在Outlook中编写邮件时，如何将所有附件名称列出到邮件正文中？

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
    Dim xMailItem As MailItem
    If Item.Class = olMail Then
        Set xMailItem = Item
        If xMailItem.Attachments.Count > 0 Then
          AddAttachmentNamesToBody
        End If
    End If
    End Sub

Public Sub AddAttachmentNamesToBody()
    Dim xMailItem As MailItem
    Dim xAttachment As Attachment
    Dim xFileName As String
   Dim xInspector As Outlook.Inspector
    Dim xDoc As Word.Document
    Dim xWdSelection As Word.Selection
    On Error Resume Next
    Set xMailItem = Outlook.ActiveInspector.CurrentItem
    If xMailItem.Attachments.Count = 0 Then
        Exit Sub
    End If
    xFileName = ""
    For Each xAttachment In xMailItem.Attachments
        If xFileName = "" Then
            xFileName = " <" & xAttachment.FileName & "> "
        Else
            xFileName = xFileName & vbCrLf & " <" & xAttachment.FileName & "> "
        End If
    Next xAttachment
    Set xInspector = Outlook.Application.ActiveInspector()
    Set xDoc = xInspector.WordEditor
    Set xWdSelection = xDoc.Application.Selection
    xWdSelection.HomeKey Unit:=wdStory
    xWdSelection.InsertBefore "Attachments: " & vbCrLf & xFileName & vbCrLf & vbCrLf
    Set xMailItem = Nothing
    End Sub
