How to take specific set of characters out of overall string and save to array or list?

I have a string with Unicodes inside of it, and I am trying to extract each unicode from the overall string and save it to a list/array..

This is the overall string:

"test 🔷 test 💙 test 🔹"

I want the following list:

1. 🔷 2. 💙 3. 🔹

Right now I am trying the following:

string[] emojiSeparators = new string[] { "&#", ";" };
string[] resultEmojis;

resultEmojis = noHtmlEmoji.Split(
  emojiSeparators, StringSplitOptions.RemoveEmptyEntries);

But I am getting the words "test" added to the list like below:

I only want the unicodes saved to my list, so that I can iterate over them and do things.

>Solution :

I suggest matching with a help of regular expression:

using System.Linq;
using System.Text.RegularExpressions;

...

string[] resultEmojis = Regex
  .Matches(noHtmlEmoji, @"&#[1-9][0-9]{5}(?=;)")
  .Cast<Match>()
  .Select(match => match.Value)
  .ToArray();

Pattern &#[1-9][0-9]{5}(?=;) explained:

&#       - &# characters
[1-9]    - digit in 1..9 range
[0-9]{5} - 5 digits in 0..9 range
(?=;)    - ; character which is not included into the match
