<asp:DropDownList ID="DropDownList1" runat="server" Height="16px" Width="66px">
<asp:ListItem>select</asp:ListItem>
<asp:ListItem>http://www.codeproject.com/Questions/383971/DropdownBox-Selted-item-To-NaviGated-Url</asp:ListItem>
<asp:ListItem>http://www.google.co.in/</asp:ListItem>
</asp:DropDownList>
<br />
<br />
<br />
<asp:Button ID="Button3" runat="server" Text="Button" />
</div>
在CS页面中:
In CS Page:

Response.Redirect(DropDownList1.SelectedItem.Text)
End Sub
