char (C # Reference)

• 2019/10/22

char Type the keyword is the .NET  System.Char  structure type alias that represents the Unicode UTF-16 characters :

Types of	range	size	.NET type
char	U+0000 到 U+FFFF	# 16	System.Char

text

char Types of constants can be written as a character text, hexadecimal escape sequences or Unicode representation . Integer character codes may be converted to the corresponding force  char values. In the following example, the same character  X of the  char four elements of the array are initialized:

C#copy

Var 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

Console.Write(string.Join(" ", chars));
// Output: X X X X

Change

char Types implicitly converted to the integerushort type: int, uint, , long and  ulong. It may be implicitly built converted to floating point numeric types: float, double and  decimal. It can be explicitly converted to  sbyte, byte and  short integral type.

Other types can not be implicitly converted to  char type. However, any integer or floating point numeric type can be explicitly converted  char.
