Oracle允许数据库管理员使用SYSDBA或SYSOPER特权连接到Oracle数据库.这是通过ConnectionString的DBA Privilege属性完成的.

Oracle allows database administrators to connect to an Oracle Database with either SYSDBA or SYSOPER privileges. This is done through the DBA Privilege attribute of the ConnectionString.

//Connect SYS/SYS as SYSDBA   
con.ConnectionString = "User Id=SYS;Password=SYS;" + 
  "DBA Privilege=SYSDBA;Data Source=oracle;";
