如何循环文件夹和子文件夹中的文件

Question

我在编写文件夹和子文件夹中的文件时遇到问题。

例如： - test是主文件夹

1）C：\ test \

我希望阅读和编写子文件夹文件

2）C：\测试\ 2011年12月5日\ 12-05-2011.txt

3）C：\测试\ 13-05-2011 \ 13-05-2011.txt

4）C：\测试\ 14-05-2011 \ 14-05-2011.txt

我的代码是。

                        }
                    }
                }
                catch (Exception)
                {
                    //MsgBox("Error" & ex1.Message)
                }
                xyz++;
            }
        }
        catch (Exception)
        {
            //MsgBox("Error" & ex.Message)
        }
    }

我收到错误错误是访问路径'C：\ test'被拒绝。

任何人都可以说我需要在此代码中更改内容。
