// Step 3: Add content to the page.
PdfGraphics graphics = page.Graphics;
graphics.DrawString("Hello, World!", new PdfStandardFont(PdfFontFamily.Helvetica, 12), PdfBrushes.Black, new PointF(10, 10));

// Step 4: Save the PDF to a memory stream.
MemoryStream stream = new MemoryStream();
document.Save(stream);
document.Close(true);
// Reset the stream position so the upload can read it from the beginning.
stream.Position = 0;

// Step 5: Upload the PDF to Google Cloud Storage.
// Load the credentials file. Replace with the path to your actual credentials.json.
GoogleCredential credential = GoogleCredential.FromFile("credentials.json");

// Create a storage client.
StorageClient storage = StorageClient.Create(credential);

// Upload the PDF to the specified bucket and object name.
storage.UploadObject("YOUR_BUCKET_NAME", "Sample.pdf", null, stream);
