    <p><strong><em>NOTE: <a href="https://stackoverflow.com/users/253576/ccalvert">Charlie Calvert</a> replied below that the 101 LINQ Samples have now been updated with correct code.</em></strong></p> <p>The MSDN Visual C# Developer Center has a section called <strong>101 LINQ Samples</strong>. I found this through a Bing search.</p> <p>The code for <a href="http://msdn.microsoft.com/en-us/vcsharp/aa336758#SelectManyCompoundfrom1" rel="nofollow noreferrer">SelectMany - Compound from 1</a> is:</p> <pre><code>public void Linq14() { int[] numbersA = { 0, 2, 4, 5, 6, 8, 9 }; int[] numbersB = { 1, 3, 5, 7, 8 }; var pairs = from a in numbersA, b in numbersB where a &lt; b select new {a, b}; Console.WriteLine("Pairs where a &lt; b:"); foreach (var pair in pairs) { Console.WriteLine("{0} is less than {1}", pair.a, pair.b); } } </code></pre> <p>However, <strong>this code won't compile</strong>. I noticed that if I remove the comma at the end of <code>from a in numbersA,</code> and instead add <code>from</code> in front of <code>b in numbersB</code>, it will compile and work fine:</p> <pre><code> var pairs = from a in numbersA from b in numbersB where a &lt; b select new {a, b}; </code></pre> <p>I'm not sure if this is a bug in MSDN's example or if possibly I'm running a version of C# and .NET that doesn't support this syntax.</p> <p>If I look at the breadcrumb at the top of the <strong>101 LINQ Samples</strong> website, I see it says "Future Versions". Does this indicate that future versions of C#/.NET will support using a comma instead of <code>from</code> in LINQ syntax?</p> <p><img src="https://i474.photobucket.com/albums/rr103/ossavir/LINQ_sample_breadcrumb.png"></p> <p>I'm using Visual Studio 2008 Standard with .NET 3.5 SP1.</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.
