我需要遍历下面的内容并在同一 JSON 模型中添加一组附加值来形成最终输出。请帮助我如何添加数据，因为数据包含递归。
不应修改键的顺序。最终输出应该是相同的格式。 我想将此 JSON 反序列化为一些类，更新更多数据，然后将其序列化回 JSON。我们怎样才能做到呢？
从 Json 文件中读取: 输入:
{
"id" : "abv.123",
"developName" : "ABV.123",
"pay25" : {
"0" : {
"data" : "group35",
"divison" : 0,

}
},

"divName" : "test352322",

},

"data" : "divisiondata",

} ]
},
"4" : {
"data" : "divisiondata",
"divison" : 0,
"divName" : "test1111"
},
"5" : {
"data" : "divisiondata",

}
},
"4" : {
"data" : "group35",
"divison" : 0,
"pay25" : {
"0" : {

},
"3" : {
"data" : "divisiondata",
"divison" : 0,
"divName" : "test953312644"
}
}
}
}
}
从此 JSON 中读取附加值集:
{
"name33": {
"def1": "Value 1",
"tip3": "Tip 53",
"disp3": "develop 1",
"path" : "Displayname"
},
"fab125": {
"def1": "Value 5",
"tip3": "strr11",
"disp3": "develop 2",
"path" : "Displayname"
},
"test322": {
"def1": "Value 2",
"tip3": "dev 53",
"disp3": "develop 3",
"path" : "Displayname"
},
{....},
{.....},
"test953312": {
"def1": "Value 21",
"tip3": "dev 5311",
"disp3": "develop 334",
"path" : "Displayname"
},
"test953312622": {
"def1": "Value 212",
"tip3": "dev 53222",
"disp3": "develop 22113",
"path" : "Displayname"
},
{....}
}
输出应该与两个 json 合并，而不改变数据的顺序:
最佳答案
解决方案1:
您可以使用Newtonsoft.Json的Newtonsoft.Json.Linq来篡改数据。由于您的数据不规则，因此反序列化会更加复杂。它可能不会输出额外的字段。
//deserialize
JObject jObj = JObject.Parse(jsonString);
JObject idObj = (JObject)jObj["id"];
JObject idObj0 = (JObject)idObj["0"]["id"]["0"]; // 0 can replace to N, loop can deal with it.
idObj0.add("value", "ewr");
idObj0.add("type", "bool");
//serialize
string resultJsonString = jObj.ToString();
解决方案2:
如果您更喜欢反序列化为类。您可以在.Net 5或.Net Core 3.1中使用 native 库System.Text.Json
public class Model
{
public string reports {get; set;};
public Dictionary<string, IdModel> id {get; set;};
}
public class IdModel
{
[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
public string data {get; set;}
[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
public string text {get; set;}
[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
public string name {get; set;}
[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
public string display {get; set;}
[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
public string value {get; set;}
[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
public string type {get; set;}
[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
public Dictionary<string, IdModel> id {get; set;};
}
var data = JsonSerializer.Deserialize<Model>(jsonString);
data.id["0"].id["0"].value = "ewr";
data.id["0"].id["0"].type = "bool";
.......
string resultJsonString = JsonSerializer.Serialize<Model>(data);
引用:How to serialize and deserialize (marshal and unmarshal) JSON in .NET
由于数据复杂，我会选择方案1。
这是您可以引用的代码
using Newtonsoft.Json.Linq;
var inputJObject = JObject.Parse(jsonString);
var appendDataJObject = JObject.Parse(appendDataString);
FindAndReplace(inputJObject, appendDataJObject);
string resultString = inputJObject.ToString();
public static void FindAndReplace(
JObject input,
JObject appendData,
string keyName = "pay25",
string toReplaceFieldName = "divName")
{
foreach (var targetKey in ((JObject)input[keyName]))
{
var targetJObject = (JObject)targetKey.Value;
//check whether there is pay25 property in child, if yes, search child recursively
if (targetJObject.ContainsKey(keyName))
{
FindAndReplace(targetJObject, appendData);
}
else
{
//if no, check divName property existence
if (targetJObject.ContainsKey(toReplaceFieldName))
{
string divName = (string)targetJObject[toReplaceFieldName];
//check whether there is data has key = divName
if (appendData.ContainsKey(divName))
{
//append data
foreach (var data in (JObject)appendData[divName])
{
targetJObject.Add(data.Key, data.Value);
}
}
}
}
}
}
最后我觉得是一个如何递归替换数据的问题。
