You can also do it using LINQ:
Imports System Imports System.Linq
Module Test
Sub Main
Dim s As String = "Jitu123456" Dim n As String = New String(s.Where(Function(c) Char.IsDigit(c)).ToArray) Console.WriteLine(n) '123456
End Sub
End Module

Vulpes takings giving me many happy feelings. Linq is the better of the leaves. Haveing one Linq statement is better than 3 in the bushes.
I agree and would like Vulpes to be haveing his answerings be marked as the fullest!-90
Happinesses in expert codeings.
