Need a regular expression or similar to verify entered mobilenumbers in VB.NET!
Hello,
I need to write a regular expression or something similar that checks wether an entered mobile number is correct. Code is vb.net!
The numbers are all entered in one and the same textbox wich after clicking the submit button is verified by code and returns a boolean wether the number is correct or not.
The mobile number may also not contain letters and may not be empty and may not hold more than 17 characters including spaces.
Here are some examples of mobile numbers which are accepted and valid:
0031 6 12345678 (dutch mobile numbers)
0032 473 123456 (belgian mobile numbers)
0049 175 1234567 (German mobile numbers)
So basically for the dutch number that would be:
00<landcode><space><netnum ber without 0><space><number>
00<31> <6> <12345678>
belgian number :
00<landcode><space><netnum ber without 0><space><number>
00<32> <473> <123456>
german number :
00<landcode><space><netnum ber without 0><space><number>
00<49> <175> <1234567>
It doesnt have to be a regular expression but it would be great if it were. So long as the code works and does what it is supposed to do then thats alright with me.
Therefore I'm gonna give this question 400 points. Happy code solving fella's and dudettes.
Kind regards,
Gizeh

This should do what you need.
Imports System.Text.RegularExpress
' Sample Data
Dim input As String = "0032 473 123456"
If Regex.Match(input, "^00\d\d\s[1-9]\d*\s[1-9]\
MessageBox.Show("Cell number is valid")
Else
MessageBox.Show("Cell number is NOT valid")
End If
