Test for valid JSON in .NET

Is there a way in .NET that I can test if a JSON string I am about to send back to the client is valid? I am using an ASHX handler that accepts a bunch of form variables and returns a chunk of JSON that gets interpreted by the client. One of the parameters in the JSON contains a block of html that despite encoding sometimes gets corrupted with characters that cause a JSON error on the client. I'd like to catch this before it goes and email the sys admin with the details.

Additional info:

Target Framework 4.0

.ajax JQuery method used to send and read the response.

You could try to deserialize it using the DataContractJsonSerializer class.

Well, one idea is to try deserializing it server side (with your JSON framework of choice, be it Newtonsoft.Json or JsonFx) before sending it to the client.

I would use Json.NET and have something like JObject.Parse(json) in a try/catch block
