converting an array in a json string into a list

Question

I have an array in a json string like this:

"TheArray": "1,2,3,4,5"

What's the best way convert this into a list of int?

Thanks.

Answer 1

string theArray = "1,2,3,4,5";

List<int> theList = (
  from string s in theArray.Split(',') 
  select Convert.ToInt32(s)
).ToList<int>();

Answer 2

Use JSON.Net or JavascriptSerializer, something like:

JArray jsonArray = JArray.Parse(jsonStr);

and then you can get out TheArray from that.

The TheArray in your question is not exactly a JSON array, so you will have to parse the string like other answers suggested after you get value of TheArray

You can use the split method:

var items = myObj.TheArray.split(',');

items[0] == "1" // true
