You will also notice both example using the <a href="http://msdn.microsoft.com/en-us/library/yh598w02.aspx" rel="nofollow noreferrer"><code>using</code></a> keyword. There's an explanation of why you want to use that construct in this question (and probably many others): <a href="https://stackoverflow.com/questions/567138/when-should-i-use-using-blocks-in-c">When should I use “using” blocks in C#?</a> It looks like you already fond the <a href="http://msdn.microsoft.com/en-us/library/3saad2h5.aspx" rel="nofollow noreferrer"><code>File</code></a> class, you could take advantage of the other methods in it that are specifically designed for working with text files.

That way you can get helpful tips about how to write better code.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
