Question

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.

Answer 1

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());
