使用 JObject 從嵌套的 Json 獲取鍵的值

Question

我正在嘗試獲取以下 JSON 字符串的值：

{
    "PaymentStatus": [
        {
            "MerchantTxnRefNo": "277753772122780",
            "PaymentId": "20239622798237",
            "ProcessDate": "9/16/2022 8:39:00 PM",
            "StatusDescription": "Transaction Success",
            "TrackId": "20239622798237",
            "BankRefNo": "20239622798237",
            "PaymentType": "CMA",
            "ErrorCode": "0",
            "ProductType": "DBO",
            "finalStatus": "success"
        }
    ]
}

我已經使用下面的代碼來獲取它但沒有工作：

request.AddParameter("application/json", body, 
ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

var obj = response.Content;
var TransactionObj = JObject.Parse(obj);

var jObject = Newtonsoft.Json.Linq.JObject.Parse(obj);
string StatusDescription = (string)jObject["PaymentStatus"]["StatusDescription"];

有什么建議么？

Answer 1

我會嘗試這樣的

var paymentStatus = JObject.Parse(response.Content)["PaymentStatus"][0];

string statusDescription = paymentStatus["StatusDescription"].ToString();

string merchantTxnRefNo = paymentStatus["MerchantTxnRefNo"].ToString();

或者你可能需要 c# 類

List<PaymentStatus> paymentStatuses = JObject.Parse(json)["PaymentStatus"]
                                        .ToObject<List<PaymentStatus>>();

string statusDescription = paymentStatuses[0].StatusDescription;

long merchantTxnRefNo = paymentStatuses[0].MerchantTxnRefNo;

public class PaymentStatus
{
    public long MerchantTxnRefNo { get; set; }
    public long PaymentId { get; set; }
    public DateTime ProcessDate { get; set; }
    public string StatusDescription { get; set; }
    public long TrackId { get; set; }
    public long BankRefNo { get; set; }
    public string PaymentType { get; set; }
    public int ErrorCode { get; set; }
    public string ProductType { get; set; }
    public string finalStatus { get; set; }
}

Answer 2

由於 PaymentStatus 解析為數組，因此使用索引器獲取 object 如下

var StatusDescription = (string)jObject["PaymentStatus"] [0] ["MerchantTxnRefNo"];
