J＃集合到VB .NET集合

Question

我有一系列返回J＃数据类型的API调用。我已经能够很好地转换大多数数据类型（Integer，Boolean，Double，Float等）。

我现在需要做的是将java.Util.Collection转换为VB .NET集合（ArrayList？）

这是我的尝试：

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

我不断收到运行时错误“无法将'AbstractListlistIterator'类型的对象强制转换为'System.Collections.IEnumerator。有什么想法？

未经测试，但应该有效：

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
