背景: 在C#中的PowerPoint幻灯片中,有一个属性Slide.Name(通常包含任意字符串值)。我想在我的C#应用程序中使用此属性来标识幻灯片(幻灯片顺序不可靠)。
问题: 如何手动设置PowerPoint应用程序中的Slide.Name属性?
我的问题非常类似于“如何在PowerPoint幻灯片内命名对象?”,但仅适用于幻灯片级别。
任何帮助将不胜感激。

在PowerPoint中,没有内置的功能可以编辑幻灯片的名称。正如Steve所提到的,您必须使用VBA代码进行操作。插入更多幻灯片不会更改幻灯片名称;即使关闭了PowerPoint,幻灯片名称设置在VBA代码中也是持久的。下面是我编写的一些代码,可以让您轻松查看当前选定幻灯片的名称并将其重命名:
'------------------------------------------------------------------
' NameSlide()
'
' Renames the current slide so you can refer to this slide in
' VBA by name. This is not used as part of the application;
' it is for maintenance and for use only by developers of
' the PowerPoint presentation.
'
' 1. In Normal view, click on the slide you wish to rename
' 2. ALT+F11 to VB Editor
' 3. F5 to run this subroutine
'------------------------------------------------------------------
Sub NameSlide()
Dim curName As String
curName = Application.ActiveWindow.View.Slide.name
Dim newName As String
retry:
newName = InputBox("Enter the new name for slide '" + curName + "', or press Cancel to keep existing name.", "Rename slide")
If Trim(newName) = "" Then Exit Sub
Dim s As Slide
' check if this slide name already exists
On Error GoTo SlideNotFound
Set s = ActivePresentation.Slides(newName)
On Error GoTo 0
MsgBox "Slide with this name already exists!"
GoTo retry
Exit Sub
SlideNotFound:
On Error GoTo 0
Application.ActiveWindow.View.Slide.name = newName
MsgBox "Slide renamed to '" + newName + "'."
End Sub
您无法手动设置幻灯片名称,但通过一些代码,这很简单。例如,在VBA中:
Sub NameThatSlide()
ActivePresentation.Slides(1).Name = "Whatever You Like Here"
End Sub
ActivePresentation.Slides(1).SlideShowTransition.Hidden = msoTrue
Option Explicit
Public Function RenameSlide(oldName As String, newName As String)

' newName: new name for slide.

Dim sld As Slide
Dim RetVal(0 To 1) As String
' Check if oldName can be found.
If SlideExists(oldName) Then
Set sld = Application.ActivePresentation.Slides(oldName)
Else
RetVal(0) = 1 'Error 1
RetVal(1) = "Error 1: slide with name " & oldName & " not found. Aborting."
Exit Function
End If
' Check if this slide name newName already exists.
If SlideExists(newName) Then
RetVal(0) = 2 'Error 1

Exit Function
End If
' Rename the slide
'Application.ActivePresentation.Slides(oldName) = newName
Application.ActivePresentation.Slides(oldName).Select
Application.ActiveWindow.View.Slide.Name = newName 'current slide
RetVal(0) = 0 'Success
RetVal(1) = "Success: slide renamed from '" & oldName & "' to '" & newName & "'."
End Function

'

Dim newName As String

Do While newName = ""
newName = InputBox(msg, "Rename slide")
newName = Trim(newName)
If Len(newName) = 0 Then
msg = "Try again. You must enter a slide name to continue."
ElseIf newName = oldName Or newName = Str(vbCancel) Then
Exit Sub
End If
Loop
' If an existing slide already has name newName, then
' go back and prompt user again.slide name already exists
If SlideExists(newName) Then
msg = "Slide with this name already exists!"
GoTo retry
