Cannot Deserialize the Current JSON Array (E.G. [1,2,3]) into Type

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

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];

Cannot deserialize the JSON array (e.g. [1,2,3]) into type ' ' because type requires JSON object (e.g. {name:value}) to deserialize correctly

Your json string is wrapped within square brackets ([]), hence it is interpreted as array instead of single RetrieveMultipleResponse object. Therefore, you need to deserialize it to type collection of RetrieveMultipleResponse, for example :

var objResponse1 = 
    JsonConvert.DeserializeObject<List<RetrieveMultipleResponse>>(JsonStr);

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'testForApiData.States' because the type requires a JSON object

I had a brainwave not long after posting. i simply used

public object[] states { get; set; }

in the RecievedData Class. It seems to work fine now.

I think the problem you're having is that your JSON is a list of objects when it comes in and it doesnt directly relate to your root class.

var content would look something like this (i assume):

[
  {
    "id": 3636,
    "is_default": true,
    "name": "Unit",
    "quantity": 1,
    "stock": "100000.00",
    "unit_cost": "0"
  },
  {
    "id": 4592,
    "is_default": false,
    "name": "Bundle",
    "quantity": 5,
    "stock": "100000.00",
    "unit_cost": "0"
  }
]

Note: make use of http://jsonviewer.stack.hu/ to format your JSON.

So if you try the following it should work:

  public static List<RootObject> GetItems(string user, string key, Int32 tid, Int32 pid)
    {
        // Customize URL according to geo location parameters
        var url = string.Format(uniqueItemUrl, user, key, tid, pid);

        // Syncronious Consumption
        var syncClient = new WebClient();

        var content = syncClient.DownloadString(url);

        return JsonConvert.DeserializeObject<List<RootObject>>(content);

    }

You will need to then iterate if you don't wish to return a list of RootObject.

I went ahead and tested this in a Console app, worked fine.

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

Your model gets posted in its string representation, which is not JSON.

await modelContent.ReadAsStringAsync() will return a string in array-notation: [object Object].

You'll have to take care of the JSON serialization yourself.

Replace

data.append("model", { "TenantId": this.state.TenantId, "TenantUrl": this.state.TenantUrl, "TenantPassword": this.state.TenantPassword });

with

data.append("model", JSON.stringify({ "TenantId": this.state.TenantId, "TenantUrl": this.state.TenantUrl, "TenantPassword": this.state.TenantPassword }));

Cannot deserialize the current JSON object into type because the type requires a JSON array

you have several bugs in your code.Replace List<clsRaceTable> , List<clsCircuit> , List<clsLocation> with clsRaceTable,clsCircuit and clsLocation. Your classes should be

public class Root
{
    public clsMRData MRData { get; set; }
}
public class clsMRData
{
    public string xmlns { get; set; }
    public string series { get; set; }
    public string url { get; set; }
    public string limit { get; set; }
    public string offset { get; set; }
    public string total { get; set; }
    public clsRaceTable RaceTable { get; set; }
}

public class clsRaceTable
{
    public string season { get; set; }
    public List<clsRace> Races { get; set; }
}

public class clsRace
{
    public string season { get; set; }
    public string round { get; set; }
    public string url { get; set; }
    public string raceName { get; set; }
    public clsCircuit Circuit { get; set; }
    public string date { get; set; }
    public string time { get; set; }
}

public class clsCircuit
{
    public string circuitId { get; set; }
    public string url { get; set; }
    public string circuitName { get; set; }
    public clsLocation Location { get; set; }
}

public class clsLocation
{
    public string lat { get; set; }
    [JsonProperty(PropertyName = "long")]
    public string lon { get; set; }
    public string locality { get; set; }
    public string country { get; set; }
}
