With this class, you can ensure that the current process has the
required security level to access the OLE DB .NET provider before you
attempt to open a connection. If it doesn't, a
System.Security.SecurityException will be thrown.
You can also use this class to programmatically revoke the permission
to access the OLE DB .NET provider for the current method call.
Note that this class pertains only to code access security (the
policy of allowed and disallowed actions you have configured using
the .NET Framework Configuration Tool or the
caspol.exe command-line utility). For more
information, refer to the reference for the base class
System.Data.Common.DBDataPermission . Currently,
there are only two additional restrictions you can impose: denying
the right to use blank passwords in a connection string and
restricting the allowed OLE DB drivers.
