Ms access 如何在VBA中创建词典集合？

我正试图用VBA建立一个字典集。构建集合后，它将转换为JSON，并以HTTP请求的形式发送到web服务

因为字典是对象，所以它们是通过引用而不是通过值添加到集合中的。结果是，我的收藏由相同的词典组成，而不是我想要的单个词典

Dim qdf As DAO.QueryDef
Dim rs As DAO.Recordset

Set qdf = CurrentDb.QueryDefs("qryTutors")
Set rs = qdf.OpenRecordset

Dim tutors As New Collection

If Not (rs.EOF And rs.BOF) Then
    Do Until rs.EOF = True
        Dim tutor As New Scripting.Dictionary
        tutor.Add "TutorName", rs!TutorFirstName.Value & " " & rs!TutorSurname.Value
        tutor.Add "TutorEmail", rs!TutorEmail.Value
        tutor.Add "TutorSubject", rs!TutorSubject.Value
        tutors.Add tutor
        tutor.RemoveAll
        rs.MoveNext
    Loop
End If

txtOutput.Value = JsonConverter.ConvertToJson(tutors)

rs.Close 'Close the recordset
Set rs = Nothing 'Clean up

---

感谢您的帮助。

在每次迭代中使用新词典：

Dim qdf As DAO.QueryDef
Dim rs As DAO.Recordset

Set qdf = CurrentDb.QueryDefs("qryTutors")
Set rs = qdf.OpenRecordset

Dim tutors As New Collection
Dim tutor As Scripting.Dictionary

If Not (rs.EOF And rs.BOF) Then
    Do Until rs.EOF = True
        Set tutor = New Scripting.Dictionary
        tutor.Add "TutorName", rs!TutorFirstName.Value & " " & rs!TutorSurname.Value
        tutor.Add "TutorEmail", rs!TutorEmail.Value
        tutor.Add "TutorSubject", rs!TutorSubject.Value
        tutors.Add tutor
        rs.MoveNext
    Loop
End If

txtOutput.Value = JsonConverter.ConvertToJson(tutors)

rs.Close 'Close the recordset
Set rs = Nothing 'Clean up
