Parse string with square brackets to json

Question

I would like to parse this string to Json:

String str="[{\"property\":\"insert_date\",\"direction\":\"ASC\"}]"

I have tried with this:

dynamic myObject=Newtonsoft.Json.JsonConvert.DeserializeObject(str)

but it returns some JArray. I would like to read values simple like:

String dir=myObject.direction;

One option is to parse string and remove square object from string. Than it would work. But i would like to do it on more proper way.

str contains a valid json which upon deserialization will obviously give you array and that's proper. If you want it as single object then you must remove square brackets from source json. I don't know what is going on in your mind. You have already done what you need to, and that is also proper. — Nikhil Vartak

if it is always single object, try to replace [ and ] and check. — Bharadwaj

If I try myobject[0].direction, i get this: A first chance exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in Microsoft.CSharp.dll I have found out, It works this way: dynamic myObject = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<List<object>>(str); Replacing [ and ] would work but i didn't want to parse string as i have described. — Simon

One way is to create a class and deserialize it as a List<ThatClass>.

For example:

public class Foo
{
    [JsonProperty("property")]
    public string Property { get; set; }
    [JsonProperty("direction")]
    public string Direction { get; set; }
}

and use it like this:

var foos = JsonConvert.DeserializeObject<List<Foo>>(str);
var foo = foos.First();
Console.WriteLine(foo.Direction);

The other way is using dynamic, and simply accessing the first element of the JArray:

String str = "[{\"property\":\"insert_date\",\"direction\":\"ASC\"}]";
dynamic objects = JsonConvert.DeserializeObject<dynamic>(str);
Console.WriteLine(objects[0].direction);

Well I suppose you simply need to do this:

String dir = myobject[0].direction;

It could be the best option I think
