C# Build JSON payload - List in List

Question

I have huge problems with building an JSON-payload. Hopefully, someone can give me a push in the right direction. With PostMan it's easy to CRUD-Articles, with C# i'm struggling here.

The UomUnitPrices makes me headache.

First of all, i need to do it in

• .Net35
• RestSharp 105.2.3.0
• Newtonsoft.Json 13.0.0.0

I'm struggeling with List in List's

{
    "Id": "10006",
    "Barcodes": [
        {
            "Barcode": "1010006"
        }
    ],
    "UomUnitPrices": [
        {
            "Prices": [
                {
                    "PriceLevelId": "1",
                    "PriceValue": 5.000
                }
            ]
        }
    ]
}

The payload i should create, looks like this:

{
    "Id": "10006",
    "Barcodes": [
        {
            "Barcode": "1010006"
        }
    ],
    "UomUnitPrices": [
        {
            "Prices": [
                {
                    "PriceLevelId": "1",
                    "PriceValue": 5.000
                },
                {
                    "PriceLevelId": "100",
                    "PriceValue": 20.000
                },
                {
                    "PriceLevelId": "200",
                    "PriceValue": 10.000
                },
                {
                    "PriceLevelId": "300",
                    "PriceValue": 15.000
                },
                {
                    "PriceLevelId": "400",
                    "PriceValue": 17.500
                }
            ]
        }
    ],
    "Description": "Article Description",
    "GroupAId": "50",
    "VisibilityCriteriaId": "1",
    "IsValid": true,
    "MeasureUnitId": "pcs",
    "Vat1Id": "1",
    "Vat2Id": "2"
}

All works, except the "UomUnitPrices"-List with the "Prices"-List in it.

public partial class ArticlesDTO
{
    ...
    [JsonProperty("UomUnitPrices")]
    public List<UomUnitPrice> UomUnitPrices { get; set; }
    ...
}

public partial class UomUnitPrice
{
    [JsonProperty("Prices")]
    public IList<Price> Prices { get; set; }
}

public partial class Price
{
    [JsonProperty("PriceLevelId")]
    public string PriceLevelId { get; set; }

    [JsonProperty("PriceValue")]
    public double PriceValue { get; set; }
}

public partial class ArticlesDTO
{
     public ArticlesDTO CreateArticle(string id, string description, string groupAid, bool isValid, string measureUnitId, string vat1Id, string vat2Id)
    {
        Barcode barcode = new Barcode().CreateBarcode("String Barcode");
        UomUnitPrice uomUnitPrice = new UomUnitPrice().UomUnitPriceList(); //Here i need a solution

        ArticlesDTO article = new ArticlesDTO()
        {
            Id = id,
            Description = description,
            GroupAId = groupAid,
            VisibilityCriteriaId = 1,
            IsValid = true,
            MeasureUnitId = measureUnitId,
            Vat1Id = vat1Id,
            Vat2Id = vat2Id,
            Barcodes = new List<Barcode>() { barcode },
            UomUnitPrices = new List<UomUnitPrice>() { uomUnitPrice } // That can't be that hard...
        };
        return article;
    }
    public ArticlesDTO CreateArticle(DataRow dataRow)...
}

Can somebody give me an advice how to solve that problem.

It's so humbling that I can't solve the problem myself. I watched several youtube/udemy -videos, read a lot on stackoverflow (especially this topic), but it wouldn't solve my problem.

Finally i would create the "Articles"-JSON-payload with a System.Data.DataRow. But as long as I can't even create that payload, it's going to be a long road to get there.

Any help/advice is appreciated.

Try to switch your Prices type to only List instead of IList
