I want to set the Json request embedded with data tag in asp.net with c#.
After serialization,json Request
{
"RemittanceData": [
{
"Information": "TEST501"
}
],
"PaymentOrderProductId": "AHBDDA501",
"DebitAccountId": "018061058118",
"DebitCurrency": "AED",
"DebitValueDate": "20221109",
"CreditAccountId": "028676488149",
"PaymentCurrencyId": "AED",
"Amount": 10000,
"EndToEndReference": "049500130811290W20221109132539460"

Json Request Required
{
"Data": {
"RemittanceData": [
{
"Information": ""
}
],
"PaymentOrderProductId": "AHBDDA501",
"DebitAccountId": "30003198541",
"DebitCurrency": "AED",
"DebitValueDate": "20220307",
"CreditAccountId": "30000008547",
"PaymentCurrencyId": "AED",
"Amount": 1,
"EndToEndReference": "TESTDDA501"
}
}

What I have tried:

Code as below:
Class set for serialization

public class Data_501_Transact_Posting
   {
       public List<RemittanceDatum> RemittanceData { get; set; }
       public string PaymentOrderProductId { get; set; }
       public string DebitAccountId { get; set; }
       public string DebitCurrency { get; set; }
       public string DebitValueDate { get; set; }
       public string CreditAccountId { get; set; }
       public string PaymentCurrencyId { get; set; }
       public decimal Amount { get; set; }
       public string EndToEndReference { get; set; }
   }

   public class RemittanceDatum_501_Posting
   {
       public string Information { get; set; }
   }

   public class Root7
   {
       public Data_501_Transact_Posting Data { get; set; }
   }

Data_501_Transact_Posting objDataRequest = new Data_501_Transact_Posting();
                           objDataRequest.PaymentOrderProductId = Convert.ToString(ds.Tables[0].Rows[i]["PaymentOrderProductId"]);
                           objDataRequest.DebitAccountId = Convert.ToString(ds.Tables[0].Rows[i]["DebitAccountId"]);
                           objDataRequest.DebitCurrency = Convert.ToString(ds.Tables[0].Rows[i]["DebitCurrency"]);
                           DateTime dtDebitValueDate = Convert.ToDateTime(ds.Tables[0].Rows[i]["DebitValueDate"]);
                           objDataRequest.DebitValueDate = dtDebitValueDate.ToString("yyyyMMdd");
                           objDataRequest.CreditAccountId = Convert.ToString(ds.Tables[0].Rows[i]["CreditAccountId"]);
                           objDataRequest.PaymentCurrencyId = Convert.ToString(ds.Tables[0].Rows[i]["PaymentCurrencyId"]);
                           objDataRequest.Amount = Convert.ToInt32(ds.Tables[0].Rows[i]["Amount"]);
                           objDataRequest.EndToEndReference = Convert.ToString(ds.Tables[0].Rows[i]["EndToEndReference"]);


                           List<RemittanceDatum> Listdata = new List<RemittanceDatum>();
                           for (int j = 0; j < ds.Tables[1].Rows.Count; j++)
                           {
                               if (Convert.ToString(ds.Tables[0].Rows[i]["DD501TransactPostingId"]) == Convert.ToString(ds.Tables[1].Rows[j]["DD501TransactPostingId"]))
                               {
                                   Listdata.Add(new RemittanceDatum
                                   {
                                       Information = Convert.ToString(ds.Tables[1].Rows[j]["Information"])
                                   });
                               }
                           }


                           IN_501_TRANSACT_POSTING_DETAILS obj501TransactDtls = new IN_501_TRANSACT_POSTING_DETAILS();
                           obj501TransactDtls.RemittanceData = Listdata;
                           objDataRequest.RemittanceData = obj501TransactDtls.RemittanceData;

 string jsonRequest = JsonConvert.SerializeObject(objDataRequest);
