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。開始吧！我有以下來自 web api 的 json。

我想要做的是重命名“欄位”鍵及其值，包含在“內容”鍵的值中，如下所示：
{
"PLANT LOCATION":"PRIVATE PROPERTY"
},
{
"TRIAL PERIOD":""
},
{
"EXECUTED BY":"JOHN DOE"
}
因此，將鍵“欄位”更改為其值，并將值“欄位”更改為“值”的值，如本例所示。
我試圖四處尋找改變鍵的方法，但得到的結果不是我想要的。
這是我的代碼：
var caseInfo = JsonConvert.DeserializeObject<dynamic>(apiResponse);
JObject jObject = JObject.Parse((string)caseInfo.ToString());
var labelByGuid = jObject.SelectTokens("cases.version.forms[*].sections[*].rows[*].fields[?(@.guid && @.label)]")
.ToDictionary(t => t["guid"]!.ToString().ToUpperInvariant(),
t => t["label"]!.ToString());
// Update entries.
foreach (var entry in jObject.SelectTokens("cases.content[?(@.field)]"))
{
var field = entry["field"]!.ToString().ToUpperInvariant();
if (!labelByGuid.TryGetValue(field, out var label))
continue;
entry["field"] = label;
//=> I added this piece of code to try to do what I said before
if (entry["value"] != null)
{
if (entry["value"].HasValues)
{
entry["field"] = entry["value"].SelectToken("Value");
}
else
{
entry["field"] = entry["value"];
}
}
else
{
entry["field"] = "";
}
//entry["field"] = label;
SetKey(jObject, entry.First, label); <=
}
public void SetKey(JObject parent, JToken token, string newKey)
{
var tokenProp = token as JProperty;
var oldKeyName = tokenProp.Name;
parent[newKey] = tokenProp.Value;
parent.Remove(oldKeyName);
}
這是我得到的結果：

最后一個問題。除此之外，我怎樣才能洗掉我不感興趣的鍵和值？或者更確切地說，我怎樣才能只獲取具有各自值“id”、“nameLower”和“content”的鍵？
再次，真的提前感謝大家，我希望我很清楚:)

我想要這個最終的json。我怎樣才能只得到這些鑰匙？
uj5u.com熱心網友回復：
試試這個
var data= JObject.Parse(json);
var content = (JArray)data["cases"]["content"];
var jObj = new JObject();
foreach (var item in content)
{
var value = item["value"] is JObject ? (string)item["value"]["Value"] : (string)item["value"];
if (jObj.ContainsKey((string)item["field"])) jObj[(string)item["field"]] = value;
else jObj.Add((string)item["field"], value);
}
var newData= new JObject();
newData["status"] = data["status"];
newData["cases"] = new JObject();
newData["cases"]["id"] = data["cases"]["_id"];
newData["cases"]["nameLower"] = data["cases"]["nameLower"];
newData["cases"]["content"] = new JArray { jObj };
var newJson = newData.ToString();
新的json
