I have a program where I can make folders and put files into them but I want to know which folders already exist.
As example :
In my application folder bin/debug, I have 2 folders, folder 1 and folder 2.
So when I run my program I want the name of those 2 folders to be listed into a listview so I can see which folder already exist.
Anybody knows how I can do that?
Thx!
if you know about the binding, the rest is simple:
By this you get all dictionaries in your execution (bin/debug) directory
DirectoryInfo directory = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory);
DirectoryInfo[] subdirectory = directory.GetDirectories();
List<string> directoryNames = subdirectory.Select(subdir => subdir.Name).ToList();
This way you'll get all folder in your execution directory that exist, no matter of the name. You can however check if the name is folder1 or folder two, on you subdictonaries if you'd like to

Is it good practice to save the Images/Files in the current working directory in c# project. Or it is better to save them as other project files and folders independent of the program execution.
Better to use a safer place instead execution location. Take a place where the user has file write access like Documents, AppData etc. Because the application might be run in the different place where in some places possible user has no file write access, then you won't be able to save any images/files there.
This is an opinion based question. But still I will share my opinion.
You can keep all the images within a specific folder within your project. Such as an Image folder or whatever name you would like to give it.
While adding the item to your project, you can click on properties of the image and specify the Build Action to Resource in the properties window.
Specify the UriSource property as :
UriSource="/images/abcd.png"
That URI is effectively a Resource File Pack URI,and the prefix would be automatically added, so you need not worry about copying the image file to output directory.

I am using this code
axWindowsMediaPlayer1.URL = #"c:\myvideo.avi";
but when the video file containing folder changed this code is not working.i need to set an permanent URL even though the file containing folder is changed.
You can’t find the file if it’s location was changed. Imagine if the user moved it to another drive or permanently deleted it - what would you do then?
If you’re changing folder within your application then of course you can track where the file was placed and correspondingly change the path. But if the path was changed outside of your app you can’t do anything with it.

I was trying to create a zip file programmatically in C#.
Unfortunately the below line keeps throwing error for some unknown reason.
Package zip = ZipPackage.Open("E:\\Logs",System.IO.FileMode.OpenOrCreate,
System.IO.FileAccess.ReadWrite);
Access to the path "E:\Logs" is denied.
I tried some diff piece of code, but I had the same issue
FileStream fs = File.Create("E:\\Logs");
Not sure what could be the reason. Appreciate if this could be resolved.
First you must use \\ instead of \.
Second, Open method accept a file name. So you must use it like this:
Package zip = ZipPackage.Open("D:\\a.zip",System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.ReadWrite);
It gives you the answer in the error, you don't have access to that area, you're trying to create a file in the root directory of your drive and you don't have the user rights to do that, it's the same if you don't do it programatically, if you try to create a file named logs at the root of C on any modern version of Windows you will get told you need to elevate to administrator access.

I have a 10 GB folder(myfolder) that has lot of files used in an web application. Every week, this gets recreated in a different folder(mynewfolder). I want to move old files to a diff directory and move newly created ones to the right folder without user noticing (or very less down time). I can either do it in C# program or a batch file. Which is a better option? How can I do it in batch file?
C:\myfiles\myfolder --Existing
C:\myfiles\mynewfolder -- newly created
Thanks
MR
Huh? Just rename myfolder as mynewfolder. It doesn't take any time at all regardless of how much data or how many files are in there.
rename myfolder mynewfolder

hi i am creating a c# application that monitor the files that has been copied , the aim of program is to alert user that there is a file has been copied , i know the file system watcher class , but it has only 4 events , change or create or delete or rename , is there a way to know if file has been copied in or out of system ?
When a file is copied into the system you will also get a change or create event. But if it is simply accessed (which is what happens when it is copied) FileSystemWatcher is of no use.
You can use Auditing file and folder access feature of Windows.
The task makes no sense. First of all, there's no "copy" operation on the OS level. Copy is a sequence of open/read/close (source) + create/write/close (dest) operations. Now, even if such operation existed (eg. Explorer has such concept), what about archiving the file and then copying out the archive?
