核心技术：
using;System.Data.SqlClient;
using;System.IO;
string;SqlStr1;=;"Server=(local);DataBase=master;Uid=sa;Pwd=";
string;SqlStr2;=;"Exec;sp_helpdb";
string;SqlStr1;=;"Server=(local);database='";+;this.DropDownList1.SelectedValue;+;"';Uid=sa;Pwd=";
string;SqlStr2;=;"backup;database;";+;this.DropDownList1.SelectedValue;+;";to;disk='";+;this.TextBox1.Text.Trim();+;".bak'";

<table>
<tr>
<td;style="width:;100px"><span;style="font-size:;9pt">操;作;数;据;库</span></td>
<td><asp:DropDownList;ID="DropDownList1";runat="server";Font-Size="9pt";Width="124px"></asp:DropDownList></td>
<td;style="width:;100px"></td>

<tr>
<td;style="width:;100px"><span;style="font-size:;9pt">备份名称和位置</span></td>
<td;style="width:;100px"><asp:TextBox;ID="TextBox1";runat="server";Font-Size="9pt";Width="117px"></asp:TextBox></td>
<td;style="width:;100px"><span;style="font-size:;9pt;;color:;#ff3300">（如D:/beifen）</span></td>
