如何用SQLDMO在ASP.NET页面下实现数据库的备份与恢复

在相应的按钮

1

<asp:Button id="wbtn_Backup" runat="server" Width="60px" Text="备 份" CssClass="Button"></asp:Button>
单击事件里调用即可：

1



/**//// <summary>
2

/// 备份按钮
3

/// </summary>
4

/// <param name="sender"></param>
5

/// <param name="e"></param>
6

private void wbtn_Backup_Click(object sender, System.EventArgs e)
7





{
8

DbOperate dbop = new DbOperate();
9

dbop.DbBackup();
10

}
