我创建了一个xml文件，如下所示，我有一个使用linq查询获得的元素列表。
public bool createXMLFile()
{
bool myval;
try
{
var xEle = new XElement("Plist");
string path1 = AppDomain.CurrentDomain.GetData("DataDirectory").ToString();
string un = "\\" + GlobalClass.GlobalVar + "empFinance.xml";
GlobalClass.GlobalUrl = path1 + un;
xEle.Save(GlobalClass.GlobalUrl);
Debug.WriteLine("*************************************************************************");
Debug.WriteLine("Success! Converted to XML " + GlobalClass.GlobalUrl);
myval = true;
}
catch (Exception ex)
{
Debug.WriteLine("**********************************************************************");
Debug.WriteLine("EmployeeForEmpFinance exception" + ex.Message);
myval = false;
}
return myval;
}
public void BeginPayrollRunProcess(List<EmployeeEmploy> PrepList)
{
Debug.WriteLine("EmployeeFinance");
Debug.WriteLine("*****************************************************************");
var finalList = new List<EmployeeEmploy>();
var context = new SSPModel.sspEntities();
foreach (var xEle in PrepList)
{
var query = from c in context.Employee_Employ
join d in context.Employee_Financial
on c.Employee_Personal_InfoEmp_id equals d.Employee_Personal_InfoEmp_id
where d.Employee_Personal_InfoEmp_id == xEle.Employee_Personal_InfoEmp_id //&& d.Approved_on != null
select new EmployeeFinance
{
Base_Pay = d.Base_Pay,
Housing_Allowance = d.Housing_Allowance,
Base_Pay_Currency = d.Base_Pay_Currency,
Employee_Personal_InfoEmp_id = d.Employee_Personal_InfoEmp_id
};
var empfinance = query.SingleOrDefault();
if (query.Count() == 1)
{
xEle.Housing_Allowance = empfinance.Housing_Allowance.GetValueOrDefault();
xEle.Base_Pay = empfinance.Base_Pay;
xEle.Base_Pay_Currency = empfinance.Base_Pay_Currency;
xEle.Gross_Pay = xEle.Housing_Allowance.GetValueOrDefault() + xEle.Base_Pay; // suppose to get gross pay up to this point
finalList.Add(xEle);
}
}
Misc_Classes.XMLCreator wer = new Misc_Classes.XMLCreator();
bool myVal = wer.createXMLFile();
if (myVal == true)
{
insertInitialList(finalList); // method call to insert list into xml file.
}
else
{
Security.ErrorControl aa = new Security.ErrorControl();
aa.displayErrorMsg = " Creating XML";
aa.endRequest(HttpContext.Current, 2);
Security.ErrorControl.CaptureErrorMessage(0, 0, "my val return false", "BeginPayrollRunProcess", GlobalClass.GlobalVar);
return;
}
}

}
catch (Exception e){
Debug.WriteLine("********************************************************");
Debug.WriteLine("EmployeeForEmpFinance exception" + e.Message);
}
}
在最后一个方法中，我试图迭代思考我的列表（finallist）并将其插入到我的xml文件中。我收到一个错误，说我需要实例化该对象。我知道我正在使用我用于将列表插入xml文件的方法出错。欢迎一些想法。谢谢
** EDITED
在上述问题的缩短版本中..我想出来并列出下面的代码。谢谢**
public void insertInitialList(List<EmployeeEmploy> finalList)
{
Debug.WriteLine("insertInitialList" + finalList.Count());
XDocument doc = XDocument.Load(GlobalClass.GlobalUrl);
var result = from element in doc.Descendants("Plist")
select element;
foreach (var ele in result)
{
ele.Add(from a in finalList
select new XElement("EmployeeFinance",
new XElement("EmployeeEmploy_Id"),
new XElement("EmpPersonal_Id"),
new XElement("Employee_Number")));
doc.Save(GlobalClass.GlobalUrl);
}
}
