需要来自 Json 字符串的所有唯一键名称

Question

我在 C# 中有以下示例 json 字符串{    "AccountNumberGenerationRequest": {        "BranchNumber": 8034,        "AccountType": "041"    },    "CreateDepositAccountRequest": {        "AccountNumber": "9999999999",        "BranchNumber": 8034,        "AccountType": 41,        "WithholdingIndicator": "4"    },    "AccountNameAddressRequest": {        "AccountNumber": "9999999999",        "NameAndAddressType": 1,    },    "CustomerAccountRelationshipRequest": {        "CustomerNumber1": "58008",        "Customer1ToAccountRelationshipCode": "000"    },    "UpdatePartialInformationRequest": {        "AccountNumber": "9999999999",        "PartialInformationList": [{            "KeywordCode": "FDWTHE",            "KeywordValue": "1"        }]    },    "RequestUUID": "557d5442-8a28-4dab-b191-fe1596ddf2b8"}并且想要读取所有具有结束值的唯一键。像下面["BranchNumber","AccountType","AccountNumber","BranchNumber","AccountType","WithholdingIndicator","AccountNumber","NameAndAddressType","CustomerNumber1","Customer1ToAccountRelationshipCode","KeywordCode","KeywordValue","RequestUUID"]我正在使用以下代码var jsonSerializerSettings = new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore };        var json=  JObject.Parse(JsonConvert.SerializeObject(p, jsonSerializerSettings));        IList<string> keys = json.Properties().Select(c=> c.Name).ToList();        foreach(string key in keys)        {            Console.WriteLine(key);        }但得到只有AccountNumberGenerationRequestAccountNumberGenerationRequestAccountNameAddressRequestAccountNameAddressRequestUpdatePartialInformationRequestRequestUUID我怎样才能在 C# 中得到这个。这不是硬编码的 Json。它可以是任何 json。

您只需要展平对象并相应地过滤：

var uniqueKeys = json.Descendants()

    .OfType<JProperty>()

    .Where(x => x.Value is JValue)

    .Select(x => x.Name)

    .Distinct();
