C# API add LineItems to transasctionRequest

[c2w]

I am trying to pass lineItems to the transactionRequest, but I am not doing something right.  I added a snapshot of the portion of code and was hoping someone can point me in the right direction. 

Thanks in advance.

//standard api call to retrieve response
            var paymentType = new paymentType { Item = creditCard };

            var orderDetails = new orderType { invoiceNumber = "Inv 01234", description = "Test" };

            var items = new lineItemType { itemId = "TESTER", description = "Dec", name="Name", quantity = 1, taxable = false, taxableSpecified = false, unitPrice = 0.10m };
           

            var transactionRequest = new transactionRequestType
            {
                transactionType = transactionTypeEnum.authCaptureTransaction.ToString(),    // charge the card
                //amount = 133.45m,
                amount = Amount,
                payment = paymentType,
                order = orderDetails,
                lineItems = items
            };

Thanks for the reply.

I wish the online example on how to submit LineItems while using the ChargeCreditCard.cs example.  If anyone has something I can reference, it would be really helpful.

Thanks in advance.

I could also use a c# sample for adding line items. The code below causes causes controller.GetApiResponse(); to return null.

            var litem = new AuthorizeNet.Api.Contracts.V1.lineItemType

            {

                description = "DrIsOnline Encounter",

                name = cboPaymentAmount.SelectedValue,

                quantity = 1m,

                unitPrice = amt

            };

            List<AuthorizeNet.Api.Contracts.V1.lineItemType> mItems = new List<AuthorizeNet.Api.Contracts.V1.lineItemType>();

            mItems.Add(litem);

            var transactionRequest = new transactionRequestType

            {

                transactionType = transactionTypeEnum.authCaptureTransaction.ToString(),

                amount = amt,

                payment = paymentType,

                billTo = billto,

                customer = cust,

                order = m_order,

                lineItems = mItems.ToArray(),

                shipTo = mShipTo,

            };

itemId is a required field
