asp.net備份還原SQLServer實例代碼程序_.Net教程

推薦：將GridView內(nèi)容導出到Excel或Word中
前臺頁面： % @PageLanguage = C# AutoEventWireup = true CodeFile = ExportDemo.aspx.cs Inherits = ExportDemo % ! DOCTYPEhtmlPUBLIC-//W3C//DTDXHTML1.0xhtml1-transitional.dtd

主要是利用SQL Server提供的SQL語句來實現(xiàn)備份的。
備份：use master;backup database @name to disk=@path;
恢復：use master;restore database @name from disk=@path;
上面用的是參數(shù)化SQL語句，可以在程序執(zhí)行的時候動態(tài)給參數(shù)賦值。

.aspx代碼：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DatabaseAction.aspx.cs" Inherits="DatabaseAction" %>

    <tr><td colspan="2">數(shù)據(jù)庫還原和備份</td></tr>
    <tr><td>請選擇數(shù)據(jù)庫</td><td>
        <asp:DropDownList ID="ddlDatabaseList" runat="server">
        </asp:DropDownList></td></tr>
    <tr><td>
        數(shù)據(jù)庫文件名</td><td>

        <tr><td>
        操作</td><td>
             <asp:Button ID="btnOK" runat="server" OnClick="btnOK_Click" Text="執(zhí)行" /></td></tr>

分享：一個比較好看的網(wǎng)頁翻頁效果
顯示效果：12345，點擊了４后又顯示，45678并轉(zhuǎn)到第４頁，如果總共有１0頁，顯示到678910就不再顯示了。 .aspx trtdalign=centerdivclass=tbl 【當前頁:asp:LabelID=lblcurpgrunat=server/asp:Label|總記錄數(shù):asp:LabelID=lblRecordrunat=server
