Get Page Count In PDF File

In this tutorial, we’ll walk you through the step-by-step process to get the page count in PDF file using Aspose.PDF for .NET. We’ll explain the bundled C# source code and provide you with a comprehensive guide to help you understand and implement this feature in your own projects. At the end of this tutorial, you will know how to get the page count of a PDF file using Aspose.PDF for .NET.

Prerequisites

Before you begin, make sure you have the following:

  • A basic knowledge of the C# programming language
  • Aspose.PDF for .NET installed in your development environment

Step 1: Instantiate a Document object

First, you need to instantiate a Document object using the Document class of Aspose.PDF.

Document doc = new Document();

Step 2: Add a page to the document

Then you can add a page to the document using the Add() method of the document’s Pages collection.

Page page = doc.Pages.Add();

Step 3: Create page content

Now you can create page content by adding TextFragment objects to the Page object’s Paragraphs collection. In this example, we add a TextFragment repeated 300 times to simulate a document with longer content.

for (int i = 0; i < 300; i++)
page.Paragraphs.Add(new TextFragment("Page count test"));

Step 4: Processing Paragraphs and Getting Page Count

Once you have added the content to the page, you need to process the document paragraphs by calling the ProcessParagraphs() method. This allows Aspose.PDF to calculate the number of pages accurately.

doc.ProcessParagraphs();

Step 5: Displaying the number of pages

Finally, you can view the number of pages in the document by accessing the Count property of the Pages collection.

Console.WriteLine("Number of pages in document = " + doc.Pages.Count);

Sample source code for Get Page Count using Aspose.PDF for .NET


// Instantiate Document instance
Document doc = new Document();
// Add page to pages collection of PDF file
Page page = doc.Pages.Add();
// Create loop instance
for (int i = 0; i < 300; i++)
	// Add TextFragment to paragraphs collection of page object
	page.Paragraphs.Add(new TextFragment("Pages count test"));
// Process the paragraphs in PDF file to get accurate page count
doc.ProcessParagraphs();
// Print number of pages in document
Console.WriteLine("Number of pages in document = " + doc.Pages.Count);

Conclusion

In this tutorial, we learned how to get the page count of a PDF file using Aspose.PDF for .NET. By following the steps outlined above, you can easily implement this functionality in your own projects.
