C# 反序列化 JSON 数据

Question

我有一个 JSON

{{  "action": "rma",  "devices": "[95001105,30013103,300117]",  "devandreason": [    {      "device": 95001105,      "reason": 100    },    {      "device": 30013103,      "reason": 300    },    {      "device": 300117,      "reason": 200    }  ]}}

我正在尝试获取 devandreason作为一个数组。 我尝试过创建类

public class DevReasonList
    {
        public List<DevReason> devandreason { get; set; }
    }
    public class DevReason
    {
        public Double device { get; set; }
        public Double reason { get; set; }
    }

和json_serializer :

JavaScriptSerializer json_serializer = new JavaScriptSerializer();
DevReasonList deviceAndReasonList = json_serializer.Deserialize<DevReasonList>(json.devandreason);

但它抛出异常:

json_serializer.Deserialize<DevReasonList>(json.devandreason) 'json_serializer.Deserialize<DevReasonList>(json.devandreason)' threw an exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' dynamic {Microsoft.CSharp.RuntimeBinder.RuntimeBinderException}

但我不知道我做错了什么:(

可以反序列化devandreason并使其成为一个数组？

Answer 1

这应该是您的模型

public class Devandreason
{
    public int device { get; set; }
    public int reason { get; set; }
}

public class RootObject
{
    public string action { get; set; }
    public string devices { get; set; }
    public List<Devandreason> devandreason { get; set; }
}

我删除了开头的 { 和尾随的 }，它现在验证了

{  "action": "rma",  "devices": "[95001105,30013103,300117]",  "devandreason": [    {      "device": 95001105,      "reason": 100    },    {      "device": 30013103,      "reason": 300    },    {      "device": 300117,      "reason": 200    }  ]}

编辑: 正如 @Sven 在评论中提出的:如果您的设备类型是 List，则 RootObject 会更容易遍历。

这是所需的 json，我刚刚删除了值之前的引号:

{  "action": "rma",  "devices": [95001105,30013103,300117],  "devandreason": [    {      "device": 95001105,      "reason": 100    },    {      "device": 30013103,      "reason": 300    },    {      "device": 300117,      "reason": 200    }  ]}
