which is collection or list is fastest for too many additions & deletions?
<p>I have a list in which large number of elements are added &amp; deleted <strong>every second</strong><br>
also i need to find elements in the list at the same time .</p>

<p>Also i need key/value pair comparison for searching.</p>

<p>Additions rate is higher than deletion . </p>

<p>Thanks In Advance. </p>
