    <p>With the addition of the <a href="http://msdn.microsoft.com/en-us/library/system.tuple.aspx" rel="noreferrer">Tuple</a> class in .net 4, I have been trying to decide if using them in my design is a bad choice or not. The way I see it, a <a href="http://msdn.microsoft.com/en-us/library/system.tuple.aspx" rel="noreferrer">Tuple</a> can be a shortcut to writing a result class (I am sure there are other uses too). </p> <p>So this:</p> <pre><code>public class ResultType { public string StringValue { get; set; } public int IntValue { get; set; } } public ResultType GetAClassedValue() { //..Do Some Stuff ResultType result = new ResultType { StringValue = "A String", IntValue = 2 }; return result; } </code></pre> <p>Is equivalent to this:</p> <pre><code>public Tuple&lt;string, int&gt; GetATupledValue() { //...Do Some stuff Tuple&lt;string, int&gt; result = new Tuple&lt;string, int&gt;("A String", 2); return result; } </code></pre> <p>So setting aside the possibility that I am missing the point of Tuples, is the example with a <a href="http://msdn.microsoft.com/en-us/library/system.tuple.aspx" rel="noreferrer">Tuple</a> a bad design choice? To me it seems like less clutter, but not as self documenting and clean. Meaning that with the type <code>ResultType</code>, it is very clear later on what each part of the class means but you have extra code to maintain. With the <code>Tuple&lt;string, int&gt;</code> you will need to look up and figure out what each <code>Item</code> represents, but you write and maintain less code.</p> <p>Any experience you have had with this choice would be greatly appreciated.</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.
