EF 6动态创建内部联接

Question

我正在使用Entity框架6。 我需要传入两个表名并创建一个LINQ查询，我将能够使用它来填充Kendo数据源。

这是我目前正在尝试更改为动态的代码。

var entryPoint = (from pd in db.Employees
                              join od in db.MessageEmployees on pd.EmpID equals od.EmployeeID into t
                              from rt in t.DefaultIfEmpty()
                              where pd.Class == clssID && pd.IsInactive == 0
                              orderby pd.Class
                              select new
                              {
                                  ClassID = pd.Class,
                                  pd.FirstName,
                                  pd.LastName,
                                  pd.EmpID,
                                  pd.EmployeeID,
                                  EmpMessageID = rt.EmployeeID
                              });
            //IQueryable<Employee> emps = db.Employees;
            DataSourceResult result = entryPoint.ToDataSourceResult(request, empl => new HierachyEmployee
            {
                ClassID = empl.ClassID,
                FirstName = empl.FirstName,
                LastName = empl.LastName,
                EmpID = empl.EmpID,
                IsChecked = empl.EmpMessageID != null
            });
            return Json(result);

我需要db.MessageEmployees和db.Employees是动态的。提前感谢您的帮助。
