如何读取包含在其中的子文件夹和文件

Question

我可以通过使用BETALIB阅读器读取文件夹文件，但它通过在folderbrowserdialog中给出路径来读取大文件夹 我可以读取文件夹，但在该文件夹中有很多我想要读取子文件夹的文件夹和文件。

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

我想读通过给文件夹浏览器对话框中的路径 EX：E：\ EXE

如果我选择路径E：\ EXE它应该读取其中包含的所有子文件夹和文件。

任何一个可以说我什么，我应该在代码

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 
      { 

      } 


     } 
    }

可以使用System.IO类库的DirectoryInfo和FileInfo类和逻辑去如下

1）到进程目录创建两个函数，一个用于处理文件 2）在该目录中读取功能读取验证如果该项目是文件或目录 3）如果产品目录它递归调用自身 4）如果项目是文件，它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 
    }
