    <p>To add to the other answers, if you don't want to parse the text file yourself, you could always use a quick and dirty regular expression if you're comfortable with them:</p> <pre><code>var regex = new Regex(@"Start Section \d+ - (?&lt;section&gt;\w+)\r\n(?&lt;list&gt;[\w\s]+)End Section", RegexOptions.IgnoreCase); var data = new Dictionary&lt;string, List&lt;string&gt;&gt;(); foreach (Match match in regex.Matches(File.ReadAllText("types.txt"))) { string section = match.Groups["section"].Value; string[] items = match.Groups["list"].Value.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries); data.Add(section, new List&lt;string&gt;(items)); } // data["animals"] now contains a list of "dog", "cat", "horse", and "cow" </code></pre> <p>In response to the comment:</p> <blockquote> <p>but "list" sounds so simple and basic (like i am going shopping), array has much nicer ring to it ;) But I will look in to them maybe a bit more, I got the impression from my research that arrays are more efficent code?</p> </blockquote> <p>It's not about whether a list vs. array is "basic" or "has a nicer ring", it's about the purpose of the code. In your case, you're iterating a file line-by-line and adding items to a collection of an unknown size beforehand - which is one problem a list was designed to solve. Of course you could peek through the file and determine the exact size, but is doing that worth the extra "efficiency" you get from using an array, and is iterating the file twice going to take longer than using a list in the first place? You don't know unless you profile your code and conclude that specific portion is a bottleneck... which I'll say, will almost never be the case.</p>

    2. CODam Internetfroze, OK sorry I think you miseed the sarcasam in my tone. I actuly started by using a fixed lenth array (had not ome across list), then found out about list so gave that a go, and then was playing about converting lists to arrays. At the moemnt this is all playing around seeing what things you can do these days. the finaly disecisions on what I will use will vary depending on what I am going to sue the arrays/lists for. I have a feeling it might end up a mixture. Still need to read up and find out lots more :)

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.
