C#實現(xiàn)刪除文件和目錄到回收站

這篇文章主要為大家詳細(xì)介紹了如何使用C#實現(xiàn)刪除文件和目錄到回收站,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下

之前在c++上遇到過這個問題，折騰許久才解決了，這次在c#上再次遇到這個問題，不過似乎容易了一些，親測代碼如下，兩種刪除方式都寫在代碼中了。

直接上完整代碼：

using Microsoft.VisualBasic.FileIO;
using System;
using System.IO;
using System.Runtime.InteropServices;
 
namespace ceshiConsole
{
    public class FileIOHelper
    {
        [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto, Pack = 1)]
        public struct SHFILEOPSTRUCT
        {
            public IntPtr hwnd;
            [MarshalAs(UnmanagedType.U4)]
            public int wFunc;
            public string pFrom;
            public string pTo;
            public short fFlags;
            [MarshalAs(UnmanagedType.Bool)]
            public bool fAnyOperationsAborted;
            public IntPtr hNameMappings;
            public string lpszProgressTitle;
        }
 
        #region Dllimport
        [DllImport("shell32.dll", CharSet = CharSet.Auto)]
        public static extern int SHFileOperation(ref SHFILEOPSTRUCT FileOp);
        #endregion
        #region Const
        public const int FO_DELETE = 3;
        public const int FOF_ALLOWUNDO = 0x40;
        public const int FOF_NOCONFIRMATION = 0x10;
        #endregion
 
        #region Public Static Method
        public static void DeleteFileToRecyclebin(string file, Boolean showConfirmDialog = false)
        {
            SHFILEOPSTRUCT shf = new SHFILEOPSTRUCT();
            shf.wFunc = FO_DELETE;
            shf.fFlags = FOF_ALLOWUNDO;
            if (!showConfirmDialog)
            {
                shf.fFlags |= FOF_NOCONFIRMATION;
            }
            shf.pFrom = file + '\0' + '\0';
            SHFileOperation(ref shf);
        }
 
        public static bool SendToRecycleBin(string path)
        {
            bool bRet = true;
            try
            {
                if (File.Exists(path))
                {
                    FileSystem.DeleteFile(path, UIOption.OnlyErrorDialogs, RecycleOption.SendToRecycleBin);
                }
                else if (Directory.Exists(path))
                {
                    FileSystem.DeleteDirectory(path, UIOption.OnlyErrorDialogs, RecycleOption.SendToRecycleBin);
                }
                else
                {
                    bRet = false;
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"無法將文件/目錄 {path} 移動到回收站: {ex.Message}");
                bRet = false;
            }
 
            return bRet;
        }
 
        static void Main(string[] args)
        {
            DeleteFileToRecyclebin(@"C:\Users\autumoon\Desktop\test.txt");
            SendToRecycleBin(@"C:\Users\autumoon\Desktop\test2.txt");
        }
 
        #endregion
    }
}
