大家好，感謝您提前幫助我。下面的問題可能聽起來很傻，但我是一個初學者。
我有以下來自網路 api 的 json：

我需要做的是用位于復雜結構（cases.version.forms.sections.rows.fields）中的對應方的“label”鍵的值來更改“field”鍵的值。
要更改此值，“field”鍵的值必須與“guid”鍵的值一致。
最終結果應該是：
{
....
"field": "SP",
"value": "14042547"
....
}
我試圖搜索它，但我找不到任何有用的東西。
var caseInfo = JsonConvert.DeserializeObject<dynamic>(apiResponse);
JObject jObject = JObject.Parse((string)caseInfo.ToString());
var fields = jObject.Descendants().OfType<JProperty>()
.Where(prop => prop.Name.Contains("field") && prop.Value.Type == JTokenType.String).ToList();
首先我反序列化回應。之后，我創建了一個 JObject 并獲取了一個欄位串列。但是在這樣做之后，我不知道如何前進。
再次提前感謝大家，我希望我很清楚:)
uj5u.com熱心網友回復：
使用JSON Path，可以做到這一點：
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
// Read the JSON file.
var json = JObject.Parse(File.ReadAllText("input.json"));
// Extract label by GUID. Note that GUID case is inconsistent within the file, so we force upper case.
var labelByGuid = json.SelectTokens("cases.procedure.version.forms[*].sections[*].rows[*].fields[?(@.guid && @.label)]")
.ToDictionary(t => t["guid"]!.ToString().ToUpperInvariant(),
t => t["label"]!.ToString());
// Update entries.
foreach (var entry in json.SelectTokens("cases.content[?(@.field)]"))
{
var field = entry["field"]!.ToString().ToUpperInvariant();
if (!labelByGuid.TryGetValue(field, out var label))
continue;
entry["field"] = label;
}
// Write back the JSON object.
var settings = new JsonSerializerSettings { Formatting = Formatting.Indented };
var serializer = JsonSerializer.Create(settings);
await using var outputStream = File.CreateText(@"output.json");
serializer.Serialize(outputStream, json);
可在此處獲得作業演示。
