Throws System.Text.DecoderFallbackException when an encoded input byte sequence cannot be converted to a decoded output character. This class cannot be inherited.
See Also: DecoderExceptionFallbackBuffer Members
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 DecoderExceptionFallbackBuffer.Fallback(Byte, int) method, which throws System.Text.DecoderFallbackException.
The System.Text.DecoderFallbackBuffer class, which represents a data buffer used in a decoding operation, is the base class for the System.Text.DecoderExceptionFallbackBuffer class. However, instead of a data buffer, the System.Text.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.
