I am trying copy file to mapped network location.
If I try to do it manually everything is working OK.
By running following code I don't get any exceptions but I not get the code at the needed location.
string _sharedLocation = #"C:\Users\pddd\AppData\Roaming\Microsoft\Windows\Network Shortcuts\system-tests";
if (Directory.Exists(_sharedLocation) && File.Exists(#"c:\\Automation\\Tests\\Test1\\events.json"))
{
File.Copy(#"c:\\Automation\\Tests\\Test1\\events.json", Path.Combine(_sharedLocation, "events11.json"), true);
}
Any suggestions with that issue.
looking at the _SharedLocation variable, it's on location: "...\Windows\Network Shortcuts\..."
I'm just guessing here, but are you tring to refer to a shortcut to a network folder, rather than a network folder?
This will never work:
File.Copy(myOriginalFile, "C:\...\MyShortcutToANetworkFolder\myFile.txt");
Why not? Because a shortcut is basically a file, not a folder (it's more complicated than that, but I'm keeping it simple for argument's sake). You cannot put a file (or anything else) into a shortcut. The only thing you can do with a shortcut is open it.
You need the actual network folder path.
This will work:
File.Copy(myOriginalFile, "\\myServer\myFolder1\myFolder2\myFile.txt");
It seems that the target path _sharedLocation also refers to a local path, not a remote path.
I guess you sharedLocation path is not valid.
If you write #"c:\" it will refer your local drive on which the code is running
so Please correct it
Problem: Your shared Path refers to C: drive of same machine. Possibly you are referring to the shortcut of mapped network location.
string _sharedLocation = #"C:\Users\pddd\AppData\Roaming\Microsoft\Windows\Network Shortcuts\system-tests";
It should be:
string _sharedLocation = #"\\ComputerNetworkIdentity\SharedFolder\pddd\AppData\Roaming\Microsoft\Windows\Network Shortcuts\system-tests";
Shared computer can be located using \\ComputerName.
You must have Write permission on shared folder.
Simple Way Locate A Shared Folder:
Open Run dialog.
Type computer name with preceding backslash e.g. \\ComputerNetworIdentity
Locate the folders shared by the network computer.

sorry first time user and currently learning c# at uni, i'm working on an assignment and i'm trying to get the file path to work on the memory stick as that's what i need to hand it in on, thanks many regards
I'm not completely sure what your question is by I think what you're talking about is absolute vs relative paths. If you use an absolute path like "C:\users\yourname\blalba\project\stuff", then it's obviously only going to only work on your computer. However, you mostly all of the time want to use relative paths. Relative paths have the root directory of the build output files for your project; where your .exe file is built for your project. This is usually in "projectdir\bin\debug" or "projectdir\bin\release". So if you put for example a file called 'test.txt' in that directory, you can simply put the relative path "test.txt" instead of "C:\users\yourname\blalba\project\bin\debug\test.txt". If you were to put 'test.txt' in the project directory, you can use the relative path "....\test.txt". "..\" means navigating one step back.
The path to the directory containing the files you are looking for is "F:\Mod005244, 1715840". The "1715840 JH" is just the name of the drive. You access different drives via the drive letter. In this case, the drive letter "F" was assigned to your flash drive.
I would suggest making the file path configurable or request input from the user of the program as the drive letter of a flash drive will not always be "F". There are even classes (such as FileBrowserDialog) that will open a graphical file browser dialog and prompt the user to navigate and select a file.
I have an Image Path which is of D: drive and I want to display that Image on my Image Control of asp.net.So, how to provide file path to Image.ImageUrl?
"D:/Folder/001_001.jpg"
I tried with server.MapPath() method but doesn't work.
If you're deploying in IIS, you could create a virtual directory Images that would point towards D:/Folder, then you could set your ImageUrl to ~/Images/001_001.jpg.jpg.
An alternative solution could be to create a symlink between the two folders. You would run something like the following in cmd mklink /D ""D:/Folder" "[YouProjectPath]/Images", then set your ImageUrl to ~/Images/001_001.jpg.jpg. I would stay away from this though as it would only work on a machine where the project lives in the exact same path as yours.
You can make local path as following "file:///D:/Folder/001_001.jpg".
However, it's strongly not recommended to use this practice even if your site is planned to stay on your local computer only and will never been deployed to real Internet. You should copy / upload the file to your site's subdirectory 'Images' and then use the relative path '~/Images/001_001.jpg'.
I have a .txt file that I need to read in my program. For the moment I have the directory hardcoded as such:
file = new StreamReader(#"C:\Users\<username>\Documents\File.txt");
However that will (obviously) not work on any other PC that does not have that access to altering the code, or (by some strange happenstance) the same directory as the original code.
How can I get the full file path to set it in my program using C#?
You could create the file in their Application Data directory (they could still find it if they wanted to, but at least it wouldn't be as obvious as the My Documents folder).
When you want to access it, use the Environment class. There are methods for locating special folders for the current user, without resorting to hard-coded paths:
var filePath = Path.Combine(Environment.GetFolderPath(
Environment.SpecialFolder.ApplicationData), "File.txt");
Option 1:
Application.StartupPath can be used for the purpose.
