protected readonly IMsgSetRequest RequestMsgSet = null;
protected IMsgSetResponse ResponseMsgSet = null;

public string GetAllCustomer(bool IsActiveOnly = true)
{

    RequestMsgSet.ClearRequests();
    ICustomerQuery CustomerQueryRq = RequestMsgSet.AppendCustomerQueryRq();

    if (IsActiveOnly)
    {
        if (CustomerQueryRq != null)
            CustomerQueryRq.ORCustomerListQuery.CustomerListFilter.ActiveStatus.SetValue(
                ENActiveStatus.asActiveOnly);
    }
    else {
        CustomerQueryRq.ORCustomerListQuery.CustomerListFilter.ActiveStatus.SetValue(ENActiveStatus.asAll);
    }
    ResponseMsgSet = SessionManager.DoRequests(RequestMsgSet);
    return(ResponseMsgSet.ToXMLString());
}

Console.WriteLine(GetAllCustomer());

它返回:

<?xml version="1.0" ?>
<QBXML>
<QBXMLMsgsRs>
<CustomerQueryRs requestID="0" statusCode="1000" statusSeverity="Error" statusMessage="There has been an internal error when processing the request." />
</QBXMLMsgsRs>
</QBXML>

我怀疑DoRequests的内存不足,因为我有11万客户。

如何重写此代码以使用较少的内存?

看一看 ICustomerQuery

您可以使用过滤来获取数据,例如:名称范围(a-i,j-r而不是s-z)过滤器、日期范围过滤器、名称以过滤器开头以及其他一些过滤器。

此外,这也可以用来只得到你想要的东西,比如: 全名和

这样可以减少内存占用。请看下面的示例代码:

public IList<CustomerModelQB> GetAllCustomer(string fromName = "a", string toName = "z", bool IsActiveOnly = true)
    {
        RequestMsgSet.ClearRequests();
        ICustomerQuery CustomerQueryRq = RequestMsgSet.AppendCustomerQueryRq();

        if (IsActiveOnly)
        {
            if (CustomerQueryRq != null)
                CustomerQueryRq.ORCustomerListQuery.CustomerListFilter.ActiveStatus.SetValue(
                    ENActiveStatus.asActiveOnly);
        }
        else
            CustomerQueryRq.ORCustomerListQuery.CustomerListFilter.ActiveStatus.SetValue(ENActiveStatus.asAll);

        //CustomerQueryRq.ORCustomerListQuery.CustomerListFilter.MaxReturned.SetValue(3);

        //Set field value for FromName
        CustomerQueryRq.ORCustomerListQuery.CustomerListFilter.ORNameFilter.NameRangeFilter.FromName.SetValue(fromName);
        //Set field value for ToName
        CustomerQueryRq.ORCustomerListQuery.CustomerListFilter.ORNameFilter.NameRangeFilter.ToName.SetValue(toName);

        CustomerQueryRq.IncludeRetElementList.Add("FullName");
        CustomerQueryRq.IncludeRetElementList.Add("AccountNumber");
        ResponseMsgSet = SessionManager.DoRequests(RequestMsgSet);
        return WalkCustomerQuery(ResponseMsgSet);
    }
