title: how to read only numbers from text file in vb.net
body: <p>Hello people as the topic show I want to do in VB.net a script that gets only the numbers from a *.txt file</p>
  
  <p>EXAMPLE:</p>
  
  <p>text file:
  asd4lkj5fdl
  jklj235</p>
  
  <p>the result:
  45235</p>
  
  <p>I have done a research in Google and come up with nothing, I did saw a answer here but only in C
  I know that in theory it needs to be like this:
  Read every char loop ask if it is an integer add it to a new string if not continue to next char do this till the end of the stream</p>
  
  <p>Thanks for the one how helps !  </p>
