You're on. You can't beat your chocolate hobnob. Well, not in a crowded campsite field anyway.

All are different functions but doing almost same work.So my choice better to use IsNullOrEmpty() as its safe and performance is good as compare to IsNullOrWhiteSpace().As IsNullOrWhiteSpace()can be removed if you are not using Unicode data.Apart from that other functions Equals and Length check functions having some performance issues in large projects.
So I prefer ISNullOrEmpty() in many situation.
At last its depend upopn the code what it needs.
Thanks.

You do know that IsNullOrEmpty IS NOT the same as IsNullOrWhitespace don't you? If I were to paste a tab into a field, for instance, and I'm expecting it to contain a proper value, IsNullOrEmpty will let that past whereas IsNullOrWhitespace will properly identify that there's a whitespace character in there.

Just picking up on one specific part of your question :
Coder For Hire wrote: But do you REALLY care about TICKS???
With today's PC's and Servers running at ultra high speed, why would anyone really care?
Ah, if only...
For some usage, maybe not, but there are many application areas where performance is very important.
Modern servers may be high performance, but if you're getting Google or Amazon rate hits, then your users might start to notice a slow-down.
Gamers are also very critical of poor performance, and will notice if your refresh rate is too slow or, worse, not consistent. Been there, done that, and sometimes you work hard to squeeze out the last ounce of performance from a system.
And there are a lot of systems out there running on lower-spec hardware, especially in the embedded world, and every cycle counts in those apps. Currently there and doing that - and again, you can't afford to waste any resources, processor, memory or I/O.
Of course, I would very much hope that in any time-critical or mission-critical application, string comparisons were kept to an absolute minimum, but I have occasionally seen some coding horrors and "stringly typed" (to borrow a friend's phrase) parameters...

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Perhaps if you try to describe this as if to your mother over the phone?

I'm guessing from that that I have offended you - if so, I apologize; that was not the intention. The intention was to let you know in simple, easy-to-translate-via-Google terms that we need fuller information, but that without seeing your screen or knowing anything about the context of your question it's best to try explaining as if to a non-technical person with whom you are familiar: hence your mother.
The end of your sentence however makes no sense to me at all: please stop using text abbreviations - you have a full keyboard, use it.
The rest of your message still doesn't help us to know what your code is like - and without that we can;t give you specific answers. Think of it as when your car breaks down: if you ring the garage ans say "it broke" and put the phone down they aren't going to rush to where you are and fix it because they don't know:
1) Who you are.
2) What make or model of car it is.
3) Where the car is.
4) What has broken.
5) What equipment or parts they need to bring.
We are in the same situation: all we know is that you have a C# service that sends you notices. How you receive them, where your app is, how you store them, etc., we do not know - because we can't see your screen, access your HDD, or read your mind! We have no idea of the context behind your question - we just get exactly what you type to work from.
So try again, and pretend you know nothing about your project - what do you need to tell yourself so you understand!

I know you know your project well - but we don't!
Let's turn it round for a moment: This is a modification ticket from one of my apps:
When adding a Video or Serial name, replace "’" with "'" - they are visually similar, but do not match for searching (Database integrity update required to fix existing examples). An "update application" has been created to do this correction in existing examples - ask for DBIntegrityUpdater.EXE
Now, I know what that means - because I know my project - but can you tell me exactly what I should do to implement it? And where?
Of course you can't - you have no idea even of how many layers are involved, much less which layer contains the relevant code because you have no context for the project and there are literally thousands of different ways it could have been implemented. We have the same difficulty with yours - we have no idea how your project works at the moment, so all we are asking for is the information we need!

It sounds like you need a separate method that you call beforehand to see if there are any outstanding items to pull down, then only issue your call to pull the full details down if this is empty. I'm not sure what you need help with here as this seems to be an extremely simple thing to do.

I'm not replying like I'm superior to you. I'm replying like this because I don't know exactly what you are stuck on. However, until you can explain exactly what the problem is that you are facing, then you aren't going to get much help, no matter which site you go to for answers. Try asking a question like this on StackOverflow and see how quickly they shut it down.
What you need to do is explain exactly what you are trying to achieve, and what problem you are having doing that. Is your problem at the web service side? Where does this list of notifications come from? How is your polling done? These are questions you are going to have to explain before anyone can help you.
The bottom line - if you can't explain what problems you are having, then no one is going to be able to help you and you're just going to end up getting frustrated. As OriginalGriff has said - we can't see your computer so we don't know what code you have or what architecture you are using. We don't even know if you are using WinForms, WPF or ASP.NET.

As this kind of communication-problem seems to happen quite frequently, maybe it would be a good idea to look for some exemplary, well written questions here to 1) link them in "How to ask a question" and 2) link them in your/our replies to questions that can't be interpreted. Like the exemplary article linked somewhere in the article-writing-guides. I just had a quick look for showing one to the inquirer of this question but it seems they're a bit hard to find..

There is a sticky entry at the top of this forum entitled How to get an answer to your question[^], which few people read. And even though both Pete and Griff have tried to draw out some useful information, the OP seems incapable of understanding that we cannot guess what his/her problem is.

|

My idea is that some people might be more likely to get the idea how a question should look like when they see an examplary one, rather when being told they should be more specific. I'm aware that there's the "How to get an answer"-sticky and that few people actually read it (like in any forum..) but at least then Pete and Griff could just have told him "look at this one, this is how a question should look like" instead of multiple attempts to convey the idea.

Come on, these people are supposed to be professional developers. If they cannot make the effort to do something this simple then they are not likely to last very long.

I would happily agree with you, but 
While these forums might be intended to be used by professional developers to ask questions, to me it seems that the majority of inquirers is very unexperienced. And it seems to be tolerated, otherwise questions like these could be just closed instead of trying to make sense of it. So if it's tolerated, wouldn't it make sense to supply this kind of "illustrative material"?

Experienced or not, they should possess enough intelligence to describe a problem in proper detail. It's not just about explaining the problem, it's also about making the effort for themselves rather than just posting a vague sentence, or dumping some code and saying "please fix it".
|
|
|
|

I completely agree with you. I'm not trying to justify the inquirers of these questions; just presenting an idea that could possibly make everybodys participation here a bit easier. I don't think Griff or anybody else takes enjoyment from repeating himself over and over. The link in Dave's signature is very good.

Hey, if you think we are being picking asking you about your code you're not thinking about how picking the computer is! If you can't describe the code and problem to us, you have no hope at all of describing it to computer!
