添加到 Victors、Chili 和 Hassan 的答案。很高兴偶然发现这个问题，因为我自己正在努力解决 QBFC 的例子。
这是一套完整的代码，可能会帮助别人。如果在此期间有人可以向我指出一些有用的文档的方向......那就太好了。
将员工数据转换为 XML 字符串
public static string EmployeeListXML()
{
QBSessionManager SessionManager = new QBSessionManager();
IMsgSetRequest msgSetReq = SessionManager.CreateMsgSetRequest("US", 8, 0);
IEmployeeQuery employee = msgSetReq.AppendEmployeeQueryRq();
employee.IncludeRetElementList.Add("IsActive");
employee.IncludeRetElementList.Add("ListID");
employee.IncludeRetElementList.Add("EditSequence");
employee.IncludeRetElementList.Add("FirstName");
employee.IncludeRetElementList.Add("LastName");
employee.IncludeRetElementList.Add("SSN");
//employee.IncludeRetElementList.Add("ParentRef");
//employee.IncludeRetElementList.Add("DataExtRet"); //will return non-private and/or private data extension fields depending on the OwnerIDList, below
employee.OwnerIDList.Add("0"); // required for non-private data extn fields
//customers.OwnerIDList.Add("Your Appln GUID"); // Use this to get private data extns for the Appln identified by the GUID
SessionManager.OpenConnection2("", Application.ProductName, ENConnectionType.ctLocalQBD);
//SessionManager.BeginSession(string.Empty, ENOpenMode.omDontCare);
SessionManager.BeginSession(frmMain.QBFileName, ENOpenMode.omDontCare); // I have the filename on frmMain
IMsgSetResponse Resp = SessionManager.DoRequests(msgSetReq);
SessionManager.EndSession();
SessionManager.CloseConnection();
//MessageBox.Show(Resp.ToXMLString());
return Resp.ToXMLString();
}
将 XML 字符串放入员工对象列表中
public static List<Employee> EmployeeXMLtoList()
{
string sXML = EmployeeListXML();
List<Employee> lstEmp = new List<Employee>();
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(sXML);
XmlNodeList parentNode = xmlDoc.GetElementsByTagName("EmployeeRet");
foreach (XmlNode childNode in parentNode)
{
Employee oEmp = new Employee();
oEmp.ListID = childNode.SelectSingleNode("ListID").InnerText;
oEmp.EditSequence = childNode.SelectSingleNode("EditSequence").InnerText;
oEmp.Active = childNode.SelectSingleNode("IsActive").InnerText;
oEmp.FirstName = childNode.SelectSingleNode("FirstName").InnerText;
oEmp.LastName = childNode.SelectSingleNode("LastName").InnerText;
oEmp.SSN = childNode.SelectSingleNode("SSN").InnerText;
lstEmp.Add(oEmp);
}
return lstEmp;
}
使用 Linq 返回 Employee 对象的函数
public static Employee GetEmployeeObject(string sSSN)
{
Employee oReturn = null;
List<Employee> lstEmployee = EmployeeXMLtoList();
IEnumerable<Employee> lstEmps = from oEmp in lstEmployee
where oEmp.SSN == sSSN
select oEmp;
foreach (var oEmp in lstEmps)
{
oReturn = oEmp;
}
return oReturn;
}
代码示例
Employee oEmployee = QB.GetEmployeeObject("112-35-8560");
