Assembly: mscorlib (in mscorlib.dll)
A common reason for an encoding or decoding operation to fail is if the underlying encoding class does not provide a mapping between a character and an equivalent byte sequence. If the input character cannot be converted to an output byte sequence, the encoding operation calls the Fallback method, which throws EncoderFallbackException.
The System.Text.EncoderFallbackBuffer class, which represents a data buffer used in an encoding operation, is the base class for the EncoderExceptionFallbackBuffer class. However, instead of a data buffer, the EncoderExceptionFallbackBuffer object represents a standard behavior wherein an exception is thrown if an encoding operation fails. No actual data buffer exists, and the members designed to manipulate such a buffer do no significant work.
