How to correctly represent a whitespace character

So I had the same problem so what I did was create a string with a white space and just index the character.

String string = "Hello Morning Good Night";

char empty =  string.charAt(5);

Now whenever I need a empty character I will pull it from my reference in memory.

Which whitespace character? The empty string is pretty unambiguous - it's a sequence of 0 characters. However, " ", "\t" and "\n" are all strings containing a single character which is characterized as whitespace.

If you just mean a space, use a space. If you mean some other whitespace character, there may well be a custom escape sequence for it (e.g. "\t" for tab) or you can use a Unicode escape sequence ("\uxxxx"). I would discourage you from including non-ASCII characters in your source code, particularly whitespace ones.

EDIT: Now that you've explained what you want to do (which should have been in your question to start with) you'd be better off using Regex.Split with a regular expression of \s which represents whitespace:

Regex regex = new Regex(@"\s");
string[] bits = regex.Split(text.ToLower());

See the Regex Character Classes documentation for more information on other character classes.

No, there isn't such constant.

The WhiteSpace CHAR can be referenced using ASCII Codes here. And Character# 32 represents a white space, Therefore:

char space = (char)32;

For example, you can use this approach to produce desired number of white spaces anywhere you want:

int _length = {desired number of white spaces}
string.Empty.PadRight(_length, (char)32));
