问题描述

如何在 C# 中使用 JSON.net 反序列化 JSON，其中键值未知(它们是多个设备的 MAC 地址).可能有一个或多个键条目.

How do I deserialize JSON with JSON.net in C# where the key values are not known (they are MAC addresses of multiple devices). There could be one or more key entries.

{
    "devices":
    {
        "00-00-00-00-00-00-00-00":
        {
            "name":"xxx",
            "type":"xxx",
            "hardwareRevision":"1.0",
            "id":"00-00-00-00-00-00-00-00"
        },
        "01-01-01-01-01-01-01-01":
        {
            "name":"xxx",
            "type":"xxx",
            "hardwareRevision":"1.0",
            "id":"01-01-01-01-01-01-01-01"
        },
      }
}

推荐答案

您可以使用字典将 MAC 地址存储为键:

You can use a Dictionary to store the MAC addresses as keys:

public class Device
{
    public string Name { get; set; }
    public string Type { get; set; }
    public string HardwareRevision { get; set; }
    public string Id { get; set; }
}

public class Registry
{
    public Dictionary<string, Device> Devices { get; set; }
}

以下是反序列化示例 JSON 的方法:

Here's how you could deserialize your sample JSON:

Registry registry = JsonConvert.DeserializeObject<Registry>(json);

foreach (KeyValuePair<string, Device> pair in registry.Devices)
{
    Console.WriteLine("MAC = {0}, ID = {1}", pair.Key, pair.Value.Id);
}

输出:

MAC = 00-00-00-00-00-00-00-00, ID = 00-00-00-00-00-00-00-00
MAC = 01-01-01-01-01-01-01-01, ID = 01-01-01-01-01-01-01-01
