C# Quickbooks在线会计-如何在发票中添加多个行项目？

使用下面的代码，我想创建多个行项目以显示在新发票中

如何在发票中创建多个行项目，对应于自定义应用程序中的多个订单项目？

使用OrderItems（订单中有4个项目）运行以下代码时，发票中仅显示一个项目。价格和名称正确，但产品数量不正确。只有一个出现了

我相信这一行是添加行项目的正确行。但它实际上添加了行项目吗

invoice.Line=新行[]{invoiceLine}

代码

var orderItems = order.OrderItems;

foreach (var orderItem in orderItems)
{
    //Line
    Line invoiceLine = new Line();

    //Line Description
    invoiceLine.Description = itemRepository.Get(i=>i.ItemID == orderItem.ItemID).First().FullDescription;

    //Line Amount
    invoiceLine.Amount = orderItem.Price * orderItem.Quantity;
    invoiceLine.AmountSpecified = true;

    //Line Detail Type
    invoiceLine.DetailType = LineDetailTypeEnum.SalesItemLineDetail;
    invoiceLine.DetailTypeSpecified = true;

    //Line Sales Item Line Detail
    SalesItemLineDetail lineSalesItemLineDetail = new SalesItemLineDetail();

    //Line Sales Item Line Detail - ItemRef
    lineSalesItemLineDetail.ItemRef = new ReferenceType()
    {
        name = itemRepository.Get(
            i=>i.ItemID == orderItem.ItemID).First().FullDescription,
            Value = item.Id
    };

    //Line Sales Item Line Detail - UnitPrice
    lineSalesItemLineDetail.AnyIntuitObject = orderItem.Price;//33m;
    lineSalesItemLineDetail.ItemElementName = ItemChoiceType.UnitPrice;

    //Line Sales Item Line Detail - Qty
    lineSalesItemLineDetail.Qty = orderItem.Quantity;//10;
    lineSalesItemLineDetail.QtySpecified = true;

    //Line Sales Item Line Detail - TaxCodeRef
    //For US companies, this can be 'TAX' or 'NON
    lineSalesItemLineDetail.TaxCodeRef = new ReferenceType()
    {
        Value = "TAX"
    };

    //Line Sales Item Line Detail - ServiceDate 
    lineSalesItemLineDetail.ServiceDate = DateTime.Now.Date;
    lineSalesItemLineDetail.ServiceDateSpecified = true;

    //Assign Sales Item Line Detail to Line Item
    invoiceLine.AnyIntuitObject = lineSalesItemLineDetail;

    //Assign Line Item to Invoice
    invoice.Line = new Line[] { invoiceLine };

}
