Encoding.GetEncoder( ) returns an
instance of this type, which
converts character arrays to byte arrays using the encoding subclass
from which it was constructed. This class exposes the
GetBytes( ) method, which converts a sequence of
character blocks into a sequence of byte blocks. Since
Encoder maintains state between calls to
GetBytes( ), it can deal with partial sequences
that occur at block boundaries.
The last argument to GetBytes( ) is a boolean that
specifies whether the internal buffer is flushed after the method is
called. If true, state information on the object
is lost between blocks. If false (the default),
the buffer is maintained. A call with flushing set to
true is needed on the final call to
Encoding.GetBytes( ) to close the byte array
properly.
