What is correct way to a remove few characters at the end of string C#
<p>Consider the following code, what is the correct way to a remove the last two <code>&lt;br/&gt;</code> tags from the end of string in C#? I have followed very naive method, to achieve this. Can you please suggest improvements.</p>

<pre><code>List&lt;string&gt; MessageList; // populated from data source
Label lblHtmlOutput = new Label();
StringBuilder sb = new StringBuilder();
foreach (var item in MessageList)
{
    sb.Append(item + "&lt;br/&gt;&lt;br/&gt;");
}
sb.Remove(sb.Length - 11, sb.Length - 1);
</code></pre>
