Following Code sample requires one Button control named ‘btnRecycleBin’ on windows form.
using System; using System.Windows.Forms; using System.Runtime.InteropServices; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } enum RecycleFlags : uint { SHRB_NOCONFIRMATION = 0x00000001, SHRB_NOPROGRESSUI = 0x00000002, SHRB_NOSOUND = 0x00000004 } [DllImport("Shell32.dll", CharSet = CharSet.Unicode)] static extern uint SHEmptyRecycleBin(IntPtr hwnd, string pszRootPath, RecycleFlags dwFlags); private void btnRecycleBin_Click(object sender, EventArgs e) { DialogResult result; result = MessageBox.Show("Are you sure to delete all items in recycle bin", "Empty Recycle bin", MessageBoxButtons.YesNo); if (result == DialogResult.Yes) { try { uint IsSuccess = SHEmptyRecycleBin(IntPtr.Zero, null, RecycleFlags.SHRB_NOCONFIRMATION); MessageBox.Show("Empty the RecycleBin successsfully", "Empty the RecycleBin", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch (Exception ex) { MessageBox.Show("Empty the RecycleBin failed" + ex.Message, "Empty the RecycleBin", MessageBoxButtons.OK, MessageBoxIcon.Stop); Application.Exit(); } } } } }
