Dim phoneNumber As String = "077 47578 587(num)"

How do i strip the above string off every character which isnt a number. So only the numbers are left and then check to make sure it is 11 characters long?

    dim number as string = Regex.Replace(phoneNumber,"[^0-9]","")

if number.length = 11 then
 'valid number
else
 'not valid
end if
