Calendar1_SelectionChanged 事件处理程序出现错误

Question

我想从日历控件中获取选定的日期并传递给参数。

EventArgs 不包含 Start

的定义

 protected void Calendar1_SelectionChanged(object sender, System.EventArgs e)
            {
                _availebletimeSlotsRoom1 = new BindingList<string>(_allTimeSlots.ToList());
                _availebletimeSlotsRoom2 = new BindingList<string>(_allTimeSlots.ToList());
                _availebletimeSlotsRoom3 = new BindingList<string>(_allTimeSlots.ToList());
                _availebletimeSlotsRoom4 = new BindingList<string>(_allTimeSlots.ToList());
    
                DLAvailTS1.DataSource = _availebletimeSlotsRoom1;
                DLAvailTS2.DataSource = _availebletimeSlotsRoom2;
                DLAvailTS3.DataSource = _availebletimeSlotsRoom3;
                DLAvailTS4.DataSource = _availebletimeSlotsRoom4;
    
                UpdateRoom(1, e.Start, _availebletimeSlotsRoom1);  //ERROR HERE:'EventArgs' does not 
                 contain a definition for 'Start' and no extension method 'Start' accepting a first 
                 argument of type 'EventArgs' could be found (are you missing a using directive or an 
                 assembly reference?)
                UpdateRoom(2, e.Start, _availebletimeSlotsRoom2);
                UpdateRoom(3, e.Start, _availebletimeSlotsRoom3);
                UpdateRoom(4, e.Start, _availebletimeSlotsRoom4);
            }

此过程在 Calendar1 控件中的选定日期发生一些更改后开始。参数 'e' 尚未属性启动。您从 Calendar1 控件的属性读取开始日期。 Calendar1 是否控制 class MonthCalendar？然后使用属性 SelectionStart 中的值。示例：

UpdateRoom(1, Calendar1.SelectionStart, _availebletimeSlotsRoom1);
