Represents a substitute input string that is used when the original input character cannot be encoded. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
Initializes a new instance of the EncoderReplacementFallback object.class using the value of a
Determines whether the specified object is equal to the current object.(Inherited from Object.)
|Fallback(Char, Char, Int32)|
Indicates whether a replacement string can be used when an input surrogate pair cannot be encoded, or whether the surrogate pair can be ignored. Parameters specify the surrogate pair and the index position of the pair in the input.(Overrides EncoderFallbackBuffer::Fallback(Char, Char, Int32).)
Prepares the replacement fallback buffer to use the current replacement string.(Overrides EncoderFallbackBuffer::Fallback(Char, Int32).)
Serves as the default hash function. (Inherited from Object.)
Retrieves the next character in the replacement fallback buffer.(Overrides EncoderFallbackBuffer::GetNextChar().)
Initializes all internal state information and data in this instance of EncoderFallbackBuffer::Reset().).(Overrides
Returns a string that represents the current object.(Inherited from Object.)
It might not be possible to convert a character to an equivalent encoded byte sequence if no suitable encoding exists. A common reason for an encoding to fail is if the conversion operation uses a code page that cannot represent the character to encode.
If the input character cannot be converted to an output byte sequence, a System.Text::EncoderReplacementFallback object provides a replacement string that is substituted for the original input character. The replacement string initializes the value of the EncoderReplacementFallback object, and the value of the EncoderReplacementFallback object initializes the value of an object. The value of an object is called the replacement fallback buffer. The conversion operation encodes the replacement fallback buffer instead of the original input character, then continues to process the remainder of the input.
