如何读取其中包含的子文件夹和文件

Question

我可以使用 BETALIB 阅读器读取文件夹文件，但是通过在文件夹浏览器对话框中给出路径来读取它的文件很大 我可以读取文件夹，但在该文件夹中有很多文件夹和文件我想读取子文件夹。

例如：- E:\EXE\ttd\ttd1\ttd2\bsem\f1.dat E:\EXE\ttd\ttd1\ttd2\MCDEX\f1.dat

我想通过在文件夹浏览器对话框中给出路径来读取文件 EX:E:\EXE

如果我选择路径 E:\EXE，它应该会读取其中包含的所有子文件夹和文件。

谁能告诉我我应该在代码中更改什么

    private void btnSourceBOMCX_Click(object sender, EventArgs e)
    {
        fbdSourceBOMCX.Description = "Please select BOMCX source folder";
        fbdSourceBOMCX.RootFolder = Environment.SpecialFolder.Desktop;
        if ((fbdSourceBOMCX.ShowDialog() != DialogResult.Cancel) || (fbdSourceBOMCX.SelectedPath != ""))
        {
            sourceBOMCX = fbdSourceBOMCX.SelectedPath;
            if (File.Exists(sourceBOMCX + "\\Master"))
            {
                txtSourceBOMCX.Text = fbdSourceBOMCX.SelectedPath;
                Interaction.SaveSetting ((new Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase()).Info.Title  , "RealTime Converter", "sourceBOMCX", fbdSourceBOMCX.SelectedPath); 
            }
            else
            {

            }


        }
    }

你可以使用System.IO类库DirectoryInfo和FileInfo类，逻辑如下

1) 创建两个处理目录的函数和一个处理文件的函数 2）在哪个目录读取函数读取验证项目是文件还是目录 3）如果项目是目录它递归地调用自己 4）如果项目是文件，则将其发送到文件处理方法进行处理

 public void fnProcessDirectory(string strPath)
    {
        if (File.Exists(strPath))
        {
            fnProcessFile(strPath);
        }
        else if (Directory.Exists(strPath))
        {
            string[] fileEntries = Directory.GetFiles(strPath);
            string[] subdirEntries = Directory.GetDirectories(strPath);

            foreach (string fileName in fileEntries)
            {
                fnProcessFile(fileName);
            }

            foreach (string dirName in subdirEntries)
            {
                fnProcessDirectory(dirName);
            }
        }
    }

    public void fnProcessFile(string strPath)
    {
        //ProcessFile
    }
