The Char value type represents Unicode characters with values ranging from hexadecimal 0x0000 to 0xFFFF.

Char provides methods to compare instances of this type, convert the value of an instance to its String representation, convert the String representation of a number to an instance of this type, and determine whether an instance is in a category such as digit, letter, punctuation, control character, and so on.

For information about how format specification codes control the String representation of value types, see Formatting Base Types.

For more information about Unicode, see the Unicode Standard at http://www.unicode.org.

This type implements interfaces IComparable and IConvertible. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.
