char

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

Literals

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 X:

char MyChar = 'X';        // Character literal
char MyChar = '\x0058';   // Hexadecimal
char MyChar = (char)88;   // Cast from integral type
char MyChar = '\u0058';   // Unicode

Conversions

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.
