Parameters chars A String to encode as a UTF8Encoding.Ī Int32 that specifies the number of bytes necessary to encode chars as a UTF8Encoding.Įrror-checking is turned on for the current instance and chars contains an invalid surrogate sequence. UTF8Encoding.GetByteCount(System.String) Method public override int GetByteCount(string chars) ĭetermines the number of bytes required to encode the If value is a UTF8Encoding and represents the same type and value as the Parameters value A Object to compare with the current instance. UTF8Encoding.Equals Method public override bool Equals(object value) ĭetermines whether the current instance and the UTF8Encoding() Constructor public UTF8Encoding() See Also 8Encoding Class, System.Text Namespace This constructor is equivalent to UTF8Encoding Parameters encoderShouldEmitUTF8Identifier A Boolean that indicates whether the Unicode byte order mark in UTF-8 is recognized or emitted when reading from or writing to a Stream.

Turned on when an instance of the class is constructed.
This class offers an error-checking feature that can be The byte order mark is used to distinguish UTF-8 text from The UTF-8 identifier is the Unicode byte order mark (0xFEFF) written in UTF-8 Yielding an efficient mechanism to encode English in an internationalizable way. This encoding is optimized for the lower 127 ASCII characters, [ Note: UTF-8 encodes Unicode characters with a variable number of bytes perĬharacter. Using the UTF-8 encoding (UCS Transformation Format, 8-bit form). 8Encoding Class 8Encoding Class public class UTF8Encoding : Encoding
