![ASP.NET下备份与还原数据库代码](/upload/InfoBanner/zyjiaocheng/381/6e5b0847f1774fd6b41864b980b7266b.jpg)
代码如下:
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'";
1.前台
代码如下:
<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>
<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>
</tr>
<tr>
<td colspan="3"><asp:Button ID="Button1" runat="server" Font-Size="9pt" OnClick="Button1_Click" Text="备份数据库" /></td>
</tr>
</table>
2.后台
代码如下:
using System.Data.SqlClient;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string SqlStr1 = "Server=(local);DataBase=master;Uid=sa;Pwd=";
string SqlStr2 = "Exec sp_helpdb";
SqlConnection con = new SqlConnection(SqlStr1);
con.Open();
SqlCommand com = new SqlCommand(SqlStr2, con);
SqlDataReader dr = com.ExecuteReader();
this.DropDownList1.DataSource = dr;
this.DropDownList1.DataTextField = "name";
this.DropDownList1.DataBind();
dr.Close();
con.Close();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
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'";
SqlConnection con = new SqlConnection(SqlStr1);
con.Open();
try
{
if (File.Exists(this.TextBox1.Text.Trim()))
{
Response.Write("<script language=javascript>alert('此文件已存在,请从新输入!');location='Default.aspx'</script>");
return;
}
SqlCommand com = new SqlCommand(SqlStr2, con);
com.ExecuteNonQuery();
Response.Write("<script language=javascript>alert('备份数据成功!');location='Default.aspx'</script>");
}
catch (Exception error)
{
Response.Write(error.Message);
Response.Write("<script language=javascript>alert('备份数据失败!')</script>");
}
finally
{
con.Close();
}
}
}
还原SqlServer
核心技术:
代码如下:
string SqlStr1 = "Server=(local);database='" + this.DropDownList1.SelectedValue + "';Uid=sa;Pwd=";
string SqlStr2 = "use master restore database " + dbname + " from disk='" + path + "'";
1.前台
代码如下:
<table>
<tr>
<td style="width: 100px; height: 21px"><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; height: 21px"></td>
</tr>
<tr>
<td style="width: 100px"><span style="font-size: 9pt">操 作 数 据 库</span></td>
<td style="width: 100px"><asp:FileUpload ID="FileUpload1" runat="server" Font-Size="9pt" Width="190px" /></td>
<td style="width: 100px">
</td>
</tr>
<tr>
<td colspan="3"><asp:Button ID="Button1" runat="server" Font-Size="9pt" OnClick="Button1_Click" Text="还原数据库" /></td>
</tr>
</table>
2.后台
代码如下:
using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)

this.DropDownList1.DataBind();
dr.Close();
con.Close();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
string path = this.FileUpload1.PostedFile.FileName; //获得备份路径及数据库名称
string dbname = this.DropDownList1.SelectedValue;
string SqlStr1 = "Server=(local);database='" + this.DropDownList1.SelectedValue + "';Uid=sa;Pwd=";
