To update the Table of Contents (TOC) in a document using Aspose.Words for .NET, you can use the UpdateFields method followed by the UpdatePageLayout method. This sequence is essential to ensure that the TOC is populated correctly and that the page numbers are displayed accurately.

Here’s a sample code snippet demonstrating how to achieve this:

using Aspose.Words;

class Program
{
    static void Main()
    {
        // Load the document
        Document doc = new Document("YourDocument.docx");

        // Update all fields in the document, including the TOC
        doc.UpdateFields();

        // Update the page layout to ensure page numbers are calculated
        doc.UpdatePageLayout();

        // Save the updated document
        doc.Save("UpdatedDocument.docx");
    }
}

In this example:

  1. The document is loaded from a file.
  2. The UpdateFields method is called to update all fields, including the TOC.
  3. The UpdatePageLayout method is then called to calculate the layout and page numbers.
  4. Finally, the updated document is saved.

Make sure to replace "YourDocument.docx" and "UpdatedDocument.docx" with the actual paths of your input and output files. This approach will ensure that your TOC is correctly updated with the latest entries and page numbers.

For more detailed information, you can refer to the official documentation on updating fields and working with the Table of Contents in Aspose.Words for .NET.
