How to correctly represent a whitespace character

Question

I wanted to know how to represent a whitespace character in C#. I found the empty string representation string.Empty. Is there anything like that that represent

Answer 1

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));

Answer 2

Using regular expressions, you can represent any whitespace character with the metacharacter "\s"

Answer 3

You can always use Unicode character, for me personally this is the most clear solution:

var space = "\u0020"

Answer 4

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.

Answer 5

Which whitespace character? The most common is the normal space, which is between each word in my sentences. This is just " ".

Answer 6

No, there isn't such constant.
