c# - Cannot deserialize the current JSON array (e.g. [1,2,3]) into type

Question

I have a class like this:

public class MyStok
{
    public int STId { get; set; }
    public int SM { get; set; }
    public string CA { get; set; }
    public string Br { get; set; }
    public string BNo { get; set; }
    public decimal Vat { get; set; }
    public decimal Price { get; set; }
}

I deserialize like this:

string sc = e.ExtraParams["sc"].ToString();
MyStok myobj = JSON.Deserialize<MyStok>(sc);

My output seems to be like this (string sc) on fiddler:

[
    {
        "STId": 2,
        "CA": "hbh",
        "Br": "jhnj",
        "SM": 20,
        "Vat": 10,
        "Price": 566,
        "BNo": "1545545"
    }
]

But I get the error:

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type [...]

What is wrong in that code?

Answer 1

It looks like the string contains an array with a single MyStok object in it. If you remove square brackets from both ends of the input, you should be able to deserialize the data as a single object:

MyStok myobj = JSON.Deserialize<MyStok>(sc.Substring(1, sc.Length-2));

You could also deserialize the array into a list of MyStok objects, and take the object at index zero.

var myobjList = JSON.Deserialize<List<MyStok>>(sc);
var myObj = myobjList[0];
