    <p>In a C# application I am working on I have a very long identifier as follows:-</p> <pre><code>foo.bar.bwah.blah.whatever.very.very.huge </code></pre> <p>Whenever I to reference this object it's an absolute nightmare, and unfortunately I do need to reference it a lot:-</p> <pre><code>var something = foo.bar.bwah.blah.whatever.very.very.huge.a; var somethingElse = foo.bar.bwah.blah.whatever.very.very.huge.b; foo.bar.bwah.blah.whatever.very.very.huge.c = 12; </code></pre> <p>etc. etc.</p> <p>I want to update this code using a far smaller alias of some kind, the problem is however that I want to change the underlying reference, and have the alias update also <em>without explicitly updating the alias</em>.</p> <p>Currently if I do the following:-</p> <pre><code>foo.bar.bwah.blah.whatever.very.very.huge.a = "hello"; string shorter = foo.bar.bwah.blah.whatever.very.very.huge.a; foo.bar.bwah.blah.whatever.very.very.huge.a = "world"; Console.WriteLine(shorter); </code></pre> <p>It will output "hello". What I want to achieve is something like the following:-</p> <pre><code>foo.bar.bwah.blah.whatever.very.very.huge.a = "hello"; string** shorterPointer = &amp;foo.bar.bwah.blah.whatever.very.very.huge.a; foo.bar.bwah.blah.whatever.very.very.huge.a = "world"; Console.WriteLine(**shorter); </code></pre> <p>Which would output "world" as required.</p> <p>I believe you can achieve something like this using unsafe code in C#, however I <em>cannot</em> do that, I have to use safe code only.</p> <p>Does anybody have any ideas how I might achieve this?</p> <p><strong>Please Note:</strong> This question is not about strings being immutable, I know they are - in fact I assumed they are for the purposes of the question. It might perhaps be simpler if I used some other type... so when I assign "hello" to a then "world" to a, I am <em>instantiating different objects</em> on each occasion, hence my stored reference to a becomes invalid after re-assignment.</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.
