How to read query string in ASP.NET Core 6 MVC controller-CodePudding

I am passing a query string to my ASP.NET Core MVC web simulator:

window.location.href = "https://localhost:7064/PaymentGateWayBillDesk/HitPaymentGateWay?queryString=" data;

How to read the query string when click on the button?

public virtual async Task<IActionResult> HitPaymentGateWay(string queryString)      
{
    String[] token = queryString.Split('|');

    if (token.Length == 22) 
    {
        merchantId = token[0].ToString();
        subscriberid = token[1].ToString();
        txnReferenceNo = token[2].ToString();
        bankReferenceNo = token[3].ToString();
        txnAmount = token[4].ToString();
        totalTxnAmount = txnAmount;
        bankId = token[5].ToString();
        bankMerchantId = token[6].ToString();
        itemCode = token[9].ToString();
        txnDate = token[13].ToString();
        authStatus = token[14].ToString();
        authStatusId = 1;
        settlementType = token[15].ToString();
        RU = token[21].ToString();
    }

    var vm = new PaymentDetailsModel() 
                 {
                     ReturnUrl = RU
                 };
    return View(vm);
}
