Hi Jitendra,

Try this...

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

    Untitled Page














Imports System.Text.RegularExpressions
Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub btncollect_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btncollect.Click
        lblMessage.Text = CollectNumbers(txtInput.Text)
    End Sub

    Public Function CollectNumbers(ByVal collectnum As String) As String
        Return String.Join(Nothing, Regex.Split(collectnum, "[^\d]"))
    End Function
End Class

Thanks

Vulpes has been written:

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.
