Edit PPTM Properties using C#

Build .NET apps that read and modify built-in and custom presentation properties with server-side APIs.

Modify PPTM Properties via C#

Using Aspose.Slides for .NET , developers can access and modify built-in and custom presentation properties. Use the DocumentProperties property exposed by a Presentation object to read and update PPTM metadata.

Modify PPTM Built-in Properties - C#using var presentation = new Presentation("presentation.pptm");
var documentProperties = presentation.DocumentProperties;

documentProperties.Author = "Aspose.Slides for .NET";
documentProperties.Title = "Modifying Presentation Properties";
documentProperties.Subject = "Aspose Subject";
documentProperties.Comments = "Aspose Description";
documentProperties.Manager = "Aspose Manager";

presentation.Save("DocumentProperties_out.pptm", SaveFormat.Pptm);

Add Custom Properties to PPTM - C#using var presentation = new Presentation();
var documentProperties = presentation.DocumentProperties;

documentProperties["New Custom"] = 12;
documentProperties["My Name"] = "Aspose Metadata Editor";
documentProperties["Custom"] = 124;

var propertyName = documentProperties.GetCustomPropertyName(2);
documentProperties.RemoveCustomProperty(propertyName);

presentation.Save("CustomDocumentProperties_out.pptm", SaveFormat.Pptm);
