C# Replicate This Code - JSON with Object with JSON

Question

I'm relatively new to C# and I'm looking to replicate this following JSON expression:

{"itemData":[{"pile":"club","id":"100997087277"}]}

At present I have the following methods:

public class MoveItemValues
{
    public string pile;
    public Int64 id;
}

public class MoveItemRequestValues
{
    public MoveItemValues itemData;
}

internal string moveItem(Int64 itemId, string pile)
{
    string moveItemResponse;
    MoveItemRequestValues bodyContent = new MoveItemRequestValues();
    bodyContent.itemData = new MoveItemValues();
    bodyContent.itemData.pile = pile;
    bodyContent.itemData.id = itemId;
    string jsonContent = JsonConvert.SerializeObject(bodyContent);
    byte[] byteArray = Encoding.UTF8.GetBytes(jsonContent);
    Console.WriteLine(jsonContent);
}

This produces:

"{"itemData":{"pile":"trade","id":100997087277}}"

But as you can see the square brackets are missing.

How would I go about finishing off achieving this?

FYI the accepted style in C# is to use aliases like long instead of Int64. — juharr

itemData is an array in the json string.

FYI: You need to follow the C# naming guidelines. Property and method should be Pascal case.

public class MoveItemValues
{
    public string Pile;
    public Int64 Id;
}

public class MoveItemRequestValues
{
    public IList<MoveItemValues> ItemData;

    public MoveItemRequestValues()
    {
        ItemData = new List<MoveItemValues>();
    }
}

static void MoveItem(Int64 itemId, string pile)
{
    string moveItemResponse;
    MoveItemRequestValues bodyContent = new MoveItemRequestValues();
    bodyContent.ItemData = new List<MoveItemValues>()
    {
        new MoveItemValues {Pile = pile, Id = itemId}
    };
    var camelCaseFormatter = new JsonSerializerSettings
    {
        ContractResolver = new CamelCasePropertyNamesContractResolver()
    };
    string jsonContent = JsonConvert.SerializeObject(bodyContent, camelCaseFormatter);
    byte[] byteArray = Encoding.UTF8.GetBytes(jsonContent);
    Console.WriteLine(jsonContent);
}

static void Main(string[] args)
{
    MoveItem(100997087277, "trade");
    Console.ReadLine();
}

Won't that change the casing in the Json string as well?

I updated the answer which uses CamelCasePropertyNamesContractResolver

Very nice the only thing I would change is Int64 to long.

@juharr Thank you for pointing out the casing. I also agree on changing Int64 to long.

Thanks, and thanks for the advice on naming guidelines - always been habit to camel case in ColdFusion! Also, updated Int64 to long. Is there any particular reason why to use one rather than the other?

Use List<>

public class MoveItemRequestValues
{
    public List<MoveItemValues> itemData;
}

You should also show how the moveItem method needs to change.
