Edit OTP properties using C#

Build your own .NET apps to modify Built-in and Custom properties in presentation files using server-side APIs.

Modify OTP Properties via C#

Using Aspose.Slides for .NET, developers can access and modify the values of built-in properties as well as custom properties. Developers can use DocumentProperties property exposed by Presentation object to access the document properties of the presentation file.

Modify OTP Built-in Properties - C#
// Instantiate the Presentation class that represents the Presentation
Presentation presentation = new Presentation("presentation.otp");

// Create a reference to IDocumentProperties object associated with Presentation
IDocumentProperties documentProperties = presentation.DocumentProperties;

// Set the builtin properties
documentProperties.Author = "Aspose.Slides for .NET";
documentProperties.Title = "Modifying Presentation Properties";
documentProperties.Subject = "Aspose Subject";
documentProperties.Comments = "Aspose Description";
documentProperties.Manager = "Aspose Manager";

// Save your presentation to a file
presentation.Save("DocumentProperties_out.otp", SaveFormat.Otp);

Add Custom Properties to OTP - C#
// Instantiate the Presentation class
Presentation presentation = new Presentation();

// Getting Document Properties
IDocumentProperties documentProperties = presentation.DocumentProperties;

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

// Getting property name at particular index
String getPropertyName = documentProperties.GetCustomPropertyName(2);

// Removing selected property
documentProperties.RemoveCustomProperty(getPropertyName);

// Save your presentation to a file
presentation.Save("CustomDocumentProperties_out.otp", SaveFormat.Otp);
