easy and fast way to convert an int to binary?
<p>What I am looking for is something like PHPs <code>decbin</code> function in C#. That function converts decimals to its representation as a string.</p>

<p>For example, when using <code>decbin(21)</code> it returns <code>10101</code> as result.</p>

<p>I found <a href="http://www.globalguideline.com/articles/analysis.php?k=Converting%5FBetween%5FBinary%5Fand%5FDecimal%5Fin%5FC%5Fsharp">this function</a> which basically does what I want, but maybe there is a better / faster way?</p>
