char (C# Reference)
Visual Studio 2008
The char keyword is used to declare a Unicode character in the range indicated in the following table. Unicode characters are 16-bit characters that are 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 |
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. In the following example four char variables are initialized with the same character X:
char[] chars = new char[4]; chars[0] = 'X'; // Character literal chars[1] = '\x0058'; // Hexadecimal chars[2] = (char)88; // Cast from integral type chars[3] = '\u0058'; // Unicode foreach (char c in chars) { Console.Write(c + " "); } // Output: X X X X
