title: Replace\remove character in string
body: <pre><code>string DelStr = "I! am! bored!";
  string RepStr = "10/07/10"
  </code></pre>
  
  <p>I want to delete all '!' on DelStr and I want to replace all '/' with '-' on the RepStr string.</p>
  
  <p>Is there any way to do this without doing a loop to go through each character? </p>
