J# collection to VB .NET collection

문제
I have a series of API calls that are returning J# data types. I have been able to convert most of the data types (Integer, Boolean, Double, Float, etc) just fine.
What I need to do now is convert a java.Util.Collection to a VB .NET collection (ArrayList?)
Here is my attempt:
Public Function MakeDotNETCollection(ByVal javaCol As java.util.Collection) As Collection
Dim dotNetCol As Collection
If Not javaCol Is Nothing Then
dotNetCol = New Collection
Dim it As IEnumerator = javaCol.iterator()
For Each it In CType(javaCol, Collection)
dotNetCol.Add(it.Current)
Next it
End If
Return dotNetCol
End Function
I keep getting a runtime error "Unable to cast object of type 'AbstractListlistIterator' to type 'System.Collections.IEnumerator. Any ideas?
해결책
Not tested, but should work:
Public Function MakeDotNETCollection(ByVal javaCol As java.util.Collection) As Collection
Dim dotNetCol As Collection
If Not javaCol Is Nothing Then
dotNetCol = New Collection
Dim it As java.util.Iterator = javaCol.iterator()
While it.HasNext()
dotNetCol.Add(it.next())
End While
End If
Return dotNetCol
End Function
