문제
현재 다음 기능을 사용하고 있습니다
file.Delete();
하지만 이 기능을 사용하여 파일을 완전히 삭제하는 대신 휴지통으로 보낼 수 있는 방법은 무엇입니까?
해결책
참고 : Windows 서비스와 같은 비 UI 대화식 앱에서도 작동하지 않습니다
이 래퍼는 필요한 기능을 제공 할 수 있습니다.

. 다른 팁
filesystem.deletefile 올바른 RecycleOption . UI 대화식 앱에서 작동하지만 Windows 서비스 응용 프로그램과 같은 비 UI 대화식 앱에서는 작동하지 않습니다.
다음 해결책은 다른 것보다 간단합니다.
using Shell32;
static class Program
{
public static Shell shell = new Shell();
public static Folder RecyclingBin = shell.NameSpace(10);
static void Main()
{
RecyclingBin.MoveHere("PATH TO FILE/FOLDER")
}
}
.
이 라이브러리를 사용하여 휴지통의 다른 기능을 사용할 수 있습니다.
먼저 Shell32
네임 스페이스를 사용할 수 있도록 "Microsoft Shell 컨트롤 및 자동화"(COM 메뉴) 라이브러리를 추가하는 것을 잊지 마십시오.프로그램과 함께 컴파일되는 대신 프로젝트에 동적으로 연결됩니다.
안타깝게도 파일을 휴지통으로 제거하려면 Win32 API를 사용해야 합니다.다음 코드를 기반으로 시도해 보세요. 이 게시물.일반을 사용합니다. SHFileOperation
Windows Shell을 통한 파일 시스템 작업을 위한 기능입니다.
다음을 정의합니다(유틸리티 클래스가 가장 좋습니다).
[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;
}
[DllImport("shell32.dll", CharSet=CharSet.Auto)]
public static extern int SHFileOperation(ref SHFILEOPSTRUCT FileOp);
public const int FO_DELETE = 3;
public const int FOF_ALLOWUNDO = 0x40;
public const int FOF_NOCONFIRMATION = 0x10; // Don't prompt the user
그리고 이를 사용하여 파일을 삭제하고 휴지통으로 보내려면 다음과 같은 것이 필요합니다.
var shf = new SHFILEOPSTRUCT();
shf.wFunc = FO_DELETE;
shf.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;
shf.pFrom = @"C:\test.txt";
SHFileOperation(ref shf);

첫 번째 참조 Microsoft.VisualBasic 그런 다음이 코드를 추가하십시오 :
FileSystem.DeleteFile(path_of_the_file,
Microsoft.VisualBasic.FileIO.UIOption.AllDialogs,
Microsoft.VisualBasic.FileIO.RecycleOption.SendToRecycleBin,
Microsoft.VisualBasic.FileIO.UICancelOption.ThrowException);

이 확장 방법을 사용하고 DirectoryInfo 또는 FileInfo를 사용하고 삭제할 수 있습니다.

var rc= SHFileOperation(ref fileop);
return rc==0;
}
public static bool ToRecycleBin(this DirectoryInfo dir)
{
dir?.Refresh();
if(dir is null || !dir.Exists)
{
return false;

샘플을 호출하는 방법은 다음과 같을 수 있습니다.
private void BtnDelete_Click(object sender, EventArgs e)
{
if(MessageBox.Show("Are you sure you would like to delete this directory?", "Delete & Close", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
return;
var dir= new DirectoryInfo(directoryName);
dir.ToRecycleBin();
}
