Is there an easy way to trim the last three characters off a string
<p>I have strings like this:</p>

<pre><code>var a = "abcdefg";
var b = "xxxxxxxx";
</code></pre>

<p>The strings are always longer than five characters. </p>

<p>Now I need to trim off the last 3 characters. Is there some simple way that I can do this with C#?</p>
