Hi
I have a drive called Z: which is present in a lan and it should be accessible to all systems connected in the LAN.

When I create a folder in Z:, I want to set the permissions (ie) read, hidden, etc...

I am creating the directory using System.IO.Directory.CreateDirectory() method.

I tried the following methods to set the permissions, but hasn't work for the network drive.

public static void AddDirectorySecurity(string FileName, string Account, FileSystemRights Rights, AccessControlType ControlType)
{
    try
    {
       //http://msdn.microsoft.com/en-us/library/system.io.directory.setaccesscontrol.aspx
       // Create a new DirectoryInfoobject.
       DirectoryInfo dInfo = new DirectoryInfo(FileName);

       // Get a DirectorySecurity object that represents the
       // current security settings.
       DirectorySecurity dSecurity = dInfo.GetAccessControl();

       // Add the FileSystemAccessRule to the security settings.
       dSecurity.AddAccessRule(new FileSystemAccessRule(Account, Rights, ControlType));

       // Set the new access settings.
       dInfo.SetAccessControl(dSecurity);
    }
    catch (Exception e)
    {
       MessageBox.Show(e.Message.ToString());
    }
}

public static void RemoveDirectorySecurity(string FileName, string Account, FileSystemRights Rights, AccessControlType ControlType)
{
    // Create a new DirectoryInfo object.
    DirectoryInfo dInfo = new DirectoryInfo(FileName);

    // Get a DirectorySecurity object that represents the
    // current security settings.
    DirectorySecurity dSecurity = dInfo.GetAccessControl();

    // Add the FileSystemAccessRule to the security settings.
    dSecurity.RemoveAccessRule(new FileSystemAccessRule(Account, Rights, ControlType));

    // Set the new access settings.
    dInfo.SetAccessControl(dSecurity);

}

How do I set the permissions using c# 3.0? Any help would be appreciated.

Thanks in advance,
Pawan.

Is your network folder hosted on an NTFS share? This won't work if it's some other share (like consumer NAS devices), or even most versions of Samba.
Even if your share is NTFS, you cannot set permissions on the root of the share (these are controlled by the share itself, and the permission are quite simple: read, read/write or no access.)
You can only set permissions on subdirectories and files below the root of the share.
