c# - 无法将当前 JSON 数组(例如 [1,2,3])反序列化为“System.Collections.Generic.Dictionary”类型

Question

我有第三方提供的以下 JSON 格式:

{
"data": {
    "objects": {
        "0ea73fa9333a7cbeb2d8c69a14b9970f": {
            "Id": "0ea73fa9333a7cbeb2d8c69a14b9970f",
            "Name": "test"
        },
        "38b1390ff6bc8a9837105d181000bcc8": {
            "Id": "38b1390ff6bc8a9837105d181000bcc8",
            "Name": "test"
        }
    }
}}

我正在使用这个模型反序列化:

public class ObjectTypes
{
    public ObjectTypeList data { get; set; }

    public class ObjectTypeList
    {
        public Dictionary<string, Object> objects { get; set; }
    }

    public class Object
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }
}

这工作正常，但有时 JSON 是空的，如下所示:

{
"data": {
    "objects": []
}
}

导致此异常的结果:

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'System.Collections.Generic.Dictionary`2[System.String,Models.ObjectTypes+Object]' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array. Path 'data.objects', line 1, position 20.

关于如何解决这个问题有什么建议吗？

Answer 1

您应该反序列化 ObjectTypes

类型

        public partial class ObjectTypes
        {
            [JsonProperty("data")]
            public Data Data { get; set; }
        }

        public partial class Data
        {
            [JsonProperty("objects")]
            public Dictionary<string, Object> Objects { get; set; }
        }

        public partial class Object
        {
            [JsonProperty("Id")]
            public string Id { get; set; }

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