title: How can I join int[] to a character-separated string in .NET?
body: <p>I have an array of integers:</p>
  <pre><code>int[] number = new int[] { 2,3,6,7 };
  </code></pre>
  <p>What is the easiest way of converting these into a single string where the numbers are separated by a character (like: <code>&quot;2,3,6,7&quot;</code>)?</p>
  <p>I'm using C# and .NET 3.5.</p>
