使用SQLDMO操纵MS-SQL数据库

SQLDMO（SQL Distributed Management Objects，SQL分布式管理对象）是MS开发的一组COM组件。

                //取得服务器列表
        private ArrayList GetServerList()
{ 
            System.Collections.ArrayList alServers = new System.Collections.ArrayList();
            SQLDMO.Application sqlApp = new SQLDMO.ApplicationClass();
            try
{
                SQLDMO.NameList serverList = sqlApp.ListAvailableSQLServers();
                for(int i = 1; i <= serverList.Count; i++)
{
                    alServers.Add(serverList.Item(i));
                } 
            } 
            catch(Exception e) 
{ 
                throw(new Exception("取数据库服务器列表出错："+e.Message));
            } 
            finally 
{ 
                sqlApp.Quit();
            } 
            return alServers;
        }






                //获得服务器上的数据库列表
        private bool GetDbList(string strServerName,string strUserName,string strPwd) 
{
            bool bolReturn = false;
            ArrayList alDbs = new ArrayList();
            SQLDMO.Application sqlApp = new SQLDMO.ApplicationClass();
            SQLDMO.SQLServer svr = new SQLDMO.SQLServerClass();
            try
{
                svr.Connect(strServerName, strUserName, strPwd);
                foreach(SQLDMO.Database db in svr.Databases)
{
                    if(db.Name!=null)
                        alDbs.Add(db.Name);
                }
                this.cmbDb.DataSource = alDbs;
                bolReturn = true;
            }
            catch(Exception e)
{
                throw(new Exception("连接数据库出错："+e.Message));
            } 
            finally 
{
                svr.DisConnect();
                sqlApp.Quit();
            }
            return bolReturn;
        } 







                //数据库备份
        private void DbBackUp(string savepath, string database)
{
            SQLDMO.SQLServer svr = new SQLDMO.SQLServerClass();
            try
{
                svr.Connect(this.server, this.userid, this.password);
                SQLDMO.Backup bak = new SQLDMO.BackupClass();

                SQLDMO.BackupSink_PercentCompleteEventHandler pceh = new SQLDMO.BackupSink_PercentCompleteEventHandler(SetBarVisible);
                bak.PercentComplete += pceh;

                bak.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Database;

                bak.Initialize = true;
                bak.Files = savepath + @"\1.bak";
                bak.Database = database;
                bak.SQLBackup(svr);
            }
            catch(System.Exception xx)
{
                throw(new Exception("备份数据库失败" + xx.Message));
            }
            finally
{
                svr.DisConnect();
            }
