convert c#'~' to vb.net

I find this c# and I want to translate it into vb.net code but I could. I found inside msdn it says it is an OnesComplement. I post the code in c# and if any one know hor to convert this to vb.net code please help me.

~TwCapability()
{
if( Handle != IntPtr.Zero )
Twain.GlobalFree( Handle );
}

Thanks

When I uset the translator Here i got the following, could that be right ?

Code:

---

Overrides Sub Finalize()
  If Handle <> IntPtr.Zero Then
      Twain.GlobalFree(Handle)
  End If
  MyBase.Finalize()
End Sub

---

Yes thats right. The tilde (~) is used for a destructor function in a class. In VB.NET you have to override the Finalize function to implement your own destructor.

Its right, it is a destructor. We should use
finalise() or TwCapability()?

Anyway Thanks guys by helping me.
