```
var test = {'abc':76,'data':'[6435,3310,56.06875]'}

```

how do I convert above json string to an object say:

```
class item
{
    public string abc {Get;set;}
    public float[] data {get;set}
}

```

I tried 
`JsonConvert.DeserializeObject<item>(test);`
but get this error:

```
{"Error converting value \"[6435,3310]\" to type 'System.Single[]'. Path 'data', line 1, position 117."}

```
