    原文:http://www.cnblogs.com/cxy521/archive/2008/08/01/1258493.html

    一、备份SQL Server数据库

    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

    二、还原SQL Server数据库

    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=";
    string SqlStr2 = "use master restore database " +

    dbname + " from disk='" + path + "'";
    SqlConnection con = new SqlConnection(SqlStr1);
    con.Open();
    try
    {
    SqlCommand com = new SqlCommand(SqlStr2, con);
    com.ExecuteNonQuery();
    Response.Write("<script language=javascript>alert('还原数据成功!');

    location='Default.aspx'</script>");
    }
    catch (Exception error)
    {
    Response.Write(error.Message);
    Response.Write("<script language=javascript>alert('还原数据失败!')</script>");
    }
    finally
