本文详细介绍了如何使用C#在Web应用程序中实现级联时间选择器，并结合jQuery实现省市联动功能，包括日期选择、月份选择、天数选择以及通过省市区联动获取地址信息。

// C#级联时间
前台代码
<asp:DropDownList ID="Dyear" runat="server"
        onselectedindexchanged="Dyear_SelectedIndexChanged" AutoPostBack="true">     ///AutoPostBack="true" 很重要
    </asp:DropDownList>
    <asp:DropDownList ID="Dmonth" runat="server"
        onselectedindexchanged="Dmonth_SelectedIndexChanged" AutoPostBack="true">
    </asp:DropDownList>
    <asp:DropDownList ID="Dday" runat="server" AutoPostBack="true">
    </asp:DropDownList>
