Asp.net日历在页面加载事件中选择当前周

在Page_Load事件中，我希望在日历上选择当前的一周，而不仅仅是当前的一天。如何做到这一点

<asp:Calendar 
ID="Calendar1" 
runat="server" 
ondayrender="Calendar1_DayRender"   
SelectionMode="DayWeek" 
onselectionchanged="Calendar1_SelectionChanged">
</asp:Calendar>


        protected void Page_Load(object sender, EventArgs e)
    {

       Calendar1.SelectedDate = System.DateTime.Today;

    }

    protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
    {
        e.Day.IsSelectable = false;
    }

受保护的无效页面加载（对象发送方、事件参数e）
{
Calendar1.SelectedDate=System.DateTime.Today；
}
受保护的无效日历1\u DayRender（对象发送方，DayRenderReventArgs e）
{
e、 Day.IsSelectable=假；
}

尝试一下：

Calendar1.SelectionMode = CalendarSelectionMode.DayWeek;  
ArrayList selectedDates = new ArrayList();  
DateTime today = DateTime.Now;    
DateTime firstDay = today.AddDays(-(double)(today.DayOfWeek));    
for (int loop = 0; loop < 7; loop++)    
    Calendar1.SelectedDates.Add(firstDay.AddDays(loop));   

Calendar1.SelectionMode=CalendarSelectionMode.DayWeek；
ArrayList selectedDates=新建ArrayList（）；
DateTime today=DateTime.Now；
DateTime firstDay=today.AddDays（-（双倍）（today.DayOfWeek））；
for（int-loop=0；loop<7；loop++）
Calendar1.SelectedDates.Add（firstDay.AddDays（循环））；
