DecoderExceptionFallbackBuffer DecoderExceptionFallbackBuffer DecoderExceptionFallbackBuffer DecoderExceptionFallbackBuffer Class

Definition

Throws DecoderFallbackException when an encoded input byte sequence cannot be converted to a decoded output character. This class cannot be inherited.

Remarks

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 byte sequence cannot be converted to an output character, the decoding operation calls the Fallback method, which throws DecoderFallbackException.

The System.Text.DecoderFallbackBuffer class, which represents a data buffer used in a decoding operation, is the base class for the DecoderExceptionFallbackBuffer class. However, instead of a data buffer, the DecoderExceptionFallbackBuffer class represents a standard behavior in which an exception is thrown if a decoding operation fails. No actual data buffer exists, and the members designed to manipulate such a buffer do no significant work.

Creates a shallow copy of the current Object.

(Inherited from Object)
MovePrevious() MovePrevious() MovePrevious() MovePrevious()

Causes the next call to GetNextChar() to access the exception data buffer character position that is prior to the current position.
