DecoderReplacementFallbackBuffer Class
Represents a substitute output string that is emitted when the original input byte sequence cannot be decoded. This class cannot be inherited.
Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)
The DecoderReplacementFallbackBuffer type exposes the following members.
| Name | Description | |
|---|---|---|
 | DecoderReplacementFallbackBuffer | Initializes a new instance of the DecoderReplacementFallbackBuffer class using the value of a DecoderReplacementFallback object. |
| Name | Description | |
|---|---|---|
| Remaining | Gets the number of characters in the replacement fallback buffer that remain to be processed. (Overrides DecoderFallbackBuffer.Remaining.) |
| Name | Description | |
|---|---|---|
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Fallback | Prepares the replacement fallback buffer to use the current replacement string. (Overrides DecoderFallbackBuffer.Fallback(Byte[], Int32).) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetNextChar | Retrieves the next character in the replacement fallback buffer. (Overrides DecoderFallbackBuffer.GetNextChar().) |
| GetType | Gets the Type of the current instance. (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. (Overrides DecoderFallbackBuffer.MovePrevious().) |
| Reset | Initializes all internal state information and data in the DecoderReplacementFallbackBuffer object. (Overrides DecoderFallbackBuffer.Reset().) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
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.
