title: check string contained in a list of strings
body: <p>What is the best way to check if a string (of ints) is within a list of string?</p>
  
  <p>E.g. Check whether '1' is in (1,2,9,10,11,15)</p>
  
  <p>I had something like:</p>
  
  <pre><code>  if(listofString.Contains(radiolist.SelectedValue))
  </code></pre>
  
  <p>where the radiolist.SelectedValue is an integer stored in string form.</p>
  
  <p>I don't think the above would work because the '1' would probably match '11' in the string.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks!</p>