It gets the path for the executable file that started the application, not including the executable name.
Keep File.txt with your executable.
Option 2:
Use Environment.SpecialFolder.ApplicationData
It gives directory that serves as a common repository for application-specific data for the current roaming user.
NOTE: If you want to restrict the user to look into the contents of File.txt then you might need to encrypt the contents.
I am developing website using Visual Studio 2010. I am trying to save a file in a path. It works fine localhost.
But the same code is not working in IIS. It shows the following error
Exception Details: System.IO.DirectoryNotFoundException: Could not
find a part of the path 'C:\Inetpub\wwwroot\Vendor\cn.jpg'.
Could not find a part of the path 'C:\Users\shashank\Desktop\ab.csv'.
Here is the code:
protected void btnImportFile_Click(object sender, EventArgs e)
{
sArReportText = File.ReadAllText(txtFilePath.Text.Trim());
// Set the report Properties to insert Report information
SetProperties();
}
You might also be experiencing what I am: that the directory name contains some unusual characters. In my case,
Could not find a part of the path 'C:\Web\metBoot\wild iis\DigiCert© Certificate Utility for Windows_files'.
That copyright sign is the issue.
So using concepts drawn from Obtaining the short 8.3 filename from a long filename, I convert my paths to short form first, then use that to get my list of files.
StringBuilder sf = new StringBuilder(300);
int n = GetShortPathName(sourceFolder, sf, 300);
if (0 == n)
{
tk.write(Marshal.GetLastWin32Error().ToString());
continue;
}
...
IEnumerable<string> fileGroup = Directory.EnumerateFiles(sf.ToString(), ext);
Consider how you're launching VS too. Counter-intuitively I run into this problem only when I'm running VS in Administrator mode. Possibly a group policies thing.
This may be because, you are not having the specified file in web server, or you may be used an incorrect path. Specify the exact folder and filename as how it is stored in the web server. use HttpContext.Current.Request.ApplicationPath or Server.MapPath to specify the correct location where your desired file lies. And also make sure that you have given read and write permissions for this specific file and its folder.
You need to have permissions set in iis to allow files to be saved in the folder. Basically your uploaded files should be saved inside a separate folder present inside your root directory.
In order to access, create and delete files on the server, must have rights.
Like in my project I am using Impersonator class to access various files and folder from the server.
Otherwise it will throw an exception.
You could use code impersonation:
http://csharptuning.blogspot.com/2007/06/impersonation-in-c.html
http://www.codeproject.com/Articles/14358/User-Impersonation-in-NET
regardless, whomever you use as the impersonation must be able to read/write to the location that is being saved to. We use this method in applications for delete/create folders across network. Even if App_Data is best practice, it may be a business requirement to access the documents outside of that folder.
You can also set impersonation on IIS.
I also notice that your function is called btnImportFile. You may want to look into FileUpload control if you are uploading a file, which allows you to get the byte array of the file and save as needed. https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload%28v=vs.110%29.aspx. You might still need to use Server.MapPath or HttpContext.Current.Request.ApplicationPath depending on your needs.
It's usually best practice to use the App_Data folder to save files to.
Take a look here, Working with files, for a tutorial.
I am using WritePrivateProfileString in c# (through DllImport) to store paths taken from textboxes on the interface. And the .ini file name is hardcoded in my application
string ini_file = ".\\config.ini";
However, when the file writing happens, the configuration file is written to the first path taken from the interface instead of writing it to the exe directory. Which is quite odd.
Debugging shows that the values are sent correctly to the WritePrivateProfileString but it still is written to the wrong location. Anyone knows why is that happenening?
I'd guess that something is changing the working directory of your process, most likely your code in the process. Note that the documentation has this to say:
If the lpFileName parameter does not contain a full path and file name for the file, WritePrivateProfileString searches the Windows directory for the file. If the file does not exist, this function creates the file in the Windows directory.
Now my guess is that this applies if you supply just a file name. Because your file name starts with . I believe that will force the function to start from the current working directory.
Having said all of that, and no matter what the cause of the problem is, you should use a fully-qualified path in order to make sure the file is written where you want it to be written. Whenever you want the file to go in a specific directory, it's always easiest to force that by using fully-qualified paths.
You can find the path to your executable using Application.ExecutablePath and then remove the file name part.
Another point to make is that the same directory as the executable may be a bad choice. If your program is installed under the Program Files directory then the directory which contains the executable will not be generally writeable. I think you should consider using a directory under in the user profile. Look for one of the Environment.SpecialFolder values.
Further to David Heffernan's answer - you can use
Path.GetDirectoryName(Application.ExecutablePath);
to safely get just the running application's folder part.
If you're in a dll rather than an executable, you can use
Path.GetDirectoryName(Assembly.GetAssembly(typeof(MyClass)).CodeBase);
Both require System.IO, and were originally posted here. Second example also requires System.Reflection).
Application data files are supposed to be written to the LocalApplicationData special folder.
string path = System.Environment.GetFolderPath(System.Environment.SpecialFolder.LocalApplicationData);
You typically will not have permissions to write into the Program Files folder etc.
