                case ePathTextBoxType.File:
                    this.ofd = new OpenFileDialog();
                    ofd.Filter = Filter;//类似："文本文档|*.txt";
                    this.ofd.Multiselect = true;
                    if (this.ofd.ShowDialog() == DialogResult.OK)
                    {
                        this.label1.Text = this.ofd.FileName;
                    }
                    break;
                    //打开的是文件夹。
                case ePathTextBoxType.Floder:
                    this.fbd = new FolderBrowserDialog();
                    if (this.fbd.ShowDialog() == DialogResult.OK)
                    {
                        this.label1.Text = this.fbd.SelectedPath;
                    }
                    break;

                default:
                    break;
            }
        }
