Encoding

EncodingCF 1.0, ECMA 1.0, serializable

System.Text (mscorlib.dll)abstract class

This class converts strings of Unicode characters to and from byte arrays. Derived classes implement specific encoding types. The GetBytes( ) method takes an array of characters and returns the corresponding array of bytes. The GetChars( ) method does the opposite conversion. GetByteCount( ) and GetCharCount( ) allow you to get the exact size of the encoding or decoding to size the output buffer appropriately.

The GetEncoder( ) and GetDecoder( ) methods create Encoder and Decoder instances that allow you to do encoding across sequential blocks in which partial byte codes may remain in the buffer.
