Tutorial :How to get a Char from an ASCII Character Code in c#


Im trying to parse a file in c# that has field (string) arrays separated by ascii character codes 0, 1 and 2 (in Visual Basic 6 you can generate these by using Chr(0) or Chr(1) etc.)

I know that for character code 0 in c# you can do the following:

char separator = '\0';  

But this doesnt work for character codes 1 and 2?


Two options:

char c1 = '\u0001';  char c1 = (char) 1;  


You can simply write:

char c = (char) 2;  


char c = Convert.ToChar(2);  

or more complex option for ASCII encoding only

char[] characters = System.Text.Encoding.ASCII.GetChars(new byte[]{2});  char c = characters[0];  


It is important to notice that in C# the char type is stored as Unicode UTF-16.

From ASCII equivalent integer to char

char c = (char)88;


char c = Convert.ToChar(88)

From char to ASCII equivalent integer

int asciiCode = (int)'A';

The literal must be ASCII equivalent. For example:

string str = "Xสีน้ำเงิน"; Console.WriteLine((int)str[0]); Console.WriteLine((int)str[1]);

will print

X 3626

Extended ASCII ranges from 0 to 255.

From default UTF-16 literal to char

Using the Symbol

char c = 'X';

Using the Unicode code

char c = '\u0058';

Using the Hexadecimal

char c = '\x0058';
