如何将 C# Object Cast 转换为 VB.net Object Cast？（显示了特定的 Cast 方法）

Question

我正在努力将下面的代码转换为 VB.Net。我在这里做错了什么？

代码：这是我在下面尝试的。我尝试转换以下语句：

(gotoAction.Destination, PDFPageDirectDestination).Page = destinationPage
            bookmark.Action = gotoAction

在下面的函数中声明这个：（我用的是DirectCast）

 Public Shared Function CreateBookmark(title As String, bookmarkColor As PDFRgbColor, visualStyle As PDFOutlineItemVisualStyle, destinationPage As PDFPage) As PDFOutlineItem

           
            Dim bookmark As PDFOutlineItem = New PDFOutlineItem()
            bookmark.Title = title
            bookmark.Color = bookmarkColor
           
            bookmark.VisualStyle = visualStyle

            Dim gotoAction As PDFGoToAction = New PDFGoToAction()
            
            gotoAction.Destination = New PDFPageDirectDestination()
            
            DirectCast(gotoAction.Destination, PDFPageDirectDestination).Page = destinationPage
            bookmark.Action = gotoAction

            Return bookmark
        End Function

试试这个，不需要转换：

Public Shared Function CreateBookmark(title As String, bookmarkColor As PDFRgbColor, visualStyle As PDFOutlineItemVisualStyle, destinationPage As PDFPage) As PDFOutlineItem          
     Dim bookmark As New PDFOutlineItem()
     bookmark.Title = title
     bookmark.Color = bookmarkColor          
     bookmark.VisualStyle = visualStyle

     Dim gotoAction As New PDFGoToAction()   
     Dim destination As New PDFPageDirectDestination()                   
     destination.Page = destinationPage
     gotoAction.Destination = destination
     bookmark.Action = gotoAction

     Return bookmark
End Function
