remove , from string if present
<p>What is the best way to remove <code>,</code> from following strings.</p>

<ol>
<li>one,two,three,</li>
<li>three,four,five</li>
<li><p>six,seven,eight,nine,ten,</p>

<blockquote>
<pre><code>int strLength = someString.Length;

if (strLength &gt; 0)
{
     findString = findString .Substring(0, str.Length - 1);
}

if (findString ==",")
{
     someString.Remove(someString.Length - 1)
}
</code></pre>
</blockquote></li>
</ol>

<p>I have quickly compiled this code directly in StackExchange editor as an example (It may be have syntax error.</p>

<p>Please take above as logic purpose only.</p>

<p>I would appreciate if someone can provide optimized code for above logic.</p>

<p><strong>UPDATE</strong>: I actually want to remove  <code>,</code> from string if present at the end of string not in middle.</p>
