Question

我可以使用BETALIB阅读器读取文件夹文件，但是通过在folderbrowserdialog中给出路径一个来阅读它我可以读取文件夹，但在该文件夹中有许多文件夹和文件，我想阅读子文件夹。

表示： - E：\ EXE \ TTD \ ttd1 \ ttd2 \ BSEM \ f1.dat E：\ EXE \ TTD \ ttd1 \ ttd2 \ MCDEX \ f1.dat

我想通过在folderbrowserdialog中给出路径来读取文件 EX：E：\ EXE

如果我选择路径E：\ EXE，它应该读取包含在其中的所有子文件夹和文件。

任何人都可以说我应该在代码中更改

    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
            {

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

1）在处理目录上创建两个函数，在处理文件上创建一个函数 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，则递归调用自身 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
    }
