I hope this helps you . Need a JavaScript regular expression for validating a string that should start with a forward slash ("/") followed by alphanumeric characters with no spaces? , The regex you need is:
code :
/^\/[a-z0-9]+$/i

it helps some times Since a Base64 string only contains ASCII characters, the string will occupy as many bytes and it has characters, i.e. s.length(), regardless of character set.
Unless you save the file in UTF-16 (double the size) or UTF-32 (quadruple the size) or some other multi-byte characters set, but that's rare.

will help you How can one perform this split with the Regex.Split(input, pattern) method? , I suggest matching, i.e. extracting words, not splitting:
code :
string source = @"This is a [normal string ] made up of # different types # of characters";

// Three possibilities:
//   - plain word [A-Za-z]+
//   - # ... # quotation
//   - [ ... ] quotation  
string pattern = @"[A-Za-z]+|(#.*?#)|(\[.*?\])";

var words = Regex
  .Matches(source, pattern)
  .OfType<Match>()
  .Select(match => match.Value)
  .ToArray();

Console.WriteLine(string.Join(Environment.NewLine, words
  .Select((w, i) => $"{i + 1}. {w}")));
1. This
2. is
3. a
4. [normal string ]
5. made
6. up
7. of
8. # different types #
9. of
10. characters
