C# data structure to handle a file
<p>I have a file which has data in the following format</p>

<pre><code>A   B
-----
40  3
50  2
60  1
</code></pre>

<p>I have to read the file and store it in a data structure that should help me manipulating the data.</p>

<p>If it is C I would go with linked list. What should I possibly use for C#?</p>
