Get the titles of all the slides in a presentation

This topic shows how to use the classes in the Open XML SDK for Office to get the titles of all slides in a presentation programmatically.

Getting a PresentationDocument Object

In the Open XML SDK, the PresentationDocument class represents a presentation document package. To work with a presentation document, first create an instance of the PresentationDocument class, and then work with that instance. To create the class instance from the document call the PresentationDocument.Open(String, Boolean) method that uses a file path, and a Boolean value as the second parameter to specify whether a document is editable. To open a document for read-only, specify the value false for this parameter as shown in the following using statement. In this code, the presentationFile parameter is a string that represents the path for the file from which you want to open the document.

C#

    // Open the presentation as read-only.
    using (PresentationDocument presentationDocument = PresentationDocument.Open(presentationFile, false))
    {
        // Insert other code here.
    }

Visual Basic

    ' Open the presentation as read-only.
    Using presentationDocument As PresentationDocument = PresentationDocument.Open(presentationFile, False)
        ' Insert other code here.
    End Using

The using statement provides a recommended alternative to the typical .Open, .Save, .Close sequence. It ensures that the Dispose method (internal method used by the Open XML SDK to clean up resources) is automatically called when the closing brace is reached. The block that follows the using statement establishes a scope for the object that is created or named in the using statement, in this case presentationDocument.

Sample Code

The following is the complete sample code that you can use to get the titles of the slides in a presentation file. For example you can use the following foreach statement in your program to return all the titles in the presentation file, "Myppt9.pptx."

C#

    foreach (string s in GetSlideTitles(@"C:\Users\Public\Documents\Myppt9.pptx"))
       Console.WriteLine(s);

Visual Basic

    For Each s As String In GetSlideTitles("C:\Users\Public\Documents\Myppt9.pptx")
       Console.WriteLine(s)
    Next

---

The result would be a list of the strings that represent the titles in the presentation, each on a separate line.

Following is the complete sample code in both C# and Visual Basic.
