图9 调班换班管理
    调班换班信息的添加、删除、修改的业务逻辑实现如下所示：
                DAL.WorkOrder WorkObject = new DAL.WorkOrder();
                WorkObject.W_ID = BLL.BaseUtility.GenerateGUID();
                WorkObject.W_UserName = this.comboBox1.SelectedValue.ToString();
                WorkObject.W_XingMing = this.comboBox1.Text;
                WorkObject.W_Type = this.comboBox2.Text;
                WorkObject.W_Time = dateTimePicker1.Value;
                WorkObject.W_Bz = this.textBox2.Text;

                try
                {
                    _DbEntities.WorkOrder.AddObject(WorkObject);
                    _DbEntities.SaveChanges();

                    MessageBox.Show("保存成功!");

                    Clear();
                    BindDataForGridView();
                    return;
                }
                catch
                {
                    MessageBox.Show("保存失败!");
                    return;
