如果可以为该客户提供信用额度，那么当我尝试将Quickbooks的“应用信用”功能实施到现有发票时，我就会陷入困境。我可以通过Quickbooks Desktop UI来实现它，但是没有通过用C＃编写的.Net集成应用程序来实现它。可以请任何人指导。
我用来通过C＃代码向Quickbooks实施“申请信用”的代码。 我收到错误：“QuickBooks在解析提供的XML文本流时发现错误。”使用以下代码。
public void ApplyCreditsOnPrePayInvoices()
{
// open connection and begin session before data fetch - intentionally skipped this code
IMsgSetRequest msgset = null;
ICreditMemoQuery creditMemoQuery = null;
string sCustomerName = string.Empty;
if (this.GetConnectedToQB()) //this is the method call to login to quickbooks desktop
{
try
{
// during data fetch
msgset = m_sessionManager.CreateMsgSetRequest("US", 8, 0);
creditMemoQuery = msgset.AppendCreditMemoQueryRq();
creditMemoQuery.ORTxnQuery.TxnFilter.ORDateRangeFilter.ModifiedDateRangeFilter.FromModifiedDate.SetValue(new DateTime(2012, 3, 31), false);
IMsgSetResponse msgRes = m_sessionManager.DoRequests(msgset);
IResponseList responseList = msgRes.ResponseList;
if (responseList.Count > 0)
{
IResponse response = responseList.GetAt(0);
ICreditMemoRetList creditMemoList = response.Detail as ICreditMemoRetList;
if (creditMemoList == null)
{
return;
}
for (int i = 0; i <= creditMemoList.Count - 1; i++)
{
ICreditMemoRet qbCreditMemo = creditMemoList.GetAt(i);
if (this.GetQBCustomerListId(qbCreditMemo.CustomerRef.FullName.GetValue()) != string.Empty)
{
m_requestMsgSet.ClearRequests();
m_requestMsgSet.Attributes.OnError = ENRqOnError.roeContinue;
IInvoiceAdd invoiceAddRq = m_requestMsgSet.AppendInvoiceAddRq();
invoiceAddRq.CustomerRef.FullName.SetValue(qbCreditMemo.CustomerRef.FullName.GetValue());
ISetCredit SetCredit1 = invoiceAddRq.SetCreditList.Append();
SetCredit1.CreditTxnID.SetValue(qbCreditMemo.TxnID.GetValue());
SetCredit1.AppliedAmount.SetValue(qbCreditMemo.TotalAmount.GetValue());
IMsgSetResponse responseSetInvoice = m_sessionManager.DoRequests(m_requestMsgSet);
DataSet dsInvoice = this.GetExtractResponseFromQB(responseSetInvoice);
string sQueryResponse = Stringcl.GetValue(dsInvoice.Tables["InvoiceAddRs"].Rows[0]["statusMessage"]);
if (sQueryResponse == "Status OK")
{
Console.WriteLine("Credit no.:" + qbCreditMemo.TxnID.GetValue() + " Customer:" + qbCreditMemo.CustomerRef.FullName.GetValue() + " Total:" + qbCreditMemo.TotalAmount.GetValue());
}
}
}
}
}
catch (Exception ex)
{
string ss = ex.Message;
//handle exception here
}
finally
{
if (msgset != null)
{
Marshal.FinalReleaseComObject(msgset);
}
if (creditMemoQuery != null)
{
Marshal.FinalReleaseComObject(creditMemoQuery);
}
}
}
// end session and close connection after data fetch - intentionally skipped this code
}
提前致谢!!

