向大家介绍如何使用 ASP.NET 备份恢复 Sql Server 数据库,大家可以做个参考,也希望对大家有所帮助。  备份SqlServer数据库:
  
以下是引用片段:
  
  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(" ");
  return;
  }
  SqlCommand com = new SqlCommand(SqlStr2, con);
  com.ExecuteNonQuery();
  Response.Write(" ");
  }
  catch (Exception error)
  {
  Response.Write(error.Message);
  Response.Write(" ");
  }
  finally
  {
  con.Close();
  }
  
  还原SqlServer数据库:
  
以下是引用片段:
  
  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(" ");
  }
  catch (Exception error)
  {
  Response.Write(error.Message);
  Response.Write(" ");
  }
  finally
  {
  con.Close();
  }
