c# count integers in string

[bubbisthedog]

I'm looking for the most efficient way to count the number of 0-9 integers in a string. I could write it, but it may be much less efficient than some of you peeps may know of. Any suggestions or solutions are welcomed.

Thanks,

For now I'm using

int Count;
string IntArray = "0123456789";
foreach (char Temp in CityString) {
if (IntArray.IndexOf(Temp) != -1) {
Count++;
}
}

Eh, it's a way to do it, but I'd love to see something more efficient if it exists...

You could do something like this:

Console.WriteLine(Regex.Replace("x1c2b3n4mdsd5h6k7h8k9h", "[^0-9]", "").Length.ToString());

Let me know how it works for you.

peace yo!
