[SOLVED] Get first numbers from String

Issue

How to get the first numbers from a string?

Example: I have “1567438absdg345”

I only want to get “1567438” without “absdg345”, I want it to be dynamic, get the first occurrence of Alphabet index and remove everything after it.

Solution

You can use the TakeWhile extension methods to get characters from the string as long as they are digits:

string input = "1567438absdg345";

string digits = new String(input.TakeWhile(Char.IsDigit).ToArray());
