linq将两个表的结果合并到一个选择新状态？

在下面的查询中，我如何更改“选择新”中没有两组字段，我希望信息进入一组没有两个字段的列，以及一个类型字段，以说明是TraineEvent还是cpd事件

    List<EmployeeCPDReportRecord> employeeCPDRecords = new List<EmployeeCPDReportRecord>();
    string employeeName;
    var q =  from cpd in pamsEntities.EmployeeCPDs
             from traineeEvent in pamsEntities.TrainingEventTrainees
             join Employee e in pamsEntities.Employees on cpd.EmployeeID equals e.emp_no
             join TrainingEventPart tEventPart in pamsEntities.TrainingEventParts on traineeEvent.TrainingEventPartId equals tEventPart.RecordId
             where (cpd.EmployeeID == id) && (startDate >= cpd.StartDate && endDate <= cpd.EndDate) &&
                    (traineeEvent.EmployeeId == id)
                    && (traineeEvent.TraineeStatus == 1 || traineeEvent.TraineeStatus == 2)
                    && (tEventPart.CPDHours > 0 || tEventPart.CPDPoints > 0)
                    && (cpd.CPDHours > 0 || cpd.CPDPoints > 0)
                   || traineeEvent.StartDate >= startDate
                    || traineeEvent.EndDate <= endDate

              orderby cpd.StartDate



             select new
                {
                    surname = e.surname,
                    forname1 = e.forename1,
                    forname2 = e.forename2,
                    EmployeeID = cpd.EmployeeID,
                    StartDate = cpd.StartDate,
                    EndDate = cpd.EndDate,
                    CPDHours = cpd.CPDHours,
                    CPDPoints = cpd.CPDPoints,
                    Description = cpd.Description,                            
                    TrainingStartDate = tEventPart.StartDate,
                    TrainingEndDate = tEventPart.EndDate,
                    TrainingCPDHours = tEventPart.CPDHours,
                    TrainingCPDPoints = tEventPart.CPDPoints,
                    TrainingEventDescription = tEventPart.Description

                };


    if (q != null)
        {
            Array.ForEach(q.ToArray(), i =>
            {

                   if (ContextBase.encryptionEnabled)
                    employeeName = ContextBase.Decrypt(i.surname) + ", " + ContextBase.Decrypt(i.forname1) + " " + ContextBase.Decrypt(i.forname2);
                else
                    employeeName = i.surname + ", " + i.forname1 + " " + i.forname2;

               if (i.TrainingStartDate !=  new DateTime(1900, 1, 1))

                   employeeCPDRecords.Add(new EmployeeCPDReportRecord(employeeName, Convert.ToDateTime(i.StartDate), Convert.ToDateTime(i.EndDate), Convert.ToDecimal(i.CPDHours), Convert.ToDecimal(i.CPDPoints), i.Description,i.t,i.EndDate,Convert.ToDecimal(i.CPDHours),Convert.ToDecimal(i.CPDPoints),i.Description,"L&D"));
               else
                   employeeCPDRecords.Add(new EmployeeCPDReportRecord(employeeName, Convert.ToDateTime(i.StartDate), Convert.ToDateTime(i.EndDate), Convert.ToDecimal(i.CPDHours), Convert.ToDecimal(i.CPDPoints), i.Description, i.StartDate, i.EndDate, Convert.ToDecimal(i.CPDHours), Convert.ToDecimal(i.CPDPoints), i.Description, "Employee CPD"));



         });
        }

List employeeCPDRecords=new List（）；
字符串employeeName；
var q=来自pamsEntities.EmployeeCPD中的cpd
来自pamsEntities中的traineeEvent.TrainingEvent受训人员
将员工e加入pamsEntities。cpd上的员工。员工ID等于e.emp_编号
在PamEntities中加入TrainingEventPart tEventPart。TrainingEventPart上的TrainingEventParts.TrainingEventPartId等于tEventPart.RecordId
其中（cpd.EmployeeID==id）和（startDate>=cpd.startDate和endDate 0 | | tEventPart.CPDPoints>0）
&&（cpd.cpd小时数>0 | | cpd.cpd点数>0）
||TraineEvent.StartDate>=开始日期
||TraineEvent.EndDate
{
if（ContextBase.encryptionEnabled）
employeeName=ContextBase.Decrypt（i.姓氏）+“，”+ContextBase.Decrypt（i.forname1）+“+ContextBase.Decrypt（i.forname2）；
其他的
employeeName=i.姓氏+”，“+i.forname1+”+i.forname2；
如果（i.TrainingStartDate！=新日期时间（1900,1,1））
添加（新员工CPDReportRecords（员工姓名、转换.ToDateTime（i.StartDate）、转换.ToDateTime（i.EndDate）、转换.ToDecimal（i.CPDHours）、转换.ToDecimal（i.CPDPoints）、i.Description、i.t、i.EndDate、转换.ToDecimal（i.CPDHours）、转换.ToDecimal（i.CPDPoints）、i.Description，“L&D”）；
其他的
employeeCPDRecords.Add（新EmployeeCPDReportRecord（employeeName，Convert.ToDateTime（i.StartDate），Convert.ToDateTime（i.EndDate），Convert.ToDecimal（i.CPDHours），Convert.ToDecimal（i.CPDPoints），i.Description，i.StartDate，i.EndDate，Convert.ToDecimal（i.CPDHours），i.Description，“员工CPD”）；
});
}

使用此代码

List<EmployeeCPDReportRecord> employeeCPDRecords = new List<EmployeeCPDReportRecord>();
