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

Remarks
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.
Constructors
DecoderReplacementFallbackBuffer(DecoderReplacementFallback) |
Initializes a new instance of the DecoderReplacementFallbackBuffer class using the value of a DecoderReplacementFallback object. |
Properties
Remaining |
Gets the number of characters in the replacement fallback buffer that remain to be processed. |
Methods
Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
Fallback(Byte[], Int32) |
Prepares the replacement fallback buffer to use the current replacement string. |
GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
GetNextChar() |
Retrieves the next character in the replacement fallback buffer. |
GetType() |
Gets the Type of the current instance. (Inherited from Object) |
MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
MovePrevious() |
Causes the next call to GetNextChar() to access the character position in the replacement fallback buffer prior to the current character position. |
Reset() |
Initializes all internal state information and data in the DecoderReplacementFallbackBuffer object. |
ToString() |
Returns a string that represents the current object. (Inherited from Object) |
