0031 char escape sequence
<![CDATA[
Some characters are not typeable from keyboard directly. For example, the new line character.
In such circumstance we use escape sequence to represent the special character value.
An escape sequence starts with backslash.
Char Meaning Value
\' Single quote 0x0027
\" Double quote 0x0022
\\ Backslash 0x005C
\0 Null 0x0000
\a Alert 0x0007
\b Backspace 0x0008
\f Form feed 0x000C
\n New line 0x000A
\r Carriage return 0x000D
\t Horizontal tab 0x0009
\v Vertical tab 0x000B
The following example shows how to use the escape sequence.
using System;
class Program
{
static void Main(string[] args)
{
char newLine = '\n';
char singleQuote = '\'';
Console.WriteLine(newLine);
Console.WriteLine(singleQuote);
}
}
The output:

The following code shoes how to create unicode char literal:
