我需要基于一些表创建一个 Excel 应用程序。

我在 VBA 中运行了代码，它工作正常。在“Visual Studio”中它不起作用。

我的代码在这里：

Dim xlApp As Excel.Application
xlApp = Globals.ThisAddIn.Application
xlApp.ActiveWorkbook.Connections.Add2("Target Connection Name", "", _
     "OLEDB;Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Data Source=SERVER\SQLEXPRESS;Use Procedure for Prepare=1;Auto Translate=True;Packet 
      Size=8192;Workstation ID=NAME;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=MYSQLDATABASE;", _
      """TAB_CATEGORIA"",""TAB_MOVIMENTO""", Excel.XlCmdType.xlCmdTableCollection, vbTrue, vbTrue)

当我执行此代码时，我收到以下消息：

“找不到磁带目录。使用 Windows Installer 修复应用程序。”

我意识到当我们生成一个新实例时，它可以工作：

Dim xlApp As NEW Excel.Application

但是，不幸的是，我需要当前实例

xlApp = Globals.ThisAddIn.Application

当我使用“Globals.ThisAddIn.Application”生成 WorkbookConnection 对象时，抛出异常。

看起来不兼容，认为office 2016是一个单线程应用程序。它使 Add2 命令被 Excel UI 阻止
