C# 在JObject JSON.NET中更新JArray

C# 在JObject JSON.NET中更新JArray,c#,.net,xml,json,json.net,C#,.net,Xml,Json,Json.net,我有两个文件,一个是json,另一个是xml,我需要合并这两个文件,我决定在concat/merge之后用json转换xml { "Level1": { "Level2": [ { "id": "Chart", "Box": [ { "id": "1",

我有两个文件,一个是json,另一个是xml,我需要合并这两个文件,我决定在concat/merge之后用json转换xml

{
    "Level1": {
        "Level2": [
            {
                "id": "Chart",
                "Box": [
                    {
                        "id": "1",
                        "value": "10"
                    },
                     {
                        "id": "2",
                        "value": "20"
                    }
                ]
            }
        ]
    }
}
第二个Json:

{
    "Level1": {
        "Level2": [
            {
                "id": "NameApp",
                "Box": [
                    {
                        "id": "2",
                        "value": "90"
                    },
                     {
                        "id": "3",
                        "value": "50"
                    }
                ]
            }
        ]
    }
}
输出:

{
    "Level1": {
        "Level2": [
            {
                "id": "Chart",
                "Box": [
                    {
                        "id": "1",
                        "value": "10"
                    },
                     {
                        "id": "2",
                        "value": "20"
                    }, {
                        "id": "2",
                        "value": "90"
                    },
                     {
                        "id": "3",
                        "value": "50"
                    }
                ]
            }
        ]
    }
}
XML代码:

 XmlDocument doc = new XmlDocument();

        doc.Load(pathXml);
        doc.RemoveChild(doc.FirstChild);

        string jsonTextXml = JsonConvert.SerializeXmlNode(doc);
JSON代码:

using (StreamReader readerJson = new StreamReader(pathJson))
        {
            jsonTextJson = readerJson.ReadToEnd();
        }
合并代码:

JObject o1 = JObject.Parse(jsonTextJson);

JObject o2 = JObject.Parse(jsonTextXml);

JArray box1 = o1["Level1"]["Level2"]["Box"][0] as JArray;

JArray box2 = o2["Level1"]["Level2"]["Box"][0] as JArray;

box1 = new JArray(box1.Concat(box2));

o1["Level1"]["Level2"]["Box"][0].Replace(box1);
当我想得到box1时,我有一个错误:对象引用没有设置为对象实例

我用另一种方法进行了测试

JArray box1 = o1["Level1"]["Level2"][0]["Box"] as JArray;
怎么了

最后,这是我的解决方案:

 public string joinJson(string jsonFinal, string jsonTemp)
    {

        JObject jsonMaster = JObject.Parse(jsonFinal);

        JObject jsonForMerge = JObject.Parse(jsonTemp);

        foreach (var element in jsonForMerge["Level1"]["Level2"])
        {
           string pathElement = element.Path;
           string component = pathElement.Split(new char[] { '.' }).Last();

           if (element.HasValues && !component.Equals("id"))
            {
                JArray contentTemp = jsonForMerge["Level1"]["Level2"][component] as JArray;
                JArray contentFinal = jsonMaster["Level1"]["Level2"][0][component] as JArray;

                contentFinal = new JArray(contentFinal.Concat(contentTemp));
                jsonMaster["Level1"]["Level2"][0][component].Replace(contentFinal);
            }
        }

        return jsonMaster.ToString();

    }

我建议反过来做。将json反序列化为类(这可能有帮助:)


当然,您可以将对象合并到更深的层次(将框中的每个框合并到级别2)。

如果我想在本例中得到级别2,我如何才能做到这一点?没有以这种方式工作:JArray contentK=_jsonMaster[“Level1”][“Level2”]作为JArray;
    public class Box
    {
        public string id { get; set; }
        public string value { get; set; }
    }

    public class Level2
    {
        public string id { get; set; }
        public List<Box> Box { get; set; }
    }

    public class Level1
    {
        public List<Level2> Level2 { get; set; }
    }

    public class RootObject
    {
        public Level1 Level1 { get; set; }
    }
RootObject rootObject1 = JsonConvert.DeserializeObject<RootObject>(json1);
RootObject rootObject2 = JsonConvert.DeserializeObject<RootObject>(json2);
foreach (var level in rootObject2.Level1.Level2)
{
    rootObject1.Level1.Level2.Add(level);
}

var json = JsonConvert.SerializeObject(rootObject1);
