How do you place a file in recycle bin instead of delete?
提问by Brian Leahy
Programmatic solution of course...

From above:
从上面：
using Microsoft.VisualBasic;
string path = @"c:\myfile.txt";
FileIO.FileSystem.DeleteDirectory(path,
FileIO.UIOption.OnlyErrorDialogs,
RecycleOption.SendToRecycleBin);

You need to delve into unmanaged code. Here's a static class that I've been using:
您需要深入研究非托管代码。这是我一直在使用的静态类：
public static class Recycle
{
private const int FO_DELETE = 3;
private const int FOF_ALLOWUNDO = 0x40;
private const int FOF_NOCONFIRMATION = 0x0010;
[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)]
static extern int SHFileOperation(ref SHFILEOPSTRUCT FileOp);
public static void DeleteFileOperation(string filePath)
{
SHFILEOPSTRUCT fileop = new SHFILEOPSTRUCT();
fileop.wFunc = FO_DELETE;
fileop.pFrom = filePath + 'Microsoft.VisualBasic.FileIO.FileSystem.DeleteFile(file.FullName,
Microsoft.VisualBasic.FileIO.UIOption.OnlyErrorDialogs,
Microsoft.VisualBasic.FileIO.RecycleOption.SendToRecycleBin);
' + '##代码##';
fileop.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;
SHFileOperation(ref fileop);
}
}
Addendum:
附录：
- Tsk tsk @ Jeff for "using Microsoft.VisualBasic" in C# code.
- Tsk tsk @ MS for putting all the goodies in VisualBasic namespace.
- Tsk tsk @ Jeff 在 C# 代码中“使用 Microsoft.VisualBasic”。
- Tsk tsk @ MS 将所有好东西都放在 VisualBasic 命名空间中。

The best way I have found is to use the VB function FileSystem.DeleteFile.
我发现的最好方法是使用 VB 函数FileSystem.DeleteFile。
It requires adding Microsoft.VisualBasicas a reference, but this is part of the .NET framework and so isn't an extra dependency.
它需要添加Microsoft.VisualBasic作为参考，但这是 .NET 框架的一部分，因此不是额外的依赖项。
Alternate solutions require a P/Invoke to SHFileOperation, as well as defining all the various structures/constants. Including Microsoft.VisualBasicis much neater by comparison.
替代解决方案需要 P/Invoke 到SHFileOperation，以及定义所有各种结构/常量。Microsoft.VisualBasic相比之下，包括更整洁。
