title: Regex for alphanumeric, at least 1 number and special chars
body: <p>I am trying to find a regex which will give me the following validation:</p>
  
  <p>string should contain at least 1 digit and at least 1 special character. Does allow alphanumeric.</p>
  
  <p>I tried the following but this fails:</p>
  
  <pre><code>@"^[a-zA-Z0-9@#$%&amp;*+\-_(),+':;?.,!\[\]\s\\/]+$]"
  </code></pre>
  
  <p>I tried "password1$" but that failed
  I also tried "Password1!" but that also failed.</p>
  
  <p>ideas?</p>
  
  <p><strong>UPDATE</strong>
  Need the solution to work with C# - currently the suggestions posted as of Oct 22 2013 do not appear to work. </p>
