Thousand separated value to integer
<p>I want to convert a thousand separated value to integer but am getting one exception.</p>

<pre><code>double d = Convert.ToDouble("100,100,100"); 
</code></pre>

<p>is working fine and getting <code>d=100100100</code></p>

<pre><code>int n = Convert.ToInt32("100,100,100");
</code></pre>

<p>is getting one format exception</p>

<blockquote>
  <p>Input string was not in a correct format</p>
</blockquote>

<p>Why?</p>
