Well I started programming in Java and we were told to put all our declarations up the top (which i think is the Java coding standard), and i like it this way. Makes all your declarations easy to find.
However, sometimes i need a variable at that scope which will only be used further down, so i put it there. It all comes down to the scope of you're variable and where it's used in that scope as to where it should go

Actualy it arose from some code i wrote in .Net.
I wrapped a generic HttpSession collection in something that exposed typed properties for each of the items it contained, And was told it was a total waste of my time.

Because the general concencus was that "It's the most pointless piece of code" they had ever seen.

I'd have to see the code.

<br />
public class SessionWrapper<br />
{<br />
<br />
private HttpSessionState session;<br />
<br />
<br />
public SessionWrapper()<br />
{<br />
session = HttpContext.Current.Session;<br />
}<br />
<br />
public string UserName<br />
{<br />
get{return (string)session[SE_USER_NAME];}<br />
set{session[SE_USER_NAME] = value;}<br />
}<br />
<br />
public int? LastPurchase<br />
{<br />
get{return (int?)session[SE_LAST_PURCHASE];}<br />
set{session[SE_LAST_PURCHASE] = value;}<br />
}<br />
<br />
<br />
}<br />
<br />
I'm actualy working on a code generator to build stuff like that for me, but at the time it was written manualy.
My argument was its a strongly typed wrapper that exposes other developers to exactly what they need, what type it is, and hides the constants.

Makes sense to me.
A similar thing I do is with ExecuteScalar() , which returns object which then (usually) requires a test for null and a cast, and setting a default value if null. I wrote a wrapper like public virtual T ExecuteScalar<T>(T IfNull){...} to handle the cast. Any time I'm writing a scalar query and don't have to test for null and/or do a cast I save time, the code is more readable too.
Usually, spending the time to encapsulate such common tasks will pay off.

Well i spent a few months crusading for sensible coding practices, and now i've given up. The other day i was told to remove it, re-centralise all the constants and simply use Session[AppConstants.CONST_NAME] to access everything.

I'm in a small IT department too, that was the CTO and Senior Developer pulling rank on my design decision. :S

I just spent the day (working from home) writing a wrapper for NumericUpDown that is generic and will take any of the built-in numerics, hide the actual decimal, and handle the casting so I don't have to.
Ugly as Hillary, but it works.

Maybe it was just the code.
Strong typing is a good way to control up front what type of information you are looking for rather than waiting for it to hit the database or a flat file and finding out later it isnt what it should be.

While converting an existing internal application from vb6 to c# i came accross the following :
'Reusable code -- Cut from here --
do some work here

So you can guess what happens when you change something in that code block

Ummm... no? I'm guessing either nothing or something catastrophic.

Yes if you don't copy&paste modifications of that so called "reusable" code to all places where it was "reused".

Ah! A Visual Studio Code snippet!

Ah, now that makes sense... kinda.

Some of those "snippets" were indeed pasted all over the place ... Imagine my surprise when the original author could not understand why his updates didnt work like it should

Maybe he should use the "C preprocessor" with his BASIC code.

Very nice resusable code
