If you wanted to remove the readonly attributes using pattern matching (e.g. all files in the folder with a .txt extension) you could try something like this:

Directory.EnumerateFiles(path, "*.txt").ToList().ForEach(file => new FileInfo(file).Attributes = FileAttributes.Normal);

You can try this : iterate on each file and subdirectory :

public void Recurse(DirectoryInfo directory)
{
    foreach (FileInfo fi in directory.GetFiles())
    {
        fi.IsReadOnly = false; // or true
    }

    foreach (DirectoryInfo subdir in directory.GetDirectories())
    {
        Recurse(subdir);
    }
}

Use File.SetAttributes in a loop iterating over Directory.GetFiles

foreach (string fileName in System.IO.Directory.GetFiles(path))
{
    System.IO.FileInfo fileInfo = new System.IO.FileInfo(fileName);

    fileInfo.Attributes |= System.IO.FileAttributes.ReadOnly;
    // or
    fileInfo.IsReadOnly = true;
}
