如何使用 Microsoft Word API 和书签功能以编程方式将 Word 文档打开到特定位置？

我正在 Windows 窗体应用程序中尝试以下代码。我不确定我做错了什么（而且我很容易做错，因为我对 Word API 没有太多经验），但 GoTo 命令就是找不到书签。我总是在最后一行收到 COMException“此书签不存在”。

But the wordDoc.Bookmarks.get_Item(ref name)方法确实找到了书签！是什么赋予了？

Object fileName = System.Windows.Forms.Application.StartupPath + "\\Bookmarks.docx";
Object readOnly = false;
Object isVisible = true;
Object missing = System.Reflection.Missing.Value;

Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application();
Microsoft.Office.Interop.Word.Document wordDoc = new Microsoft.Office.Interop.Word.Document();

wordApp.Visible = true;
wordDoc = wordApp.Documents.Open(ref fileName, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible, ref missing, ref missing, ref missing, ref missing);

Object item = Microsoft.Office.Interop.Word.WdGoToItem.wdGoToBookmark;
Object whichitem = Microsoft.Office.Interop.Word.WdGoToDirection.wdGoToFirst;
Object count = 1;
Object name = "Location3";

Bookmark bMark = wordDoc.Bookmarks.get_Item(ref name);
wordDoc.GoTo(ref item, ref whichitem, ref count, ref name);

使用 Bookmark 对象怎么样？

    object bookmarkName = "Location3";
    if (wordDoc.Bookmarks.Exists(bookmarkName.ToString()))
    {
        Bookmark bookmark = wordDoc.Bookmarks.get_Item(ref bookmarkName);
        bookmark.Select();
    }

我没有检查窗口是否滚动到那里...但这应该可以帮助您开始。

EDIT：这是我执行 Goto->Bookmark 宏时记录的 VB 代码：

Selection.GoTo What:=wdGoToBookmark, Name:="Location3"

您是否尝试为 WhichItem 和 Count 传递 Type.Missing 以便它复制 VB 调用？
