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");
Effect:
Full Code:
using Spire.Presentation;
namespace MarkPPT
{
class Program
{
static void Main(string[] args)
{
Presentation ppt = new Presentation();
ppt.LoadFromFile("sample.pptx", FileFormat.Pptx2010);
ppt.DocumentProperty["_MarkAsFinal"] = true;
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
System.Diagnostics.Process.Start("result.pptx");
}
}
}
Imports Spire.Presentation
Namespace MarkPPT
Class Program
Private Shared Sub Main(args As String())
Dim ppt As New Presentation()
ppt.LoadFromFile("sample.pptx", FileFormat.Pptx2010)
ppt.DocumentProperty("_MarkAsFinal") = True
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010)
System.Diagnostics.Process.Start("result.pptx")
System.Diagnostics.Process.Start("result.pptx")
End Sub
End Class
End Namespace
