title: How to convert Word or Number to list of Letters or Numbers?
body: <p>I'm new for C#, but have some basic question:</p>
  <p>I need to convert some words, for example: &quot;Hello&quot;(string) to list of letters&quot; &quot;H&quot;,&quot;e&quot;,&quot;l&quot;,&quot;l&quot;,&quot;o&quot;.
  Or Number 3242, to list or array of numbers: [3,2,4,2].</p>
  <p>How to do that?
  And how after that I can change any number or letter in lists?
  In Python its very easy. But in C# I don't know what to do.</p>
  <p>Please provide LOGICAL and EASY solution. I don't need some 50 lines script which using 20 functions. I'm interested in basic understanding of that process with easy solution, if it existing.</p>
  <p>Thank you guys,
  P.S: i'm using    .Net 3.1</p>
