C#net做sql数据库备份还原。该怎么处理

使用.net备份和还原数据库C#实现SQLSERVER2000数据库备份还原的两种方法: 方法一（不使用SQLDMO）：//////备份方法///SqlConnection conn = new SqlConnection("Server=.;Database=master;User ID=sa;Password=sa;");SqlCommand cmdBK = new SqlCommand();cmdBK.CommandType = CommandType.Text;cmdBK.Connection = conn;cmdBK.CommandText = @"backup database test to disk='C:\ba' with init";try{conn.Open();cmdBK.ExecuteNonQuery();MessageBox.Show("Backup successed.");}catch(Exception ex){MessageBox.Show(ex.Message);}finally{conn.Close();conn.Dispose();}//////还原方法///SqlConnection conn = new SqlConnection("Server=.;Database=master;User ID=sa;Password=sa;Trusted_Connection=False");conn.Open();//KILL DataBase ProcessSqlCommand cmd = new SqlCommand("SELECT spid FROM sysprocesses ,sysdatabases WHERE sysprocesses.dbid=sysdatabases.dbid AND sysdatabases.Name='test'", conn);SqlDataReader dr;dr = cmd.ExecuteReader();ArrayList list = new ArrayList();while(dr.Read()){list.Add(dr.GetInt16(0));}dr.Close();for(int i = 0; i < list.Count; i++){cmd = new SqlCommand(string.Format("KILL {0}", list), conn);cmd.ExecuteNonQuery();}SqlCommand cmdRT = new SqlCommand();cmdRT.CommandType = CommandType.Text;cmdRT.Connection = conn;cmdRT.CommandText = @"restore database test from disk='C:\ba'";try{cmdRT.ExecuteNonQuery();MessageBox.Show("Restore successed.");}catch(Exception ex){MessageBox.Show(ex.Message);}finally{conn.Close();}方法二（使用SQLDMO）：//////备份方法///SQLDMO.Backup backup = new SQLDMO.BackupClass();SQLDMO.SQLServer server = new SQLDMO.SQLServerClass();//显示进度条SQLDMO.BackupSink_PercentCompleteEventHandler progress = new SQLDMO.BackupSink_PercentCompleteEventHandler(Step);backup.PercentComplete += progress;try{server.LoginSecure = false;server.Connect(".", "sa", "sa");backup.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Database;backup.Database = "test";backup.Files = @"D:\test\myProg\backupTest";backup.BackupSetName = "test";backup.BackupSetDescription = "Backup the database of test";backup.Initialize = true;backup.SQLBackup(server);MessageBox.Show("Backup successed.");}catch(Exception ex){MessageBox.Show(ex.Message);}finally{server.DisConnect();}this.pbDB.Value = 0;//////还原方法///SQLDMO.Restore restore = new SQLDMO.RestoreClass();SQLDMO.SQLServer server = new SQLDMO.SQLServerClass();//显示进度条SQLDMO.RestoreSink_PercentCompleteEventHandler progress = new SQLDMO.RestoreSink_PercentCompleteEventHandler(Step);restore.PercentComplete += progress;//KILL DataBase ProcessSqlConnection conn = new SqlConnection("Server=.;Database=master;User ID=sa;Password=sa;Trusted_Connection=False");conn.Open();SqlCommand cmd = new SqlCommand("SELECT spid FROM sysprocesses ,sysdatabases WHERE sysprocesses.dbid=sysdatabases.dbid AND sysdatabases.Name='test'", conn);SqlDataReader dr;dr = cmd.ExecuteReader();ArrayList list = new ArrayList();while(dr.Read()){list.Add(dr.GetInt16(0));}dr.Close();for(int i = 0; i < list.Count; i++){cmd = new SqlCommand(string.Format("KILL {0}", list), conn);cmd.ExecuteNonQuery();}conn.Close();try{server.LoginSecure = false;server.Connect(".", "sa", "sa");restore.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database;restore.Database = "test";restore.Files = @"D:\test\myProg\backupTest";restore.FileNumber = 1;restore.ReplaceDatabase = true;restore.SQLRestore(server);MessageBox.Show("Restore successed.");}catch(Exception ex){MessageBox.Show(ex.Message);}finally{server.DisConnect();}this.pbDB.Value = 0;
