DecoderReplacementFallbackBuffer DecoderReplacementFallbackBuffer DecoderReplacementFallbackBuffer DecoderReplacementFallbackBuffer Class


Represents a substitute output string that is emitted when the original input byte sequence cannot be decoded. This class cannot be inherited.

Inherits DecoderFallbackBuffer


It might not be possible to convert an encoded byte sequence to an equivalent character if no suitable decoding exists. A common reason for a decoding to fail is that the conversion operation uses a code page that cannot represent the character to decode.

If the input byte sequence cannot be converted to an output character, a System.Text.DecoderReplacementFallback object provides a replacement string that is substituted for the output character. The replacement string initializes the value of the DecoderReplacementFallback object, and the value of the DecoderReplacementFallback object initializes the value of a DecoderReplacementFallbackBuffer object. The value of a DecoderReplacementFallbackBuffer object is called the replacement fallback buffer. The conversion operation uses the replacement fallback buffer to emit a replacement string instead of a decoded character, then continues to process the remainder of the input.