我通过使用以下功能获得解决方案： -
public void ApplyCreditsOnPrePayInvoices(string sMonth, string sYear)
{
IMsgSetRequest IMsgSetRequestToQB = null;
ICreditMemoQuery ICreditMemoQueryToQB = null;
string sInvoiceTxnId = string.Empty;
string sInvoiceNumber = string.Empty;
if (this.GetConnectedToQB())
{
try
{
IMsgSetRequestToQB = m_sessionManager.CreateMsgSetRequest("US", 8, 0);
ICreditMemoQueryToQB = IMsgSetRequestToQB.AppendCreditMemoQueryRq();
ICreditMemoQueryToQB.ORTxnQuery.TxnFilter.ORDateRangeFilter.ModifiedDateRangeFilter.FromModifiedDate.SetValue(DateTimecl.GetValue("1." + sMonth + sYear), true);
IMsgSetResponse IMsgSetResponseFromQB = m_sessionManager.DoRequests(IMsgSetRequestToQB);
IResponseList ICreditListMemoAvailable = IMsgSetResponseFromQB.ResponseList;
if (ICreditListMemoAvailable.Count > 0)
{
string sCustomerListIdQB = string.Empty;
string sCustomerAccountNumber = string.Empty;
string sQBImportPrepayAccounts = Path.Combine(Environment.CurrentDirectory, sMonth + sYear, "Step11_QBImport_PrepayAccounts.csv");
DataTable dtQBImportPrepayAccounts = Utilcl.GetDataTableFromCSVFile(sQBImportPrepayAccounts);
IResponse ICreditMemoAvailable = ICreditListMemoAvailable.GetAt(0);
ICreditMemoRetList iCreditMemoList = ICreditMemoAvailable.Detail as ICreditMemoRetList;
if (iCreditMemoList != null)
{
for (int iCtr = 0; iCtr <= iCreditMemoList.Count - 1; iCtr++)
{
ICreditMemoRet ICreditMemo = iCreditMemoList.GetAt(iCtr);
DataRow[] drInvoiceNos = dtQBImportPrepayAccounts.Select("RefNumber = '" + ICreditMemo.RefNumber.GetValue() + "'");
if (drInvoiceNos.Length > 0)
{
sInvoiceNumber = Stringcl.GetValue(drInvoiceNos[0]["RefNumber"]);
m_requestMsgSet.ClearRequests();
m_requestMsgSet.Attributes.OnError = ENRqOnError.roeContinue;
IReceivePaymentAdd IReceivePayment = m_requestMsgSet.AppendReceivePaymentAddRq();
sInvoiceTxnId = this.GetQBInvoiceTxnIDList(ICreditMemo.CustomerRef.FullName.GetValue()); //To get the Transaction ID of Invoice
IReceivePayment.CustomerRef.FullName.SetValue(Stringcl.GetValue(ICreditMemo.CustomerRef.FullName.GetValue()));
IAppliedToTxnAdd IAppliedToTxnAddress = IReceivePayment.ORApplyPayment.AppliedToTxnAddList.Append();
IAppliedToTxnAddress.TxnID.SetValue(sInvoiceTxnId);
ISetCredit ISetCreditToInvoice = IAppliedToTxnAddress.SetCreditList.Append();
ISetCreditToInvoice.CreditTxnID.SetValue(ICreditMemo.TxnID.GetValue());
ISetCreditToInvoice.AppliedAmount.SetValue(ICreditMemo.TotalAmount.GetValue());
IMsgSetResponse responseApplyCredit = m_sessionManager.DoRequests(m_requestMsgSet);
DataSet dsInvoice = this.GetExtractResponseFromQB(responseApplyCredit);
string sQueryResponse = Stringcl.GetValue(dsInvoice.Tables["ReceivePaymentAddRs"].Rows[0]["statusMessage"]);
if (sQueryResponse != "Status OK")
{
Utilcl.LogMessage("QB Credit Memo Query Response: " + sQueryResponse);
}
}
}
}
}
}
catch (Exception ex)
{
Utilcl.LogMessage(ex);
}
finally
{
if (IMsgSetRequestToQB != null)
{
Marshal.FinalReleaseComObject(IMsgSetRequestToQB);
}
if (ICreditMemoQueryToQB != null)
{
Marshal.FinalReleaseComObject(ICreditMemoQueryToQB);
}
}
}
