream to byte array and then play a little bit with converting it to a string.
