C# method for encoding numbers such as 12 to obfuscated strings such as JH21EW3C or whatever
<p>Instead of having parameters such as  i want to have . </p>

<p>This is because I don't want to offer a simple way to see all content just by replacing 12 with 13, 14, 15 etc.</p>

<p>So I need a method which can encode a number into a string, and than decode.</p>

<p>something like</p>

<pre><code>httP://mysite.com?image=+encode(myNumber);when I create the link and 
</code></pre>

<p>decode(imageParam); when I get the value from the HTTp request.</p>

<p>Is there any method available which already does this?</p>
