hi,

try this code....

Dim Action As New ShellActions
Action.EmptyRecycleBin()

Public Class ShellActions

Shared Function _
SHEmptyRecycleBin(ByVal hWnd As Integer, ByVal pszRootPath As String, _
ByVal dwFlags As Integer) As Integer
End Function

Sub New()
EmptyRecycleBin()
End Sub

Sub EmptyRecycleBin(Optional ByVal rootPath As String = "", _
Optional ByVal noConfirmation As Boolean = True, Optional ByVal NoProgress _
As Boolean = True, Optional ByVal NoSound As Boolean = True)

Const SHERB_NOCONFIRMATION = &H1
Const SHERB_NOPROGRESSUI = &H2
Const SHERB_NOSOUND = &H4

If rootPath.Length > 0 AndAlso rootPath.Substring(1, 2) <> ":\" Then
rootPath = rootPath.Substring(0, 1) & ":\"
End If

Dim flags As Integer = (noConfirmation And SHERB_NOCONFIRMATION) Or _
(NoProgress And SHERB_NOPROGRESSUI) Or (NoSound And SHERB_NOSOUND)
SHEmptyRecycleBin(0, rootPath, flags)

End Sub

Hi,

We can clear the RecycleBin simply by using the Shell32.dll in C#.

Just import the dll using System.Runtime.InteropServices call the function SHEmptyRecycleBin .

shell32.dll is a library which contains Windows Shell API functions, which are used when opening web pages and files.

Here is sample code …

Code:

enum RecycleFlags : uint
        {
            SHERB_NOCONFIRMATION = 0x00000001,
            SHERB_NOPROGRESSUI = 0x00000002,
            SHERB_NOSOUND = 0x00000004
        }

[DllImport("Shell32.dll",CharSet=CharSet.Unicode)]
        static extern uint SHEmptyRecycleBin(IntPtr hwnd, string pszRootPath, RecycleFlags dwFlags);

Code:

try
 {
   uint result = SHEmptyRecycleBin(IntPtr.Zero, null, 0);
   MessageBox.Show(this,"Done !","Empty the 
          RecycleBin",MessageBoxButtons.OK,MessageBoxIcon.Information);
 }
catch(Exception ex)
  {
    MessageBox.Show(this, "Failed ! " + ex.Message, "Empty the 
RecycleBin", MessageBoxButtons.OK, MessageBoxIcon.Stop);
    Application.Exit();
  }
