how to get a particular value from NameValueCollection's comma-delimited string?
<p>i have a POST request</p>

<pre><code>firstname=1&amp;lastname=10&amp;firstname=2&amp;lastname=20&amp;firstname=3&amp;lastname=30.
</code></pre>

<p>then i get comma-delimited lists of names and values</p>

<pre><code>Request.Form["firstname"] // 1,2,3
Request.Form["lastname"] //10,20,30
</code></pre>

<p>it seems that NameValueCollection does not contain a method to access specified firstname value directly?</p>

<p>the task looks standard, like Request.Form index property in ASP.</p>

<p>of course i can implement a custom helper enumerator or simply parse strings someway, but i'm not sure there are no any standard solution.</p>

<p>to be honest, i would prefer to have direct access to each firstname-lastname pair, but i cannot ask impossible:).</p>
