How to create a Json object in Asp.net mvc 3 controller?

Question

1. How would you create this Json object from my ASP.Net MVC 3 Controller ?

2. Newbie in Json, in this Json object notation, can I replace the [ and ] sign with { and }?

   var data = [ { label: 'node1', children: [ { label: 'child1' }, { label: 'child2' } ] }, { label: 'node2', children: [ { label: 'child3' } ] } ]; 

Thanks

Answer 1

you have the JavascriptSerializer object in .NET which can serialize most types

see:

http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx

and no you can't replace [ with { (obviously you can but almost all desrializers of JSON apart from something you wrote yourself wouldn't then understand the data)

You can use Newtonsoft dll to serialize and deserialize JSON object. Please find details below.

To create JSON object you need to add Newtonsoft.Json dll and following code.

 string responseRGCDTO = JsonConvert.SerializeObject(rgcDTO);
