在C＃中创建没有只读属性的目录

Question

When I try to do that:

Directory.CreateDirectory([folderPath]);
File.CreateText([folderPath]);

I had the exception -

System.UnauthorizedAccessException was unhandled by user code
  HResult=-2147024891
  Message=Access to the path 'C:\[folderPath]' is denied.

  InnerException:

File Explorer show me:

Attributes: [tristate/indeterminate checkbox] Read-only (Only applies to files in folder)

But Debug.WriteLine(CurrentContestDirectory.Attributes.ToString()); Show me - Directory . And not the readonly attribute!

I looked for "Removing read only attribute on a directory using C#" in Google, but all answers don't help me. What I need to do?

All code runs on my local machine with Windows 8. Admin account. And if I uncheck readonly attrinute manually, after code run it toggle back.

It's simple console app.

Now I manually create folder. It's have read-only by default.

attrib -r C:\\new /s in cmd not working!!!

And if I uncheck read-only manually and click OK then if I click Properties - read-only come back

Answer 1

try with this code:

 Directory.CreateDirectory(@"c:\newfolder");
 File.CreateText(@"c:\newfolder\textfile.txt");

Answer 2

I would verify that your application running this code itself has proper rights in Windows. For instance, right click the application and click "Run as administrator"

Answer 3

File.CreateText([folderPath]);

is probably wrong. Any attempt to create a file (or open a stream) when the file path is actually a folder path will end with

UnauthorizedAccessException

The exception is very misleading and ask you to look in all the wrong places. Been there, seen it.
