vb.net - 如何以编程方式添加/删除引用？

Question

我的应用程序是为在 VB.NET 中扫描 MS Access 数据库而构建的。

当 Access 应用程序分发给最终用户时，他们可能拥有不同版本的 COM 组件。是否可以通过编程方式添加/删除引用来解决由于版本不同而损坏的引用？

请分享我的代码或链接以供引用。

下面是一些示例代码:

从文件创建引用

  Sub AddWS()
  'Create a reference to Windows Script Host, '
  'where you will find FileSystemObject ' 
  'Reference name: "IWshRuntimeLibrary" '
  'Reference Name in references list: "Windows Script Host Object Model" '
  ReferenceFromFile "C:\WINDOWS\System32\wshom.ocx"
  End Sub

  Function ReferenceFromFile(strFileName As String) As Boolean
  Dim ref As Reference

         On Error GoTo Error_ReferenceFromFile
         References.AddFromFile (strFileName)
         ReferenceFromFile = True

  Exit_ReferenceFromFile:
         Exit Function

   Error_ReferenceFromFile:
         ReferenceFromFile = False
         Resume Exit_ReferenceFromFile
   End Function 

删除引用

  Sub DeleteRef(RefName)
  Dim ref As Reference

      'You need a reference to remove '
      Set ref = References(RefName)
      References.Remove ref

  End Sub 


You can use the references collection to find if a reference exists.

引用文献存在

  Function RefExists(RefName)
  Dim ref As Object

     RefExists = False

     For Each ref In References
         If ref.Name = RefName Then
             RefExists = True
         End If
     Next

  End Function
