The char Type
A char holds exactly one letter, digit, or symbol, like a single tile in a word game. You write it with single quotes.
In this page:
Syntax
char variableName = 'A';
int code = (int)variableName;
bool isDigit = char.IsDigit(variableName);The char Type
A char represents a single UTF-16 character and is written with single quotes, like A. Characters can be compared, cast to their underlying numeric code point, and combined into strings. Double quotes are reserved for string, not char.
Note:
Casting a
char to int gives you its Unicode code point.Example: The char Type
using System;
class Program
{
static void Main(string[] args)
{
char letter = 'A';
char digit = '7';
Console.WriteLine(letter);
Console.WriteLine((int)letter);
Console.WriteLine(char.IsDigit(digit));
}
