Module Example
Public Sub Main()
Dim mc1 As New ManagedClass()
Dim mc2 As New ManagedClass()
Dim mc3 As New ManagedClass()
Dim cwt As New ConditionalWeakTable(Of ManagedClass, ClassData)()
cwt.Add(mc1, New ClassData())
cwt.Add(mc2, New ClassData())
cwt.Add(mc3, New ClassData())
Dim wr2 As New WeakReference(mc2)
mc2 = Nothing
GC.Collect()
Dim data As ClassData = Nothing
If wr2.Target Is Nothing Then
Console.WriteLine("No strong reference to mc2 exists.")
Else If cwt.TryGetValue(mc2, data) Then
Console.WriteLine("Data created at {0}", data.CreationTime)
Else
Console.WriteLine("mc2 not found in the table.")
End If
End Sub
End Module
