How to remove identical items from List<string>?
<p>I have a List in which I select users from db each time a sql query runs with certain value and selects one user in the time thus I cannot limit identical users in sql.</p>

<p>I have list with:</p>

<pre><code>list[0] = "jerry"
list[1] = "tom"
list[2] = "jerry"
</code></pre>

<p>I want any (first or last doesn't matter in my case) to be removed from the list.</p>

<p>Thanks</p>
