Recycle Bin

Funny you should ask (months ago apparently) - because I just solved this problem. Here's a very stripped-down example. This is just a wrapper around SHFileOperation - no constants - just literals. It will delete a file (wFunc=3) silently (fFlags=4) allow undelete / move to recycle bin (fFlags=64) with no confirmation (fFlags=16). using System; using Microsoft.Win32; using System.Runtime.InteropServices; using System.IO; namespace Shell { public class Recycle { [DllImport("shell32.dll")] private static extern Int32 SHFileOperation(ref SHFILEOPSTRUCT FileOp); [StructLayout(LayoutKind.Sequential)] public struct SHFILEOPSTRUCT { public IntPtr hWnd; public Int32 wFunc; [MarshalAs(UnmanagedType.LPStr)] public String pFrom; [MarshalAs(UnmanagedType.LPStr)] public String pTo; public Int32 fFlags; public Int32 fAnyOperationsAborted; public IntPtr hNameMappings; [MarshalAs(UnmanagedType.LPStr)] public System.String lpszProgressTitle; } public static bool Delete(string pstrFile) { Int32 intRet; SHFILEOPSTRUCT objSHFileOperationStruct = new SHFILEOPSTRUCT(); try { objSHFileOperationStruct.wFunc = 3; //delete file objSHFileOperationStruct.fFlags = 84; //allow-undo + no-confirmation + silent objSHFileOperationStruct.pFrom = pstrFile; intRet = SHFileOperation(ref objSHFileOperationStruct); if (objSHFileOperationStruct.fAnyOperationsAborted != 0 || intRet != 0) { return false; } else { return true; } } catch { return false; } } } }
