System.Text Namespace

The System.Text namespace contains classes representing ASCII, Unicode, UTF-7, and UTF-8 character encodings; abstract base classes for converting blocks of characters to and from blocks of bytes; and a helper class that manipulates and formats String objects without creating intermediate instances of String.

Classes

---

	Class	Description
	ASCIIEncoding	Represents an ASCII character encoding of Unicode characters.
	Decoder	Converts a sequence of encoded bytes into a set of characters.
	DecoderExceptionFallback	Throws DecoderFallbackException if an encoded input byte sequence cannot be converted to a decoded output character. This class cannot be inherited.
	DecoderExceptionFallbackBuffer	Throws DecoderFallbackException when an encoded input byte sequence cannot be converted to a decoded output character. This class cannot be inherited.
	DecoderFallback	Provides a failure-handling mechanism, called a fallback, for an encoded input byte sequence that cannot be converted to an output character.
	DecoderFallbackBuffer	Passes a string to a decoding operation that is emitted instead of an output character because an input byte sequence cannot be decoded.
	DecoderFallbackException	The exception that is thrown when a decoder fallback operation fails. This class cannot be inherited.
	DecoderReplacementFallback	Provides a failure-handling mechanism, called a fallback, for an encoded input byte sequence that cannot be converted to an output character. The fallback emits a user-specified replacement string instead of a decoded input byte sequence. This class cannot be inherited.
	DecoderReplacementFallbackBuffer	Represents a substitute output string that is emitted when the original input byte sequence cannot be decoded. This class cannot be inherited.
	Encoder	Converts a set of characters into a sequence of bytes.
	EncoderExceptionFallback	Throws an EncoderFallbackException if an input character cannot be converted to an encoded output byte sequence. This class cannot be inherited.
	EncoderExceptionFallbackBuffer	Throws EncoderFallbackException when an input character cannot be converted to an encoded output byte sequence. This class cannot be inherited.
	EncoderFallback	Provides a failure-handling mechanism, called a fallback, for an input character that cannot be converted to an encoded output byte sequence.
	EncoderFallbackBuffer	Passes a substitute string to an encoding operation. The string is used in place of any input character that cannot be encoded.
	EncoderFallbackException	The exception that is thrown when an encoder fallback operation fails. This class cannot be inherited.
	EncoderReplacementFallback	Provides a failure handling mechanism, called a fallback, for an input character that cannot be converted to an output byte sequence. The fallback provides a user-specified replacement string in place of the original input character. This class cannot be inherited.
	EncoderReplacementFallbackBuffer	Represents a substitute input string that is used when the original input character cannot be encoded. This class cannot be inherited.
	Encoding	Represents a character encoding.
	EncodingInfo	Provides basic information about an encoding.
	MLangCodePageEncoding
	StringBuilder	Represents a mutable string of characters. This class cannot be inherited.
	UnicodeEncoding	Represents a UTF-16 encoding of Unicode characters.
	UTF32Encoding	Represents a UTF-32 encoding of Unicode characters.
	UTF7Encoding	Represents a UTF-7 encoding of Unicode characters.
	UTF8Encoding	Represents a UTF-8 encoding of Unicode characters.
