How to create a PDF and load to PdfViewer without saving to disk?

New PDF documents can be created from scratch using the PdfDocument class and save it into a stream, and the stream can be loaded into PdfViewer. So that, saving the document in the disk can be avoided.

Portable/.NET Standard

Add PdfViewer to the MainPage of the application.

XAML

Add a method named “CreateNewPDF” with return type Stream in the code behind of the MainPage. In this method create a PdfDocument instance, set its page size, add a new page to it, and draw the string “Hello World!” on the page. Now, save this PdfDocument instance to a stream and return this stream.

C#

The previous example illustrates drawing a simple string on a single page PDF. Refer to the following documentation for creating PDF with more pages and different types of contents such as text, images, tables and more.
