C# 泛型列表到 Json 嵌套对象



我想知道如何使用 C# 将 C# 泛型列表导出到使用嵌套对象的 JSON 对象中,而不是 Json 数组。

我想生成的 Json 应该如下所示:

{
  "sales_invoice": {
    "contact_id": 201171400939013415,
    "remove_invoice_sequence_id": true,
    "invoice_sequence_id": "F2017004",
    "reference": null,
    "invoice_date": "5-1-2017",
    "currency": "EUR",
    "prices_are_incl_tax": false,
    "details_attributes": {
      "0": {
        "description": "Product description",
        "price": 13.80,
        "amount": "10",
        "tax_rate_id": 197923875808347751,
        "ledger_account_id": 197923875101607508
      },
      "1": {
        "description": "Product description",
        "price": 13.80,
        "amount": "10",
        "tax_rate_id": 197923875808347751,
        "ledger_account_id": 197923875101607508
      }
    }
  }
}

这是我的 C# 类,包括 Json 属性:

 [JsonObject(Title = "sales_invoice")]
    public class SalesInvoice
    {
        [JsonProperty("contact_id")]
        public long ContactId { get; set; }
        [JsonProperty("remove_invoice_sequence_id")]
        public bool RemoveInvoiceSequenceId { get; set; }
        [JsonProperty("invoice_sequence_id")]
        public string InvoiceSequenceId { get; set; }
        [JsonProperty("reference")]
        public string Reference { get; set; }
        [JsonProperty("invoice_date")]
        public string InvoiceDate { get; set; }
        [JsonProperty("currency")]
        public string Currency { get; set; }

        [JsonProperty("prices_are_incl_tax")]
        public bool PricesAreIncludingTax { get; set; }

        [JsonProperty("details_attributes")]
        public List<SalesInvoiceDetails> Details { get; set; }
    }
    public class SalesInvoiceDetails
    {
        [JsonProperty("0")]
        public SalesInvoiceDetailAttributes SalesInvoiceDetail { get; set; }
    }
    public class SalesInvoiceDetailAttributes
    {
        [JsonProperty("description")]
        public string Description { get; set; }

        [JsonProperty("price")]
        public decimal Price { get; set; }

        [JsonProperty("amount")]
        public string Amount { get; set; }

        [JsonProperty("tax_rate_id")]
        public long TaxRateId { get; set; }

        [JsonProperty("ledger_account_id")]
        public long LedgerAccountId { get; set; }
    }

那么,如何让这个"0"和"1"对象动态化呢?现在我得到一个结果,所有对象都有"0"。

提前感谢!

此属性:

[JsonProperty("details_attributes")]
public List<SalesInvoiceDetails> Details { get; set; }

应该是Dictionary<string, SalesInvoiceDetailAttributes>而不是List<SalesInvoiceDetails>

您的SalesInvoiceDetails类对于您想要的结构是多余的,应将其删除。

当您添加到此字典时,您将在此处增加密钥:

someObject.Details.Add("0", new SalesInvoiceDetailAttributes());
someObject.Details.Add("1", new SalesInvoiceDetailAttributes());
//etc

当它被序列化时,你的 json 将完全按照你想要的样子。
