C＃VSTO PowerPoint加载项另存为PDF [英] C# VSTO PowerPoint Add-In Save As PDF

问题描述

我想在关闭PowerPoint之前保存我的演示文稿，但是作为PDF格式。我如何在
ThisAddIn_Shutdown中使用ppSaveAsPDF？

谢谢

解决方案

您好，

ThisAddIn_Shutdown
事件o 在即将卸载加载项时发生。

我建议您处理
Application.PresentationBeforeClose活动&
使用Presentation.ExportAsFixedFormat方法保存为PDF。

例如

 private void ThisAddIn_Startup（object sender，System.EventArgs e）
 {
 PPT.Application app = Globals.ThisAddIn.Application; 
 app.PresentationBeforeClose + = App_PresentationBeforeClose; 
} 
 
 private void App_PresentationBeforeClose（PPT.Presentation Pres，ref bool Cancel）
 {
 PPT.Application app = Globals.ThisAddIn.Application; 
 PPT.Presentation pre = app.ActivePresentation; 
 pre.ExportAsFixedFormat（@" C：\Users\Admin \Desktop\Test.pdf"，PPT.PpFixedFormatType.ppFixedFormatTypePDF）; 
} 
 

问候，

解决方案

Hello,

ThisAddIn_Shutdown event occurs when the add-in is about to be unloaded.

I suggest you handle Application.PresentationBeforeClose Event and use Presentation.ExportAsFixedFormat Method to save as PDF.

E.g.

private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            PPT.Application app = Globals.ThisAddIn.Application;
            app.PresentationBeforeClose += App_PresentationBeforeClose;
        }

        private void App_PresentationBeforeClose(PPT.Presentation Pres, ref bool Cancel)
        {
            PPT.Application app = Globals.ThisAddIn.Application;
            PPT.Presentation pre = app.ActivePresentation;
            pre.ExportAsFixedFormat(@"C:\Users\Admin\Desktop\Test.pdf", PPT.PpFixedFormatType.ppFixedFormatTypePDF);
        }
