多数のデータを含む API からの JSON 応答があります。私が実際に必要としているのは、結果の項目のほんの一部です。返された JSON のすべての項目に対応するメンバーを持つクラスを定義することなく、C# オブジェクトに逆シリアル化できる方法はありますか。それとも、返された JSON のすべてのメンバー要素に対応するプロパティを持つクラスを定義する必要がありますか?

これは、返された JSON のサンプルです。

{"status":"success","message":"Tx Fetched","data":{"txid":993106,"txref":"rgdk3viu.h","flwref":"FLW-MOCK-08efd1cb507f60ae50f7ebab4b27d234","devicefingerprint":"1d3d89c867abc0a84e1e167e2430456a","cycle":"one-time","amount":240,"currency":"NGN","chargedamount":243.36,"appfee":3.36,"merchantfee":0,"merchantbearsfee":0,"chargecode":"00","chargemessage":"Please enter the OTP sent to your mobile number 080****** and email te**@rave**.com","authmodel":"PIN","ip":"197.211.58.150","narration":"CARD Transaction ","status":"successful","vbvcode":"00","vbvmessage":"successful","authurl":"N/A","acctcode":null,"acctmessage":null,"paymenttype":"card","paymentid":"6490","fraudstatus":"ok","chargetype":"normal","createdday":0,"createddayname":"SUNDAY","createdweek":1,"createdmonth":0,"createdmonthname":"JANUARY","createdquarter":1,"createdyear":2020,"createdyearisleap":true,"createddayispublicholiday":0,"createdhour":17,"createdminute":40,"createdpmam":"pm","created":"2020-01-05T17:40:50.000Z","customerid":248784,"custphone":"080123456789","custnetworkprovider":"UNKNOWN PROVIDER","custname":"Chukwuemeka Ekeleme","custemail":"emeka.ekeleme@gmail.com","custemailprovider":"GMAIL","custcreated":"2020-01-05T17:40:50.000Z","accountid":85976,"acctbusinessname":"Learning Suite Nigeria","acctcontactperson":"Joshua Ndukwe","acctcountry":"NG","acctbearsfeeattransactiontime":0,"acctparent":1,"acctvpcmerchant":"N/A","acctalias":null,"acctisliveapproved":0,"orderref":"URF_1578246050675_7111835","paymentplan":null,"paymentpage":null,"raveref":"RV31578246049488BB4A178915","amountsettledforthistransaction":240,"card":{"expirymonth":"09","expiryyear":"22","cardBIN":"553188","last4digits":"2950","brand":" CREDIT","issuing_country":"NIGERIA NG","card_tokens":[{"embedtoken":"flw-t1nf-4542d3a9e7155f1512344b02aaa46255-m03k","shortcode":"534fb","expiry":"9999999999999"}],"type":"MASTERCARD","life_time_token":"flw-t1nf-4542d3a9e7155f1512344b02aaa46255-m03k"},"meta":[]}}

次のコードを試しました

 using (var httpClient = new HttpClient())
        {
            StringContent content = new StringContent(JsonConvert.SerializeObject(paymentVerificationRequestData), Encoding.UTF8, "application/json");

            using (var response = await httpClient.PostAsync(paymentVerificationRequestData.Url, content))
            {
                string apiResponse = await response.Content.ReadAsStringAsync();
                var paymentVerificationResponse = JsonConvert.DeserializeObject<RaveVerificationResponseData>(apiResponse);
                string msg = paymentVerificationResponse.chargemessage;

                return Content(msg);

            }
        }

ただし、chargemessage を含む paymentVerificationResponse のすべての要素はすべて null または 0 です。

私のアプリケーションは ASP.Net-Core 3.1 で実行されています

Json のすべてのプロパティに対応するクラスを用意する必要はありません。必要なプロパティのみを含むクラスを作成し、それを逆シリアル化できます。

public class Result
{
    public string Status { get; set;}
    public string Message { get; set;}
}

var result = JsonConvert.DeserializeObject<Result>(json);
