I'm not sure your observations are correct. Could you repeat it thoroughly and report exact steps to reproduce the problem?

We can discuss anything only if you provide exact steps to reproduce it. I hope you will cope with English (but please, don't use "text speak" like "tsk", etc.)

"Environment.CurrentDirectory" does not mean that the current working directory is the same as that path to your executable.

This is the problem: current directory is never guaranteed to be anything certain at all. It can be anything, as it depends on how user starts it.

So, i need use direct path instead Environment.CurrentDirectory
So, i will have a new problem,if i copy my app to new machine, the direct path will change, how can change path app in the new machine ?

Sergey Alexandrovich Kryukov 2-May-13 10:07am

Never rely upon CurrentDirectory, don't mix it up with assembly location.
I don't see a problem with new machine: when you or some code copies the assembly files, the target path is known, right? So, what's the problem? Main thing is: never ever hard-code the path names...

No, you would need to create a short but complete sample project and post it all using "Improve question". If you shorten up the project just to focus on one issue, it's usually possible.

Please see the comment by ThePhantomUpvoter and my last comment to the question: current directory can be anything; it depends on the user's way to start your application. You can never rely on that. To see how you can find out some directories, please see my comprehensive answers on this topic:
How to find my programs directory (executable directory),
How to find my programs directory (current directory, "special folders").
