Vba 如何将日期添加到附件名称？

我的VBA代码将附件从电子邮件下载到本地驱动器。我想重命名附件以包含日期。日期应为收到电子邮件的前一天

Public Sub SaveAutoAttach(item As Outlook.MailItem)

Dim object_attachment As Outlook.Attachment

Dim saveFolder As String
' Folder location when I want to save my file
saveFolder = "\\gbhxxxx\Groups\Shared\EBS\Post Go-Live\Auto MT940 download Test"

For Each object_attachment In item.Attachments

    ' Criteria to save .940 files only
    If InStr(object_attachment.DisplayName, "UKAutoMT940") Then
        object_attachment.SaveAsFile saveFolder & "\" & object_attachment.DisplayName
    End If

Next

End Sub

---

更新了下面的代码，将日期附加到显示文件名之前。为此，我们使用DATEADD并向接收日期添加-1天，并将datetime值格式化为带有“-”s而不是“/”s的日期值

如果您希望在文件名之后但在扩展名之前添加它，我们需要解析为文件名

Public Sub SaveAutoAttach(item As Outlook.MailItem)

Dim object_attachment As Outlook.Attachment

Dim saveFolder As String
' Folder location when I want to save my file
saveFolder = "\\gbhxxxx\Groups\Shared\EBS\Post Go-Live\Auto MT940 download Test"


    For Each object_attachment In item.Attachments
' Criteria to save .940 files only

    If InStr(object_attachment.DisplayName, "UKAutoMT940") Then

       object_attachment.SaveAsFile saveFolder & "\" & Format(DateAdd("d", -1, item.ReceivedTime), "dd-mm-yyyy") & "_" & object_attachment.DisplayName
    End If

    Next

End Sub
