<p>Programmatic solution of course...</p>

You need to delve into unmanaged code. Here's a static class that I've been using:
```
```
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 + '\0' + '\0';
        fileop.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;

        SHFileOperation(ref fileop);
    }
}
```
```
Addendum:
Tsk tsk @ Jeff for "using Microsoft.VisualBasic" in C# code.
Tsk tsk @ MS for putting all the goodies in VisualBasic namespace.
