J＃收集到VB .NET收集

Question

我有一系列返回J＃数据类型的API调用。我已经能够转换大多数数据类型（整数，布尔值，双，浮点等）。

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

我一直在遇到一个运行时错误“无法将'AbstractListListIterator'类型的对象施加到type'System.Collections.ienumerator。有什么想法吗？

未经测试，但应该起作用：

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
