Stripping out non-numeric characters in string in C#
There are many ways to strip out non-numeric characters in string, below is an example, we created a function calledGetNumbers() which takes input of string then we use Where() method and loop through characters and return only char.IsDigit(), the result will be collected to an array and then casted into a string.using System;
using System.Linq;
public class Program
{
private static string GetNumbers(string input)
{
return new string(input.Where(c => char.IsDigit(c)).ToArray());
}
public static void Main()
{
Console.WriteLine(GetNumbers("11a22b33c44d"));
}
}
