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

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.

The System..::.Char type provides several static methods for working with char values.
