Json JavaScriptSerializer C# 中的序列化

Question

我在 C# 中的应用程序中有对象，我需要将其序列化为 JSON，但我需要自定义结果 json 如下所示：

My class : 
 public class OrderStatus
    {
        public string title { get; set; }
        public int statusNo { get; set; }
        public string description { get; set; }
        public string message { get; set; }
        public string icon { get; set; }
    }

我需要将其转换为

{
      "1": {
        "icon": "orange_warning",
        "title": "Pending Processing",
        "message":
          "We are processing your payment on our end which could take up to 30 minutes",
        "description":
          "Feel free to continue shopping while we process your payment. You can check the status of your order in Order History at any time."
      },
      "2": {
        "icon": "done_success",
        "title": "Order Successfully Placed",
        "message": "",
        "description":
          "We have sent an email to your email address confirming your order."
      }
}

json中显示的数字是我class中的StatusNo 我用这个方法序列化了class

new JavaScriptSerializer().Serialize(model)

Answer 1

您要从中转换的结构 class 不和谐。转换的好方法是改变你的结构。为此，您可以使用 Json2csharp.com。将您的 json 结构和过去复制到其中。

多亏了我的智力，我猜你有一个 OrderStatus 的 list 并且你得到的 json 的关键是statusNo 属性你的 C# class.

要获得 JSON 的特定结构，您应该始终创建与结构匹配的 special classes 并在 class 之间进行转换es 并在最后使用默认的 JSON 序列化过程。在您的情况下，它可能看起来像这样：

public static class Program
{
    static void Main()
    {
        var orders = new List<OrderStatus>
        {
            new OrderStatus
            {
                title = "Pending Processing",
                statusNo = 1,
                description = "Feel free to continue shopping while we process your payment. You can check the status of your order in Order History at any time.",
                message = "We are processing your payment on our end which could take up to 30 minutes",
                icon= "orange_warning",
            },
            new OrderStatus
            {
                title = "Order Successfully Placed",
                statusNo = 2,
                description = "We have sent an email to your email address confirming your order.",
                message = "",
                icon= "done_success",
            },
        };

        var jsonStructure = orders
            .ToDictionary(order => order.statusNo, order => new OrderStatusJson { icon = order.icon, title = order.title, message = order.message, description = order.description });

        var json = JsonSerializer.Serialize(jsonStructure, new JsonSerializerOptions { WriteIndented = true });

        Console.WriteLine(json);
        Console.ReadLine();
    }
}

public class OrderStatusJson
{
    public string icon { get; set; }
    public string title { get; set; }
    public string message { get; set; }
    public string description { get; set; }
}

public class OrderStatus
{
    public string title { get; set; }
    public int statusNo { get; set; }
    public string description { get; set; }
    public string message { get; set; }
    public string icon { get; set; }
}

其他一些相关提示：

在 C# 端，属性名称使用 PascalCase。两种常用的 JSON 序列化程序（Newtonsoft 和 Microsoft）都可以配置为对双方使用正确的大小写。
如果需要一堆不同类型之间的映射，你应该看看 AutoMapper。
