我用下面的code上传文件

I am using the following code to upload the file

   <ContentTemplate>

    <asp:FileUpload runat="server" ID="fuImage1" />

    <asp:Button runat="server" ID="btnUpload1" Text="Upload" 
                               onclick="btnUpload1_Click" />
    <asp:ImageButton ID="btnGetImage1" ImageUrl="images/cam.png" Height="25px" 
                        Width="25px" runat="server" onclick="btnGetImage1_Click" />    
    </ContentTemplate>
