问题
With the following code I want to create multiple line items to show up in a new invoice.
How do I create multiple line items in my invoice, corresponding to my multiple order items from my custom application?
Running the following code with OrderItems having 4 items in order shows only one item in the invoice. Price and name is correct but number of products are not. Only one shows up.
I believe this line is the correct line to add line items. But does it actually add line item(s)?
invoice.Line = new Line[] { invoiceLine };
Code
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 };
}

回答1:
Currently every time the loop executes this line
invoice.Line = new Line[] { invoiceLine };
it is overwriting the previous value by assigning a new array. There will always be one item in the array once there are order items based on your current code.
Either store the lines in a list and then convert to an array after processing all the order items.
var orderItems = order.OrderItems;
var lines = new List<Line>();
foreach (var orderItem in orderItems) {
//Line
Line invoiceLine = new Line();
//...code removed for brevity
lines.Add(invoiceLine);
}
//Assign Line Items to Invoice
invoice.Line = lines.ToArray();
Or the other option would be to create the array before and populate it as the line items are created.
var orderItems = order.OrderItems;
var lineCount = orderItems.Count();
//Creating Line array before
invoice.Line = new Line[lineCount];
for (int index = 0; index < lineCount; index++) {
//Order item
var orderItem = orderItems[index];
//Line
Line invoiceLine = new Line();
//...code removed for brevity
//Assign Line Item to Invoice
invoice.Line[index] = invoiceLine;
}
UPDATE:
Get the item reference and set the necessary values
var itemRef = itemRepository.Get(i => i.ItemID == orderItem.ItemID).FirstOrDefault();
if (itemRef != null) {
//Line Sales Item Line Detail - ItemRef
lineSalesItemLineDetail.ItemRef = new ReferenceType() {
Name = itemRef.FullDescription,
Value = itemRef.ItemID
};
}
