查了一些相關的做法,網頁在顯示時總會出現"實例為只讀",下面的做法總算是OK啦^__^ 

<asp:Calendar id="Calendar1" runat="server" Height="152px" Width="184px" Font-Names="新細明體" Font-Size="9pt"
DayNameFormat="Full">
<TodayDayStyle BackColor="#80FF80"></TodayDayStyle>
<DayStyle BackColor="#EEF6FF"></DayStyle>
<DayHeaderStyle BackColor="#D5E5F8"></DayHeaderStyle>
<TitleStyle Font-Bold="True" ForeColor="White" BackColor="#8CA5CE"></TitleStyle>
<WeekendDayStyle BackColor="#D5E5F8"></WeekendDayStyle>
</asp:Calendar>

        Dim culture As CultureInfo = New CultureInfo("zh-TW")
        culture.DateTimeFormat.AbbreviatedDayNames = arrDayNames
        Me.Calendar1.DayNameFormat = DayNameFormat.Short
        Thread.CurrentThread.CurrentCulture = culture
