struct

This simple value type represents a 16-bit Unicode character (from hexadecimal 0x0000 to 0xFFFF). You can convert a character to upper- or lowercase and get its numeric representation using the methods of a Char object. You can also test if it is a number, letter, or symbol by using the methods prefixed with Is . For exact information, use the GetUnicodeCategory( ) method to get an enumerated value from System.Globalization.UnicodeCategory . This classifies the character into one of about thirty categories.

This type is aliased as char in C#. If you need an array of chars, use the String class.
