ASP.NET下备份与还原数据库代码

核心技术:

  

复制代码 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

  

复制代码 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

  

复制代码 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:

  

复制代码 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

  

复制代码 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>
