如何在没有未知密钥的情况下访问Json数据?C#Unity3D

Question

下面是我运行该代码时的结果。我的问题是我如何访问/获取所有数据而不获取"；M4qRmfIqhKdy643Ujye"；密钥(自动生成(？我只想要{assetname，id，…etc}。我不想带上自动生成的id。

如果使用JavaScript，我可以使用object.values，但由于我使用C#，我不知道如何获取数据。

{
"-M4qRmfIqhKdy643Ujye": {
"assetName": "avatar",
"id": "-M4qRmfnFya7bC43Ujye",
"imageName": "icon_avatar",
"name": "Bob",
"objName": "Bobby",
"point": "-M4vZRY9vhKs65n5L_Gk",
"versionNumber": "3"
},
"-M4qRmfIjjd5c643Ujye": {
"assetName": "avatar",
"id": "-M4qRmfnFya7bC43Ujye",
"imageName": "icon_avatar",
"name": "Bobfds",
"objName": "Bobbydsf",
"point": "-M4vZRY9vhKs65n5L_Gk",
"versionNumber": "3"
},
"-M4qRmfIqhKdnjdsjye": {
"assetName": "avatar",
"id": "-M4qRmfnFya7bC43Ujye",
"imageName": "icon_avatar",
"name": "Bobfdsa",
"objName": "Bobbyfc",
"point": "-M4vZRY9vhKs65n5L_Gk",
"versionNumber": "3"
}
}

下面是我的下载类中的一个功能

IEnumerator DownloadData(string dataPath, Action<string> callback){
Debug.Log("dataPath=>"+dataPath);
var token = LocalData.getAuth();
Auth data = JsonUtility.FromJson<Auth>(token);
var request = new 
UnityWebRequest("https://test123.firebaseio.com/"+dataPath+".json? 
auth="+data.idToken, "GET");
request.downloadHandler = (DownloadHandler) new 
DownloadHandlerBuffer();
request.SetRequestHeader("Content-Type", "application/json");
yield return request.SendWebRequest();
if (request.isHttpError || request.isNetworkError)
{
Debug.Log(request.error);
NotificationHelper.showOnePopup("Error n"+request.error);
callback(null);
}
else
{
string json = 
FirebaseSetup.RESTToJsonConverter(request.downloadHandler.text);
callback(json);
}

下面是我的FirebaseSetup类

public static string FirebaseToJsonConverter(DataSnapshot snapshot){
string data = "[";
int i = 0;
foreach(DataSnapshot s in snapshot.Children){
data += s.GetRawJsonValue();
i++;
if(i != snapshot.ChildrenCount)
data += ",";
}
data += "]";
string JSONToParse = "{"values":" + data + "}";
return JSONToParse;
}
public static string RESTToJsonConverter(string incoming_data)
{
Debug.Log($"incoming_data:/n{incoming_data}");
var startIndex = incoming_data.IndexOf('{', incoming_data.IndexOf('{') + 1);
var endIndex = incoming_data.LastIndexOf('}') - 1;
var json = incoming_data.Substring(startIndex, endIndex - startIndex);
json = json.Trim();

Debug.Log($"json:/n{json}");
var data = JsonUtility.FromJson<string>(json);
return data;
}

这是我的错误

获取每个自动生成键的值的一种方法是将其转换为Dictionary<string, Data>。当您将其转换为字典时，您可以忽略键，只取值来执行列表中所需的操作。

例如

public class Data
{
public string assetName { get; set; }
public string id { get; set; }
public string imageName { get; set; }
public string name { get; set; }
public string objName { get; set; }
public string point { get; set; }
public string versionNumber { get; set; }
}
// in your main,
var obj = JsonConvert.DeserializeObject<Dictionary<string, Data>>(json);
List<Data> allData = obj.Select(x => x.Value).ToList();

allData将具有所有对象的列表。您可以使用Linq访问每个对象并获得所需的属性。
