Encoding « Encoding « Essential Types

The abstract class Encoding and its concrete subclasses provide a variety of encoding schemes.

Encoding name	Static property on Encoding
UTF-8	Encoding.UTF8
UTF-16	Encoding.Unicode
UTF-32	Encoding.UTF32
ASCII	Encoding.ASCII

Encoding Scheme	Class	Create Using
ASCII	ASCIIEncoding	GetEncoding ASCII property
Default	Encoding	GetEncoding Default property
UTF-7	UTF7Encoding	GetEncoding UTF7 property
UTF-8	UTF8Encoding	GetEncoding UTF8 property
UTF-16 (big-endian)	UnicodeEncoding	GetEncoding BigEndianUnicode property
UTF-16 (little-endian)	UnicodeEncoding	GetEncoding Unicode property
Windows OS	Encoding	GetEncoding(1252)
