I'm trying to create an XML in an UNC path, using C#, but I'm getting the error "Access denied".
What I'm trying to do is:
doc.Save(#"\\someshare\somefolder\anotherfolder");
(the rest of the code is correct, I already tried on a local folder)
I guess I'll need to use some class to authenthicate on the share. But I don't know which. Could you tell me which is?

I have simple code
using (FileStream fs = File.Create(#"newfile.txt"))
{
}
And if I give the path "E:\newfile.txt" I get the error System.IO.IOException: 'The media is write protected.'
If I give the path "C:\newfile.txt" I get no error but no file creation, even if I give the path "C:\Users\Me\Documents\newfile.txt" I get no error and no file creation.
Are these errors related, I have written to USB devices no problem before, and my C drive should not be restricted and surely the Users folder isnt restricted at all.
What am I missing?
Perhaps this might work:
string path = #"C:\Users\Me\Documents\newfile.txt"
File.AppendAllText(path,new[] {"Your text goes here"});
This will create the file if it does not exist or write to the existing one.

I'm trying to make an app to "Quick Format" an usb flash drive, it's all good until i put a file without extension (eg: helloworld).
I'm using Directory.Delete(dir, true); to achieve my goal, but recursive delete is interpreting helloworld as a directory instead of interpreting it as a file, so it throws Access to the path 'helloword' is denied.
Any help will be appreciated!
I ran my program in C# that suppose to create and write a file in C:\, but an error occurred saying that access to the path C:\mytextfile.txt is denied. Is there any code that will give the user permission in C:\?
Yes by using the manifest http://www.codeproject.com/Articles/66259/Requesting-Admin-Approval-at-Application-Start or run as different account which has sufficient rights
You need to run the code as an administrator. You don't need C# code for this, you need to change how you're running the code.
However, I suspect that you're trying to do something wrong. I'd guess that you're trying to store some data locally, and are using the root of C: for simplicity, when you should actually be using the standard libraries to locate the users folder or to get a temporary file.
e.g. Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
(for other folders, use Intellisense to look at the other SpecialFolder children.)
In my .net windows application am using a xml file .
But after installing the application by creating setup, while I am running that 'Access Denied' to that xml file message is shown.
I am using System.IO.File methods for doing file operations.
If any body knows the solution pls share.
Write access to program directory has been more and more restricted (starting with XP/Vista) since that is a secruity risk!
I would suggest to have the "base version" of that file readonly in your program directory...
Upon start of your app you check whether it is present in ApplicationData or LocalApplicationData or CommonApplicationData - (to get the real path at runtime use Environment.GetFolderPath). If it is not there then copy it there - in those locations your application has write access by default with no need for Administrator rights.
Program Files folder has limited access and can be modified by Administrator account. I would suggest you to save your xml file in *C:\Users\YourPCName\AppData\Local\YourAppFolder* .
This way you will be able to access and modify the file
I had this problem once so I used Isolated Storage and that fixed my problem. It may or may not work for you depending on the nature of your situation, but here's a quick tutorial on how to use it:

Getting this strange error.
In C#, I write to a file (txt) whose location I provide at run-time.
The problem is that whatever location I provide, It returns an error: Access to "..path.." is denied.
I checked the permissions, but the required permissions are set.
My code snippet
folderBrowserDialog.ShowDialog();
StreamWriter path = new StreamWriter(folderBrowserDialog.SelectedPath);
.
.
.
Any known issues or something I am missing?
Thanks
You should pass a file name to StreamWriter. It looks as if you're passing a folder name.
