Question

制作一个包含大量功能的文件浏览器，回过头来调整我的一些方法来找到它：

foreach (ListViewItem item in listView1.SelectedItems)
{
    FileSystem.DeleteDirectory(item.SubItems[3].Text,  
        UIOption.AllDialogs,
        RecycleOption.SendToRecycleBin,
        UICancelOption.ThrowException);
}

非常适合将SINGLE目录或文件发送到回收站，但它会提示每个选定的项目。不适合删除一堆文件和文件夹。

在没有多余提示的情况下实现这一目标的任何方法？或者我是否必须深入研究SHFILEOPSTRUCT？

感谢您的帮助，到目前为止，我的问题中有90％已经在这里得到了答案，这是最好的网站。

Answer 1

如果您不想要提示，可以使用Directory.Delete代替FileSystem方法。这将删除目录以及文件和子目录（前提是您指定要执行此操作）。

Answer 2

这似乎是做你所需要的唯一方法将文件和目录无提示地移动到回收站

using System.Runtime.InteropServices;

class Win32ApiUtils
{
    // Don't declare a value for the Pack size. If you omit it, the correct value is used when  
    // marshaling and a single SHFILEOPSTRUCT can be used for both 32-bit and 64-bit operation.
    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
    public struct SHFILEOPSTRUCT
    {
        public IntPtr hwnd;
        [MarshalAs(UnmanagedType.U4)]
        public int wFunc;
        [MarshalAs(UnmanagedType.LPWStr)]
        public string pFrom;
        [MarshalAs(UnmanagedType.LPWStr)]
        public string pTo;            
        public ushort fFlags;
        [MarshalAs(UnmanagedType.Bool)]
        public bool fAnyOperationsAborted;
        public IntPtr hNameMappings;
        [MarshalAs(UnmanagedType.LPWStr)]
        public string lpszProgressTitle;
   }

   [DllImport("shell32.dll", CharSet = CharSet.Auto)]
   static extern int SHFileOperation(ref SHFILEOPSTRUCT FileOp);
   const int FO_DELETE = 3;
   const int FOF_ALLOWUNDO = 0x40;
   const int FOF_NOCONFIRMATION = 0x10; //Don't prompt the user.; 

   public static int DeleteFilesToRecycleBin(string filename)
   {
        SHFILEOPSTRUCT shf = new SHFILEOPSTRUCT();
        shf.wFunc = FO_DELETE;
        shf.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;
        shf.pFrom = filename + "\0";  // <--- this "\0" is critical !!!!!
        int result = SHFileOperation(ref shf);
        // Any value different from zero is an error to lookup 
        return result;

   }

}

   foreach (ListViewItem item in listView1.SelectedItems)
   {
        int result = Win32ApiUtils.DeleteFilesToRecycleBin(item.SubItems[3].Text);
        if(result != 0) ...... // ??? throw ??? message to user and contine ???
   }

- 警告 - 此代码需要进行测试。我在PInvoke site上找到了SHFILEOPSTRUCT的布局，在该链接上有一些关于所用字符串声明的注释。

好。在我的Win7 64bit上测试了一个目录要删除。像魅力一样......

使用FileSystem.DeleteDirectory将多个目录发送到回收站
