Refrain from abusive code.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.

I would say it is not acceptable because your intent is not clear, which makes the code difficult to maintain.
The comment above the code in a must inherit class Authorization data members: If Clearance Is Required the user attempting to change the value will have their clearance level validated against the clearance required. Collects who and when this class was last updated by - for data merging such as offline files.

They are clearly separated by lines, if they were in the same line, then I would agree with you. As I said in my reply, it resembles a lot C++ declaration like:
private:
int x;
double y;

.The underscore even act as C++ semi-colon. It doesn't hurt readability as you can clearly see the types at the end of each line. I don't see any confusion, except that someone may be in doubt if the attribute applies only to the first variable or all of them.

If you have 35 or 40 of these grouped into one segment, they're going to flow off the screen. If you want to mark just one of them as "public", do you copy/paste this to some other part of the file entirely? How does this affect the attributes? Remember, after you copy/paste the private variable to the public section, the original attributes are on a completely different screen. And you're not instinctively moving the attribute along with the variable.

That's still confusion. And it's not really useful or purposeful confusion. You save a small number of characters and compile to the exact same IL code (hopefully) while introducing uncertainty for developers. This is the equivalent of doing C++ / C# if blocks without braces.

As a general rule, explicit intent is better coding practice than implied intent.
I rather have white space, but agreed.

This is actually one line of code, but that is why I break it into multiple lines using the _ character to cheat a little bit, so I only have to write the serialization tag once.

I write generics my classes are never more then 300 lines of code and if I need more then 4 or so data members I am doing something wrong Also I would never declare a member of a class public, I use properties to expose members. The only reason these are grouped together is so I do not have to write the serialization tag out for each, its cheating a bit.

This is what it looked like before
<System.Runtime.Serialization.DataMember>
Private mLastUpdated As DateTime<System.Runtime.Serialization.DataMember> Private mLastUpdatedBy As String <System.Runtime.Serialization.DataMember> Private mClearanceRequired As Int64 <System.Runtime.Serialization.DataMember> Private mClearanceIsRequired As BooleanThe first example I wrote, stands on in the document, where writing datamember so many times with the word private seems to be a waste of space.
So to clarify, you're saying that "saving space" is more important than "providing clarity" and "avoiding bugs"? If you're trying to save space why are you: 1. Using Private at all? That's the default, just take it out. 2. Using that little "m" in the prefix. Why not just lower-case the first letter? ("lastUpdated") 3. Using full words when you could abbreviate everything? ("lstUpd") 4. Not importing the System.Runtime.Serialization on the file? Then you could just type ""! If "saving space" is really important, why aren't you doing it everywhere? And at the end of the day, all of this code is functionally equivalent, right? So it all compiles to the same IL. I'm just not understanding the "save space" argument here.

The word Private indents the code for white space. The m stands for Member some companies use an underscore _ instead, each data member has a corresponding property that exposes the data member with extra code for validation, each of these properties implement an interface. The intent is white space and readability not saving space. Importing a class file is improper name resolution

Your own words literally say that you are worried about "wasting space". Now you've changed it slightly:
Quote:

You're worried about "wasting space" but only for some very specific and narrow scope of "wasting". And in this particular case, you're worried about "small waste" vs. "absolute clarity" which seems like a pretty lame trade-off. The fact that anyone had to question whether or not the attribute applied to all the variables means that you failed the "readability" test. Your goal of "readability" actually resulted in this code being hard to read and possibly being "unclear" to people who were not experts in this very narrow language feature.

White space. It's more important to people. Also as a programmer if you do not understand how a compiler is going to handle your code, you might consider another profession.
Yes, it's a matter of knowing how the compiler is going to handle the code, but it's more about maintainability. The format of the code is not to please the compiler. It's there to convey, without a doubt, what you intended. It's better to be explicitly expressive than it is to assume functionality with a lack of expression. Think about what the next guy who has to maintain your code is going to think when he sees it. Again, you're not looking for opinions. You're shooting down everything everyone says about what you wrote in an attempt to justify it.

If you're worried about space, why are you using one of the most verbose languages there is? :)

I see yes the context of how someone takes a sentence is important. The code is flawless, again the question was about coding practices.
When I commented on this branch of the thread, it wasn't addressed to you.

Dave KreskowiakWhite space and readability It's like taking actual English practices and applying them to coding, so the point reading code is like reading a paragraph - when it's so elegant writing comments are redundant.

yeah I like that way too. It's not about saving lines of code, it's about creating white space
