Extract multiple white spaces from a string

I want to get spaces that are longer than 1 space.

The following returns me the null characters between each letter, as well as spaces. However, I only want to highlight two lines of spaces between cand dand 3 lines of spaces between fand g.

string b = "ab c  def   gh";
List<string> c = Regex.Split(b, @"[^\s]").ToList();

UPDATE: The following works, but I'm looking for a more elegant way to achieve this:

c.RemoveAll(x => x == "" || x == " ");

. The desired result will be List<string>, containing " "and" "

If you want List<String>, as a result, you can execute this Linq query

string b = "ab c  def   gh";

List<String> c = Regex
  .Matches(b, @"\s{2,}")
  .OfType<Match>()
  .Select(match => match.Value)
  .ToList();

This will give you the desired list.

string b = "ab c  def   gh";
var regex = new Regex(@"\s\s+");
var result = new List<string>();
foreach (Match m in regex.Matches(b))
    result.Add(m.Value);
