How to Mark a Presentation as Final using Spire.Presentation in C#, VB.NET

The Mark as Final command makes a presentation read-only and prevents changes to the document. When you share a presentation that is marked as final, you're telling viewers the presentation is final and no changes on it are wanted. In this article, I'll make a brief introduction about how to mark a presentation as final using Spire.Presentation in C#, VB.NET.

In Spire.Presentation, the presentation class contains a property of DocumentProperty which enables developers to set document properties easily. Here in this case, you are able to mark a presentation as final by setting the Boolean value of MarkAsFinal as true.

Code Snippet:

Step 1: Initialize a new instance of presentation class and load the sample file.

Presentation ppt = new Presentation();
ppt.LoadFromFile("sample.pptx",FileFormat.Pptx2010);

Step 2: Set the value of MarkAsFinal property as true.

ppt.DocumentProperty["_MarkAsFinal"] =true;

Step 3: Save and launch the file.

ppt.SaveToFile("result.pptx",FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
