分隔包含对象的JSON字符串 [英] Separating a JSON string that contains object

问题描述

我有一个包含数组的JSON字符串，无法将其反序列化.我想拆分一下，以便每次尝试崩溃时都可以访问产品列表及其代码和数量.返回Json字符串，如下所示:

I have a JSON string that contains an array and it is unable to be deserialized. I would like to split so that I can access a list of products and their codes and quantities, each time I try it crashes. The Json string is returned like so:

{
  "transaction_id": "88",
  "store_id": "3",
  "cashier_id": null,
  "loyalty_account": null,
  "transaction_time": "1382027452",
  "total_amount": "99.45",
  "items": {
    "1239219274": "1",
    "3929384913": "1"
  },
  "payments": {
    "cc": "99.45"
  }
}

我希望将其分为以下部分:

I would like it to be separate it into:

{
  "transaction_id": "88",
  "store_id": "3",
  "cashier_id": null,
  "loyalty_account": null,
  "transaction_time": "1382027452",
  "total_amount": "99.45"
}

和

{
  "1239219274":"1",
  "3929384913":"1"
}

和

{
  "cc": "99.45"
}

这不是JSON数组，而是一个JSON对象，它基本上是值的字典.

That is not a JSON array, that is a JSON object which is basically a dictionary of values.

JSON数组如下所示用方括号 [] 进行序列化:

A JSON array is serialized like the following with square brackets [ ]:

{
    "name":"Outer Object",
    "items": [
        {
            "name":"Item #1"
        },
        {
            "name":"Item #2"
        },
        {
            "name":"Item #3"
        }
    ]
}

您可能应该花几分钟学习 Json.NET ，它将处理有关以下内容的详细信息你.

You should probably just spend a few minutes learning Json.NET which will take care of the details for you.

这是我可以将该字符串反序列化为对象的方法:

Here's how I can deserialize that string to an object:

public class Transaction
{
    [JsonProperty("transaction_id")]
    public int Id { get; set; }

    [JsonProperty("store_id")]
    public int StoreId { get; set; }

    [JsonProperty("cashier_id")]
    public int? CashierId { get; set; }

    [JsonProperty("loyalty_account")]
    public string LoyaltyAccount { get; set; }

    [JsonProperty("transaction_time")]
    public int TransactionTime { get; set; }

    [JsonProperty("total_amount")]
    public decimal TotalAmount { get; set; }

    [JsonProperty("items")]
    public Dictionary<string, string> Items { get; set; }

    [JsonProperty("payments")]
    public Dictionary<string, string> Payments { get; set; }
}

然后我可以简单地写:

Transaction transaction = JsonConvert.DeserializeObject<Transaction>(json);
