Aaaarg....use the namespace

This isn't like a hidden bug or the things we usually see over here... I think CP has some people that maybe like that style...

I disagree, it's just code, the compiler doesn't care* and it's better to give the next developer too much information rather than too little. But could they have all shared one static instance? How often are these methods called? Are there threading issues? How big do the StringBuilders become? Can you estimate how big? If large, then pre-allocating enough memory or re-using existing instances can eliminate a lot of needless re-allocation. * However, I suspect that when you use the using directive** the compiler must have to spend some additional time looking them up. ** Qualification added for clarification.
Actually, it's less time. As the compiler already knows in what namespace the StringBuilder is, he doesn't need to search all the used namespaces... But this difference is imperceptible.

That's not "style", but a "preference"; the difference is that one needs arguments, the other doesn't. People who prefer the long naming should try prefixing everything with "global::".

Personally, I always import, unless there is already something with the same name imported. But it's a matter of taste.

But that's not what the
usingdirective does. There is no "import" in C# -- the closest to that is references. -
Just a little reminder: This is the "Hall Of Shame" and not he "Hall Of Bugs". There is no good reason to clutter ones code with superflous repetitions of the namespace prefixing the StringBuilder, except maybe when there is another implementation of StringBuilder floating around. Just my two cents! :)

You specified it when you wrote
System.Text.StringBuilder...I'm brazilian and english (well, human languages in general) aren't my best skill, so, sorry by my english. (if you want we can speak in C# or VB.Net =p)
Ah, so perhaps you were agreeing with me. I see now that my statement was unclear and I have added clarification.

Yes yes, I really have bad time expressing this things on languages other than my own... (actually, even in my own language sometimes I've bad times trying to express my self... :( )

..a good idea, if you are paid per line written. It should feel comparably to explicitly stating that a member is "private", and prefixing everything possible with "this".

Which everyone should do. There should be no default access modifiers.

Which I also do. Just because. :cool:

The amount of symbols that you use to convey an idea would best be kept to a minimum.

No, you prefix the member if a class with
thisto prevent any ambiguity. The method or property on it's own only implies where it is. If I have this code:class Thingy {
private int majig = 27;void summit() { if (majig > 42) { // clever code } }}
And I copy the test to another method, all bad things could happen:
void nuThang() { // lots of code int majig = 69; // lots more code // copied: if (majig > 42) { // clever code } }oops.

Copy/paste is often an invitation not to check what you just pasted. Your example might be a nice example on why we introduced the DRY principle, but being this abstract, one can't be sure. But no, I'd not be bloating my code for the sake of "easy copies". If it's that re-usable, I'll take the time to make it a snippet. --edit;

Do you have global variables that clash with the names of the property/method that you're calling from the current object that you need to specify explicitly that you need the property/method from "this" object?

I don't see the shame on this, this guy just like to write long names :|

:doh: Huh? I don't, read my message again. I don't want the repetitions so I just mentioned the namespace at the top & replaced things.

There I mentioned
StringBuilderis just an example. I found many similar things like below.System.Diagnostics.Trace.Write
System.Diagnostics.Trace.WriteLine
System.Drawing.Color
System.Configuration.Configuration
System.IO.StreamWriter
System.IO.StreamReader
System.IO.FileInfo
System.IO.FileStream
System.IO.StringReader
System.IO.StringWriter
System.IO.TextReader
System.IO.TextWriter
System.Xml.XmlDocument
etc.,
....
...
..
.Why so much repetitions? After that some more 100s of replacements done. Namespace at top.
