Web API Post从json.stringify获取相关数据

Question

I have an html page with a button on it. Here are the functions that are important:

function updateClick() {
    SOP10100 = new Object();
    SOP10100.CUSTNMBR = "5000";
    SOP10100.SHIPMTHD = "FedEX";
    SOP10100.SOP10200 = [{ itemnmbr: "120604", quantity: 3, unitprice: .98, uofm: "ROLL" }, { itemnmbr: "120604", quantity: 1, unitprice: 4.98, uofm: "6 ROLL" }, { itemnmbr: "120604", quantity: 2, unitprice: 10.98, uofm: "12 ROLL" }]

    salesOrderCreate(SOP10100);
}

function salesOrderCreate(sOP10100) {
   $.ajax({
        url: '/api/SOP10100',
        type: 'POST',
        contentType: "application/json;charset=utf-8",
        data: JSON.stringify(sOP10100),
        success: function (data) {
            salesOrderSuccess(data);
        },
        error: function (request, message, error) {
            handleException(request, message, error);
        }
    });
}

Here is the controller that handles the click:

' POST: api/SOP10100
<ResponseType(GetType(SOP10100))>
Function PostSOP10100(ByVal sOP10100 As SOP10100) As IHttpActionResult
    If Not ModelState.IsValid Then
        Return BadRequest(ModelState)
    End If

    Try

'create the document header Dim otaSOPHdrIvcInsert As New Serialization.taSopHdrIvcInsert

        'populate the header
        With otaSOPHdrIvcInsert
            .DOCID = "EQ SALE ORD"
            .BACHNUMB = "webOrder"
            .LOCNCODE = "WAREHOUSE"
            .DOCDATE = DateString 'Today
            .CUSTNMBR = sOP10100.CUSTNMBR
            .SHIPMTHD = sOP10100.SHIPMTHD
            .REFRENCE = sOP10100.REFRENCE
    End With

Here is where I'm stuck. I need to loop through the SOP10200 (which are the order lines) and for each one do something like this:

Dim otaSOPLineIvcInsert As New Serialization.taSopLineIvcInsert_ItemsTaSopLineIvcInsert

With otaSOPLineIvcInsert
    .SOPNUMBE = strSopNumber
    .SOPTYPE = 2
    .DOCDATE = DateString
    .ITEMNMBR = sOP10100.SOP10200.itemnmbr
End With

But I can't seem to be able to get to the itemnmbr in code. I can see it when debugging, so I know it is there.

If this wasn't coming from an API but a linq query I would do a query and then

For Each IV00101 In query

Any help on this would be greatly appreciated. I know the code is in VB, but the problem also applies to C#.

Answer 1

You need to access the collection property SOP10200 to get access to it's items:

 For Each IV00101 IN sOP10100.SOP10200

      'Do Work
