Default Folder listing and permissions

I have an aspx page that is displaying the contents of a directory on my web server. Each folder has different permissions based on user log ons. My problem is this. . .
I do not want to display folders in which users do not have permission to. Is there a way to do this?

Here is the code . . .

public void Page_Load(object s, System.EventArgs ea) {
    try {
        string strDir = Request.QueryString["d"];
        string strParent = strDir.Substring(0,strDir.LastIndexOf("\\"));
        strParent += strParent.EndsWith(":") ? "\\" : "";
        upLink.NavigateUrl = "browse.aspx?d="+strParent;
        txtCurrentDir.Text = "Address: <b>"+strDir + "</b>";
        DirectoryInfo DirInfo = new DirectoryInfo(strDir);
        DirectoryInfo[] subDirs = DirInfo.GetDirectories();

        FileInfo[] Files = DirInfo.GetFiles();
        txtListing.Text = "<table>";
        for (int i=0; i<=subDirs.Length-1; i++) {

            txtListing.Text +="Check auth here";

            txtListing.Text += "<tr><td><img src='images/folder.gif'><a href='browse.aspx?d="+subDirs[i].FullName+"' class='entry'>"+subDirs[i].Name+"</a></td><td valign='bottom'>"+subDirs[i].LastWriteTime+"</td></tr>";
        for (int i=0; i<=Files.Length-1; i++) {
            txtListing.Text += "<tr><td><img src='images/file.gif'>"+Files[i].Name+"</td><td valign='bottom'>"+Files[i].LastWriteTime+"</td></tr>";
        txtListing.Text += "</table>";


    catch (UnauthorizedAccessException ex){


    catch (Exception e){

        txtListing.Text = "Error retrieving directory info: "+e;
