get all sub directories and files from those directories

What i am trying to do is get a lst of files in all directories from the specified directory root.

here is my code, but it only returns one directory and then doesnt print the files for the main directory.

  private void getFilesInSubs()
        {
 MyOrionDS.FileInfo.Clear();
            string path = textBox1.Text;

            DirectoryInfo subdirs = new DirectoryInfo(path);
            DirectoryInfo[] dirs = subdirs.GetDirectories("*");
            foreach (DirectoryInfo directory in dirs)
            {
                System.IO.DirectoryInfo dInfo = new System.IO.DirectoryInfo(directory.FullName);
                if (tbxFileType.Text.Length == 0)
                {
                    pattern = "*.*";
                }
                else
                {
                    pattern = "*." + tbxFileType.Text;
                }
                System.IO.FileInfo[] fInfo = dInfo.GetFiles(pattern);
                foreach (System.IO.FileInfo fi in fInfo)
                {
                    //string fileInfoStuff = "";
                    string fileName = fi.FullName;
                    //string fileversion = "";
                    DateTime creationTime = fi.CreationTime;
                    DateTime LastModifyDate = fi.LastWriteTime;
                    System.Diagnostics.FileVersionInfo myFileVersionInfo = System.Diagnostics.FileVersionInfo.GetVersionInfo(fileName);
                    //MessageBox.Show(myFileVersionInfo.ToString());
                    //fileInfoStuff = fi.Name + " | " + creationTime + " | " + myFileVersionInfo.FileVersion;

                    OrionDataSet.FileInfoRow newFileInfoRow = (OrionDataSet.FileInfoRow)MyOrionDS.FileInfo.NewFileInfoRow();

                    newFileInfoRow.FileName = fi.FullName;
                    newFileInfoRow.LastModifyDate = LastModifyDate;
                    newFileInfoRow.CreateDate = creationTime;
                    newFileInfoRow.VersionNumber = myFileVersionInfo.FileVersion;

                    MyOrionDS.FileInfo.Rows.Add(newFileInfoRow);
                    MyOrionDS.FileInfo.AcceptChanges();



                    //lbxPreview.Items.Add(fileInfoStuff);
                }
            }

            dataGridView1.DataSource = MyOrionDS.FileInfo;
