Does MVC3 /.net4 have a method for unpacking a JSONified Javascript array into a C# array of strings?

Question

My MVC3/.Net service is receiving some arguments as a JSONified Javascript array, and I'd like to unpack them into a C# array of strings.

Is there an existing method for doing this, or do I have to write my own?

(currently the data comes in to my controller as a single string, and looks something like this:

"[\"string1\", \"string2\", \"string3\"]"

Check for JSON.Net that helps serializing to and from the json format — Peter Aron Zentai

Why don't you create a model so that when it comes into the controller the default binder will give you an object with its properties set based upon the json data? — Jon

Yes, this should happen via built in binding but without your code to see if there's an issue, can't comment more.

See for example: ASP.Net MVC 3 - JSON Model binding to array You shouldn't require JSON.Net

The jQuery $.post method, used with the syntax in the linked question, jsonifies the object in a way that the built in binding seems to like and the rest is cake.

I originally left a comment but thought I'd jump in with an answer.

If you create a model with the properties marked as public the default binder should return you an object in your controller based upon the incoming JSON data.

public MyModel
{
  public string Value1 {get;set;}
  public string Value2 {get;set;}
  public string Value3 {get;set;}
}

public ActionResult MyActionMethod(MyModel model)
{ 
   //oooh model is populated here
}

However it looks as though your JSON data is not key/value pairs
