How do I check folders for write-protection?

Question

I'm a newbie to programming, and have only been working with standard console programs written with C#.

I am currently on an internship, and I've been asked to design a little Tool for them.

To be fair, the assignment is way over my ahead, and nothing like what I have previously made with C#.

The Tool basicly has to do the following:

User choses a folder to be searched.

Program checks all files in the folder, and all sub folders, and checks the Write-protection if not already checked.

Program sets read-only attribute on all files, if there is not currently.

If this is not the place to search for help, please disregard my question.

Thanks for reading.

Answer 1

This is pretty much a copy paste from this thread:

The complete code should look something like:

    public void SetAllFilesAsReadOnly(string rootPath)
    {
        //this will go over all files in the directory and sub directories
        foreach (string file in Directory.EnumerateFiles(rootPath, "*.*", SearchOption.AllDirectories))
        {
            //Getting an object that holds some information about the current file
            FileAttributes attr = File.GetAttributes(file);

            // set the file as read-only
            attr = attr | FileAttributes.ReadOnly;
            File.SetAttributes(file,attr);
        }
    }

Following your comments, Just for better understanding, let's break it into bits and pieces:

once you have the file path, create the file attribute object:

var attr = File.GetAttributes(path);

For the following, you might want to read a bit about enum flags and bitwise

this is how you set as Read only:

// set read-only
attr = attr | FileAttributes.ReadOnly;
File.SetAttributes(path, attr);

this is how you un-set as Read only:

// unset read-only
attr = attr & ~FileAttributes.ReadOnly;
File.SetAttributes(path, attr);

And for getting all files you can use:

 foreach (string file in Directory.EnumerateFiles(path, "*.*", SearchOption.AllDirectories))
    {
        Console.WriteLine(file);
    }

Answer 2

You can check it via

FileAttributes attr = File.GetAttributes(path);
            if(attr.HasFlag( FileAttributes.ReadOnly ))
            {
             //it is readonly   
            }

Answer 3

This MSDN thread introduces the following code sample for acquiring folder permissions:

DirectorySecurity dSecurity = Directory.GetAccessControl(@"d:\myfolder");
foreach (FileSystemAccessRule rule in dSecurity.GetAccessRules(true, true, typeof(NTAccount)))
{
 if (rule.FileSystemRights == FileSystemRights.Read)
 {
  Console.WriteLine("Account:{0}", rule.IdentityReference.Value);
 }
}

Answer 4

Check out DirectoryInfo. In particular the Attributes property.
