我正在使用.NET Compact Framework的3.5和想要删除某些特定文件夹及其子文件夹。当我运行应用程序，它给 IO异常 。我试着使用 Directory.Delete（路径） 方法，但没有奏效。

我该如何解决这个问题呢？

下面是我的code：

 使用系统;
使用System.Diagnostics程序;
使用System.IO;
使用System.Linq的;
使用System.Collections.Generic;
使用System.Windows.Forms的;

命名空间Reset_Client
{
  静态类节目
  {
      静态无效的主要（）{
         MYFUNC（）;
         的MessageBox.show（Cihaz resetlendi！）;
      }

      公共静态无效MYFUNC（）
      {
          字符串主路径= @\存储卡\ deneme;

          尝试
          {
              DeleteDirectory（MainPath的+CRM）;
              DeleteDirectory（MainPath的+BHTS）;
              DeleteDirectory（主路径+图像）;
              DeleteDirectory（主路径+风）;
              DeleteDirectory（主路径+表）;
              DeleteDirectory（主路径+日志）;

              File.Delete（MainPath的+Agentry.ini）;
              File.Delete（MainPath的+Agentry.app）;
              File.Delete（MainPath的+Agentry.usr）;
          }
          赶上（IOException异常E）
          {
              MYFUNC（）;
          }
      }

      公共静态无效DeleteDirectory（字符串TARGET_DIR）
      {
          FileInfo的的fileInfo =新的FileInfo（TARGET_DIR）;
          FileAttributes属性= fileInfo.Attributes;

          如果（（属性和放大器; FileAttributes.ReadOnly）== FileAttributes.ReadOnly）
          {
              //设置属性nonreadonly
              fileInfo.Attributes和放大器; =〜FileAttributes.ReadOnly;
          }

          字符串[]文件= Directory.GetFiles（TARGET_DIR）;
          字符串[]迪尔斯= Directory.GetDirectories（TARGET_DIR）;

          的foreach（在文件中字符串的文件）
          {
              File.Delete（文件）;
          }

          的foreach（在显示目录字符串DIR）
          {
              DeleteDirectory（DIR）;
          }

          Directory.Delete（TARGET_DIR，假）;
      }
   }
}
 

解决方案

为什么不删除目录递归：

  Directory.Delete（路径，真实）;
 

请参阅这里。

此外，请参阅here因为它可能是类似于您遇到。

I'm working with the .NET Compact Framework 3.5 and want to delete some specific folders and their subfolders. When I run the app it gives IO exception. I've tried to use Directory.Delete(path) method but it didn't work.

How can I solve this problem?

Here is my code :

using System;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Collections.Generic;
using System.Windows.Forms;

namespace Reset_Client
{
  static class Program
  {
      static void Main(){
         myfunc();
         MessageBox.Show("Cihaz resetlendi!");
      }

      public static void myfunc()
      {
          string mainPath = @"\Storage Card\deneme";

          try
          {
              DeleteDirectory(mainPath + "CRM");
              DeleteDirectory(mainPath + "BHTS");
              DeleteDirectory(mainPath + "IMAGES");
              DeleteDirectory(mainPath + "STYLES");
              DeleteDirectory(mainPath + "TABLES");
              DeleteDirectory(mainPath + "LOG");

              File.Delete(mainPath + "Agentry.ini");
              File.Delete(mainPath + "Agentry.app");
              File.Delete(mainPath + "Agentry.usr");
          }
          catch (IOException e)
          {
              myfunc();
          }
      }

      public static void DeleteDirectory(string target_dir)
      {
          FileInfo fileInfo = new FileInfo(target_dir);
          FileAttributes attributes = fileInfo.Attributes;

          if ((attributes & FileAttributes.ReadOnly) == FileAttributes.ReadOnly)
          {
              // set the attributes to nonreadonly
              fileInfo.Attributes &= ~FileAttributes.ReadOnly;
          }

          string[] files = Directory.GetFiles(target_dir);
          string[] dirs = Directory.GetDirectories(target_dir);

          foreach (string file in files)
          {
              File.Delete(file);
          }

          foreach (string dir in dirs)
          {
              DeleteDirectory(dir);
          }

          Directory.Delete(target_dir, false);
      }
   }
}

Why not delete the directory recursively:

Directory.Delete(path, true);
