Match all digits but splitted in single characters

This is my string:

Hello world, '4567' is my number.

If /g (global modifier) was supported in .NET, There was no problem to get what I want, but now, I don't know what to do and need your help. I need match all digits (4567) but splitted in single characters. I want it like this:

match 1: 4, match 2: 5, match 3: 6, match 4: 7

Thanks, Alireza

I know the question has been tagged with Regex, but here is another option without REGEX

foreach (var item in "Hello world, '4567' is my number.".Where(char.IsDigit))
{
    Console.WriteLine(item);
}

Without , separation:

var matches = Regex.Matches("Hello world, '4567' is my number 679.", "\\d");
for (int i = 0; i < matches.Count; i++)
    Console.WriteLine(string.Format("Match {0}: {1}", i + 1, matches[i].ToString()));

It also works if you have more than once numbers in your string.

Output:

Match 1: 4

Match 2: 5

Match 3: 6

Match 4: 7

Match 5: 6

Match 6: 7

Match 7: 9

With , separation:

var matches = Regex.Matches(myString, "\\d");
string result = string.Empty;
for (int i = 0; i < matches.Count; i++)
    result += string.Format("Match {0}: {1}", i + 1, matches[i].ToString() + ", ");

Console.WriteLine(result.Trim().Trim(','));

Output:

Match 1: 4, Match 2: 5, Match 3: 6, Match 4: 7, Match 5: 6, Match 6: 7, Match 7: 9

You can use Regex.Matches to get all the matches i.e. digits in your case.

var matches = Regex.Matches("Hello world, '4567' is my number.", "\\d"); 
    foreach(Match match in matches)
       Console.WriteLine(match.Value);
