Question

I have a C# code which creates a folder and sets some permissions on it. Here is the code sample:

static void Main(string[] args){

        Directory.CreateDirectory("C:\\vk07");
        DirectorySecurity dirSec = Directory.GetAccessControl("C:\\vk07");

        dirSec.AddAccessRule(new FileSystemAccessRule("INTRANET\\fGLBChorusUsers", FileSystemRights.ReadAndExecute, AccessControlType.Allow));            
        Directory.SetAccessControl("C:\\vk07", dirSec);
}

When I check the permissions set on the folder created above, instead of having Read and Modify (which is what I have set in the code), it shows only “Special Permissions” as checked.

Please can some one help me with this? I am new to ACL, so don’t understand it very well.

FileSystemRights.ReadAndExecute doesn’t allow you to modify. This is for read-only.
You would need FileSystemRights.Modify for the full range.
You may want to check out for the options available.

here is an example of the above:

String dir = @"C:\vk07"; 
Directory.CreateDirectory(dir); 
DirectoryInfo dirInfo = new   DirectoryInfo(dir); 
DirectorySecurity dirSec = dirInfo.GetAccessControl(); 
dirSec.AddAccessRule(new FileSystemAccessRule("INTRANET\\fGLBChorusUsers",FileSystemRights.Modify,AccessCo‌ntrolType.Allow)); 
dirInfo.SetAccessControl(dirSec);
