Netsuite 批票据-提交Id

我需要从netsuite获取对象的批账单提交id（来自不同的供应商）。有人知道怎么做吗

 TransactionSearchBasic transSearch = new TransactionSearchBasic();    
            SearchResult resVendorBill = service.search(transSearch);
            resVendorBill.pageSize = 25;
            resVendorBill.pageSizeSpecified = true;
            resVendorBill.totalRecords = SearchRecentTransCount;
            resVendorBill.totalRecordsSpecified = true;



            transSearch.recordType = new SearchStringField() { @operator = SearchStringFieldOperator.@is, searchValue = "vendorpayment", operatorSpecified = true };
            SearchResult resVendorPayment = service.search(transSearch);

            if (resVendorPayment.status.isSuccess)
            {
                Record[] searchPaymentRecords = resVendorPayment.recordList;
                if (searchPaymentRecords != null && searchPaymentRecords.Length >= 1)
                {
                    List<VendorPayment> lstVendorPayments = searchPaymentRecords.Select(ep => (VendorPayment)ep).OrderByDescending(epo => epo.createdDate).Take(SearchRecentTransCount).ToList();

                }
            }

TransactionSearchBasic transSearch=新建TransactionSearchBasic（）；
searchresvendorbill=service.search（transSearch）；
resVendorBill.pageSize=25；
resVendorBill.pageSizeSpecified=true；
resVendorBill.totalRecords=SearchRecentTransCount；
resVendorBill.totalRecordsSpecified=true；
transSearch.recordType=new SearchStringField（）{@operator=SearchStringFieldOperator@is，searchValue=“vendorpayment”，operator specified=true}；
SearchResult resVendorPayment=service.search（transSearch）；
if（重新销售付款状态isSuccess）
{
记录[]searchPaymentRecords=resVendorPayment.recordList；
if（searchPaymentRecords！=null&&searchPaymentRecords.Length>=1）
{
列出lstVendorPayments=searchPaymentRecords.Select（ep=>（VendorPayment）ep.OrderByDescending（epo=>epo.createdDate）.Take（SearchRecentTransCount.ToList（）；
}
}
