How to do this Linq2Sql join
===

Please do not give me help in lamba

    I have two tables. 
    Employees:   
    pk           
    name        

    ExpenseTeamMembers: 
    pk                        
    expMgrPk
    empPk

    Example: pk      expMgrPk     empPk     
         1         7          81
         2         7          101
         3         13         99
         4         13         22
         5         13         56

Basically the first table is a list of employees and the second is a table for keeping track of which employees belong to which manager. 

The first sql lookup works and mgr is getting me the pk of the selected name in the combo box.

What I am trying to do in the join is lookup the expMgrPk and see which employees belong to it and return their names instead of their pk. I am pretty off and need a little help. Again please do not give me help in lamba!!  Thanks
      
        private void cboManagers_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (cboManagers != null)
            {
                string selectedMgr = (string)cboManagers.SelectedValue;

                using (DataClasses1DataContext db = new DataClasses1DataContext())
                {
                    int mgr = (from f in db.employees
                              where f.name == selectedMgr
                              select f.pk).FirstOrDefault();
                   
                    var emps = (from m in db.employees
                                join t in db.expenseTeamMembers on m.pk equals t.pK
                                where t.expMgrPk == mgr
                                select m.name).ToList();
                    lstSelected.DataSource = emps;
                }
            }
        }
