    <p>I have what amounts to a multi-dimensional array.</p> <pre><code>int[][][] MyValues; </code></pre> <p>What I want is to access the indexes via a strongly typed equivelent, such as an enumeration. I'm aware that you can get the enumeration values from the Enum type, but it's a bit long winded for my tastes.</p> <p>I'd rather have a way to Strongly type the indexes.</p> <p>For example:</p> <pre><code>int CarNumber = MyValues[Racetrack.Daytona][Race.Daytona500][Driver.JGordon]; </code></pre> <p>This would, by virtue of it being enum-like, prevent any out of bounds exceptions from being thrown, plus it gives all the indexes a nice human readable meaning.</p> <p>I've implemented this using a dictionary approach, but it seems kind of heavy handed:</p> <pre><code>Dictionary&lt;Racetrack,Dictionary&lt;Race,&lt;Dictionary&lt;Driver,int&gt;&gt;&gt; = new Dictionary&lt;Racetrack,Dictionary&lt;Race,&lt;Dictionary&lt;Driver,int&gt;&gt;&gt;(); </code></pre> <p>which I can then access via enums, but I don't really like this approach. It seems "ugly".</p> <p><strong>I'm looking for some alternate methods to represent what is essentially a multi-dimensional array while using human readable indexers, while maintaining type safety (can't accidently use a Driver for a Race, for instance, so simply using consts is not a good approach).</strong></p> <p>Any suggestions?</p> <p>This will be a compile time array (example above is not real, just an illustration) so I don't have to worry about inserts or deletes or other manipulations of the array. It will stay immutable, both in values, size and layout.</p> <p>Using a static class with const values is not a good approach either, since it doesn't enforce that only the set of values defined can be passed as indexers.</p>

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.
