C# DirectorySecurity SetOwner on subcontainers and objects

Question

I am trying to change ownership of a windows folder and everything inside it. Basially I am trying to check the box that would be there if you did this manually in windows that says "Replace owner on subcontainers and objects". This will need to work over a network share path. I am able to get 1 folder deep but then it just stops there. This does not include the base folder changing either.

 foreach (string directory in Directory.GetDirectories(dirPath))
            {
                var di = new DirectoryInfo(directory);
                IdentityReference user = new NTAccount(Login.authUserName.ToString());
                DirectorySecurity dSecurity = di.GetAccessControl();
                dSecurity.SetOwner(user);
                di.SetAccessControl(dSecurity);
            }

You can use Directory.GetDirectories with SearchOption.AllDirectories in order to recurse.

But it seems easier to just get the DirectoryInfo di objects directly using DirectoryInfo.GetDirectories, which has the same and more recursive options.

IdentityReference user = new NTAccount(Login.authUserName.ToString());

var root = new DirectoryInfo(dirPath);
foreach (var di in root.GetDirectories("*", SearchOption.TopDirectoryOnly).Prepend(root))
{
    var dSecurity = di.GetAccessControl();
    dSecurity.SetOwner(user);
    di.SetAccessControl(dSecurity);
}
