## 场景 ##

Winform中选取指定文件夹，并获取该文件夹下所有文件名，不包含子文件夹。考虑子文件夹可以使用递归实现。

## 实现 ##

1、新建Winform项目，页面添加Button和TextBox

2、选择扫描路径按钮实现

//选择扫描文件路径
            private void select_scan_path_Click(object sender, EventArgs e)
            {
                FolderBrowserDialog path = new FolderBrowserDialog();
                path.ShowDialog();
                this.textBox_selected_scan_path.Text = path.SelectedPath;
            }

3、扫描文件按钮实现

private void button_scan_file_Click(object sender, EventArgs e)
            {
                string scanDirectoryPath = this.textBox_selected_scan_path.Text;
                if (String.IsNullOrEmpty(scanDirectoryPath))
                {
                    MessageBox.Show("扫描文件路径不能为空");
                }
                else
                {
                    //指定的文件夹目录
                    DirectoryInfo dir = new DirectoryInfo(scanDirectoryPath);
                    if (dir.Exists == false)
                    {
                        MessageBox.Show("路径不存在！请重新输入");
                    }
                    else
                    {
                        this.textBox_scan_file_list.Clear();
                        //检索表示当前目录的文件和子目录
                        FileSystemInfo[] fsinfos = dir.GetFiles();
                        //遍历检索的文件和子目录
                        foreach (FileSystemInfo fsinfo in fsinfos)
                        {
                            this.textBox_scan_file_list.AppendText(fsinfo.Name);
                            this.textBox_scan_file_list.AppendText("\r\n");
                        }
                    }
                }
            }
