#992 – The System.Char Data Type
December 10, 2013 Leave a comment
In C#, the char keyword is a synonym for the System.Char data type in the Base Class Library (BCL). An instance of a char represents a single character, i.e. a single unit that is part of a written language.
Some examples of characters, all of which can be represented by a char:
- Uppercase or lowercase alphabetic characters from the English (Latin) alphabet (a..z, A..Z)
- Accented alphabetic characters
- Alphabetic characters from other alphabets (e.g. Greek, Cyrillic, Hebrew, Chinese, Arabic, etc).
- Punctuation marks (e.g. ! , = [ {, etc).
- Numeric digits (0..9)
- Control or formatting characters (e.g. end-of-line, delete)
- Mathematical and musical symbols
- Special graphical glyphs (e.g. trademark symbol, smiley face)
A character stored in an instance of a char takes up 2 bytes (16 bits). The values are encoded as Unicode characters, using the UTF-16 encoding.
