使用PowerPoint Interop選擇查看幻燈片母版頁

Question

從C＃中使用的PowerPoint Interop中是否可以通過編程方式將幻燈片母版頁選擇到視圖中，就像選擇常規幻燈片一樣？通過提供該母版頁的ID或從幻燈片中將其作爲模板。

我設法將視圖切換到幻燈片母：

_pptApplication.ActiveWindow.ViewType = PpViewType.ppViewMasterThumbnails; 

我試圖首先選擇幻燈片，然後切換到主視圖，但是該指令總是放入視圖中的第一幻燈片的主頁，而不是與選定幻燈片關聯的那個。

同樣，我想知道這是可能的筆記，講義和他們的主人。

除了設置.ViewType之外，您還需要在CustomLayout對象上使用.Select（）方法。

這裏有兩個例子：

using NetOffice.OfficeApi.Enums; 
using NetOffice.PowerPointApi.Enums; 
using System; 
using PowerPoint = NetOffice.PowerPointApi; 

namespace ExportSlides 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      using (var app = PowerPoint.Application.GetActiveInstance()) 
      { 
       SelectSlideMasterLayoutOfActiveSlide(app); 
       ActiveSlideMasterLayoutByIndex(app.ActivePresentation, 4); 
      } 
     } 

     private static void ActiveSlideMasterLayoutByIndex(PowerPoint.Presentation activePresentation, int customLayoutIndex) 
     { 
      activePresentation.Windows[1].ViewType = PpViewType.ppViewSlideMaster; //PpViewType.ppViewMasterThumbnails doesn't work for me for some reason 
      activePresentation.SlideMaster.CustomLayouts[customLayoutIndex].Select(); 
     } 

     private static void SelectSlideMasterLayoutOfActiveSlide(PowerPoint.Application app) 
     { 
      var activeWindow = app.ActiveWindow; 

      var slideObj = activeWindow.View.Slide; 

      if (slideObj.GetType() == typeof(PowerPoint.Slide)) 
      { 
       var slide = (PowerPoint.Slide)slideObj; 

       activeWindow.ViewType = PpViewType.ppViewSlideMaster; //PpViewType.ppViewMasterThumbnails doesn't work for me for some reason 

       slide.CustomLayout.Select(); 

      } 
     } 
    } 
}
