Retrieve and Remove elements from string
<p>Say I have a list of string </p>

<pre><code>List&lt;string&gt; lst=new List&lt;string&gt;(new string[]{"a","b","c","d"}); 
</code></pre>

<p>I wish to get element from index 0 to index 2 assign it to another List lst1(i.e. the element of lst  is <code>{"a","b"}</code>), then remove it from lst (i.e. lst becomes <code>{"c","d"}</code>， what's the quickest way of doing this? I am thinking is there any command like</p>

<pre><code>List&lt;string&gt; lst=new List&lt;string&gt;();
lst1=lst.getElements(1,2);
lst.remove(1,2);
</code></pre>
