Unable to copy file - access to the path is denied_问答_开发者

I am using Visual Studio 2005. After taking code from version control first, the c#.net application runs correctly. But, after doing some modifications, when I build I am getting the following error:

Error 383 Unable to copy file "..\root\leaf\Bin\Debug\test.Resources.xml" to "Bin\Debug\test.Resources.xml". Access to the path 'Bin\Debug\test.Resources.xml' is denied. li.rollmodel

Does anybody know why this issue is occurring?

Edit I can see that my entire project source code folder is Read-only, and I am not able to remove the read-only property.

First, can anybody tell me how to remove the Read-only property for this folder? I have tried removing it but the read-only property persists. I tried from the version开发者_运维技巧-control side also and that did not work, either.

I solved this problem by deleting the contentious files from bin folder and rebuilding the project.

Just make sure that the folder is NOT Read-Only and rebuild the solution

I solved this problem: Close Visual Studio, open it again and load the solution, Rebuild your solution. My problem occurred using TFS and VIsual Studio 2010.

Kill process VBCSCompiler.exe and rebuild.

Run your Visual Studio as Administrator. Or you can add write permission to "Users" on the output folder

I stepped into this problem too.

First go and check if you have mapped your bin and obj folder to the Source Control program.

This may be turning your files from binaries folders into read only archives, which make impossible to visual studio to overwrite them when it compiles the code.

Go and remove the mapping from these folders, check the changes and try again.

My problem occurred using TFS(Team foundation server) and Visual Studio 2010.

Hope this helps someone.

In my case it was the antivirus which blocked the file.

In my case, avast anti-virus quarantined the [app-name].exe file that needs to be copied so from the avast app, I had to go to protection > Quarantine, click the menu button beside the file and click 'restore and add exception' as shown below

Unable to copy file - access to the path is denied

I use Visual Studio 2013. I faced this problem 2 times:

On first occasion, I was running Visual Studio without Administrator rights. So, I closed VS and started it using 'Run as administrator' option. This solved my problem.
On second occasion, I restarted VS many times, every time making sure that I am running it as an administrator. Also, I rebuilt solution many times. But, in spite of that I was getting error. After that, I removed the concerned file from the target location (the file was already present may be from the previous build at the location where it tries to copy to) and rebuilt the solution. After that, error went away and everything ran smoothly!

First go to location of the file. Then right click on the folder of the file -> Properties -> Unchecked Read Only Option and apply to files and its sub folders. It resolved my issue. Happy Coding!

This has reared it's head again in Visual Studio 2017, in this case the cause is the Application Insights process ServiceHub.DataWarehouseHost.exe.

There is a workaround discussed in the thread warning MSB3026: Could not copy "obj\Debug\netcoreapp1.1\src.pdb" to "bin\Debug\netcoreapp1.1\src.pdb", which is to add a pre-build event to the project to kill the process every time the project is built. Quoting from that link:

Right click properties on project

Choose properties

Build Events

Pre-build event command line

taskkill /IM ServiceHub.DataWarehouseHost.exe /F 2>nul 1>nul
Exit 0

Save and build

Can any body know why this issue is coming?

Looking at your response that you resolved your problem by manual copying, I would say that the code you were working on was made by some other user (with administrator privileges too) so it was locked to you. By performing copy --? paste, you made your OWN copy of the source with all access you required. The only thing to notice is that, in this case if this other developer will need to work on your copy, he/she will jump in pretty same problem you got before.

Old post, but this zombie is hitting VS 2017 (I haven't dug into why it's just "some" projects). In this case, it's not user permissions, rather IIS Express process is still using the files.

You'll see the icon in your task tray

Unable to copy file - access to the path is denied

Right Click
Exit
You should be able to rebuild without this annoying "permission denied" message.

This is also why "restarting Visual Studio" will "fix" the issue. Doing so, stops IIS Express.

Hth...

I re-added all of my non-.NET dependencies / references and it did the trick.

I resolved this issue myself. The problem was I had the solution opened in another place. After closing it it works

Had the same problem, but restarting Visual Studio every time was no option for me, as the issue occurs sometimes very often.

I handled it by installing Unlocker (tries to install any toolbar at installation, so don't forget to uncheck this), this application gives me fast access to rename/delete a locked ".xml"-File. I know that this only a workaround too, but for me it was the fastest solution to solve this problem.

Most of the answers I have seen are objectively exploring possible issues with the environment, which is probably correct for 99% of the people running into this issue (unable to copy file from ... to ... access is denied).

I thought I should share my experience for the 1% who ran into this problem due to misc reasons.

I wrote a batch file renaming program that i use to act on tens of thousands of files, and my AntiVirus interpreted it as trojan and auto quarantined it. Having this path sit in my AntiVirus' blacklist, visual studio can never copy the *.exe into the bin folder, hence resulting unable to copy .exe.

My resolution is to whitelist this path and the issue is resolve.

Cheers.

I created this problem when I added a new setup project to the solution, and then added files directly from the /bin/release folder of the main application project to the application files folder of the setup project. The source control of the setup project was consistently blocking me from completing a build of the main application project.

Solution: create a separate dump folder outside of any of the projects that will contain all the files to be included in the install, and add them from there. It's a pain because now I have to remember to copy all the files for each new install package. I might see if I can do something with post-build actions our an automated build to make the process smoother.

If you copy any files across to a solution, make sure the files are not in Read Only mode. Right click on file and uncheck the attribute option solved my problem.

I had the same error but I am using Perforce version control. Here's how I fixed it.

Closed Perforce P4V client
Restarted Visual Studio 2010 (might not be necessary)
Rebuilt the project, which succeeded
Felt exceptionally happy and disgusted at the same time

I also had same problem. I got error messages that related to cannot copy since access to path denied. In my case all my dll's and xml files and so on are place at D:\TFS\Example\Bin\Debug folder.

I right clicked on Bin folder and clicked Properties and saw that Read-only check box is checked under Attributes.

I un-checked Read only check box and cliked Apply and clicked OK on the new popup that is shown.

I went back to Visual Studio and build my solution which was giving me error messages.

Voilaa.. This time it build successfully without errors.

I donot know whether this is perfect but I did this to solve my issue.

Check Task Manager and make sure you don't have a devenv.exe process hanging. Kill the runaway process and try again.

Go to file's path then un-check read only checkbox of this file.

I know its an old thread but for those looking for answers, like me a few minutes ago, I recommend trying to restart your computer first. That alone fixed for me. Before could not even manualy copy to the folder.

Just right click on your MVC project and click on the clean option. I had a similar problem and cleaning the project before rebuilding resolved it for me.

I had also the same problem. I fixed it by unchecking the Read-only properties of root folder.

I also had this issue. Here's how is resolved this

Exclude bin folder from project.
Close visual studio.
Disk cleanup of C drive.
Re-open project in visual studio.
And then rebuild solution.
Run project.

This process is works for me.

I was able to resolve the problem by removing the target file which is complaining(in your example "Bin\Debug\test.Resources.xml") from bin folder of target web site and re build it.That fixed it for me.

I tried everything here, somehow deleting all the bin and obj folders in my project didn't work. Releasing the folders from other processes did nothing. Restarting did nothing. Removing read only from every file by unchecking it on the main folder didn't help.

Every dependency ended up adding themselves to the problem. Building directly in the dependencies' folder worked so I was confused. I was going to duplicate this question but I found something that worked.

You know what worked?

dotnet clean

Changing the output path worked for me in Visual Studio 2015. This should help - Changing the Build Output directory
