使用Jayrock将JSON格式化String转换为JsonObject

Question

I have a request parameter in my ASP.NET app. that is in JSON format, and I was wondering if there is a good (quick and easy) way to convert a JSON string to a Jayrocks JsonObject, so I can easily extract key-value pairs without the need to manually parse the string?

Answer 1

Assuming json is the variable containing JSON text, use Jayrock.Json.Conversion.JsonConvert.Import(json) . What you will get back in return is either a JsonObject , JsonArray , JsonNumber , System.String , System.Boolean or a null reference depending on the root JSON value in the source JSON text. If you know it is going to be a JSON object for sure then you can safely cast the return value or use JsonConvert.Import<JsonObject>(json) .

I would discourage working against JsonObject directly unless you particularly depend on one of its features. You should just pretend the JSON object you get back is a dictionary; either IDictionary or IDictionary<string, object> . With the latest version for .NET Framework 4, you can also work with a JsonObject as a dynamic object.

I don't know Jayrock, but if you want to accept a JSON object as a parameter of Action in MVC2 than the easiest way to do it is by using JsonValueProviderFactory from Futures assembly.

It's part of System.Web.Mvc in MVC3.
