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

AccountNumberGenerationRequest

AccountNumberGenerationRequest

AccountNameAddressRequest

AccountNameAddressRequest

UpdatePartialInformationRequest

RequestUUID

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()&nbsp; &nbsp; .OfType<JProperty>()&nbsp; &nbsp; .Where(x => x.Value is JValue)&nbsp; &nbsp; .Select(x => x.Name)&nbsp; &nbsp; .Distinct();
