The char keyword is used to declare a Unicode character in the range indicated in the following table. Unicode characters are 16-bit characters used to represent most of the known written languages throughout the world.
|Type||Range||Size||.NET Framework type|
|char||U+0000 to U+ffff||Unicode 16-bit character||System.Char|
Constants of the char type can be written as character literals, hexadecimal escape sequence, or Unicode representation. You can also cast the integral character codes. All of the following statements declare a char variable and initialize it with the character
char MyChar = 'X'; // Character literal char MyChar = '\x0058'; // Hexadecimal char MyChar = (char)88; // Cast from integral type char MyChar = '\u0058'; // Unicode
A char can be implicitly converted to ushort, int, uint, long, ulong, float, double, or decimal. However, there are no implicit conversions from other types to the char type.
