asp.net 备份和恢复数据库

观看了Insus的视频写下来的，代码可能有点冗长，如有好的想法的，可以多交流。

前台：

<form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="备份数据库" OnClick="Button1_Click" />
        <asp:Label ID="Label1" runat="server" Text=""></asp:Label>
        <asp:Label ID="Label2" runat="server" Text=""></asp:Label>
        <asp:GridView ID="gv_DataBasefile" runat="server" AutoGenerateColumns="False" Width="100%"
            OnRowCommand="gv_DataBasefile_RowCommand">
            <RowStyle HorizontalAlign="center" />
            <Columns>
                <asp:TemplateField HeaderText="文件名">
                    <ItemTemplate>
                        <%#Eval("Name") %>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="创建时间">
                    <ItemTemplate>
                        <%# objIdtu.GetDateTime( Eval("CreationTime"),"yyyy-MM-dd HH:mm:ss")%>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="修改时间">

                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="路径">
                    <ItemTemplate>
                        <%# Eval("DirectoryName")%>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="还原">
                    <ItemTemplate>
                        <%--CommandArgument 传递两个数据  Name,DirectoryName--%>
                        <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="../images/x1root.gif"
                            CommandArgument='<%# Eval("Name")+","+Eval("DirectoryName")%>' />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
