我有以下代码:

public void addCustomer()
        {
            bool sessionBegun = false;
            bool connectionOpen = false;
            QBSessionManager sessionManager = null;

            try
            {
                //Create sessions manager object
                sessionManager = new QBSessionManager();

                //Create the message set request object to hold our request
                IMsgSetRequest requestMsgSet = sessionManager.CreateMsgSetRequest("US", 8, 0);
                requestMsgSet.Attributes.OnError = ENRqOnError.roeContinue;

                //Connect to quickbooks and begin a session
                sessionManager.OpenConnection("", "CSW QB Interface");
                connectionOpen = true;
                sessionManager.BeginSession(@"C:\Users\Public\Documents\Intuit\QuickBooks\Company Files\Super Legit Industries.qbw", ENOpenMode.omDontCare);
                sessionBegun = true;

                ICustomerAdd customerAddRq = requestMsgSet.AppendCustomerAddRq();
                customerAddRq.Name.SetValue("Test Customer 1");

                //Send the request and get the response from quickbooks
                IMsgSetResponse responseMsgSet = sessionManager.DoRequests(requestMsgSet);
                IResponse response = responseMsgSet.ResponseList.GetAt(0);
                ICustomerRet customerRet = (ICustomerRet)response.Detail;

                //Console.WriteLine(response.Detail.ToString());
                custID = customerRet.ListID.GetValue();

            }
            catch(Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            finally
            {
                //End the session and close the connection to quickbooks
                if(sessionBegun)
                {
                    sessionManager.EndSession();
                }
                if(connectionOpen)
                {
                    sessionManager.CloseConnection();
                }
            }
        }

我的问题是,可能存在两个人的名字相同并且需要输入快速手册的情况,但是如果我多次运行此代码(尝试多次添加“测试客户 1”),第二次我在线上抛出一个错误:

custID = customerRet.ListID.GetValue();

说:

Object reference not set to an instance of an object

有没有办法使用 QBFC 将重复的客户添加到 QB 中而不会引发异常?

我的问题是,可能会有两个人同名并需要输入快速手册的情况,

QuickBooks 本身不支持拥有两个同名客户。

您遇到的不是 QBFC、SDK 或其他任何东西的限制——这就是 QuickBooks 的工作方式。你不能有重复。
