开始一个线程处理读取的文件并且更新到listbox中：
        //处理数据:
        private void StartBrowser(string path)
        {
            UpdateFolderPath invoker = new UpdateFolderPath(DoUpdateFolder);
            this.Dispatcher.Invoke(invoker, path);

            UpdateFolder = new Thread(GetFiles);
            if (UpdateFolder.ThreadState == ThreadState.Running)
            {
                UpdateFolder.Abort();
            }
            UpdateFolder.Start();

        }

        protected void DoUpdateFolder(string path)
        {
            this.tbk_ForderPath.Text = path;
            this.folderPath = path;
        }

        private void GetFiles()
        {
            if (this.listItem.Count > 0)
            {
                this.listItem.RemoveAll(delegate(object s) { return s == null; });
            }
            try
            {
                files = Directory.GetFiles(folderPath, "*.*", SearchOption.AllDirectories);

                    UpdateListUI update = new UpdateListUI(DoAddItem);

                    this.Dispatcher.Invoke(update, fi);

                }
            }

                img.Width = 25;
                img.Source = icon.ToImageSource();
                Run r1 = new Run(fileInfo.Name + "(" + fileInfo.Length + " Byte)");
                Run r2 = new Run(fileInfo.FullName);

                dp.Children.Add(tbk1);

                this.listbox1.Items.Add(dp);
                this.listbox1.ScrollIntoView(this.listbox1.Items[this.listbox1.Items.Count - 1]);
