Ensure once whether all the following dependency packages are included within the project.json file as mentioned here, to create and manipulate the PDF documents using Essential PDF.
To create a PDF document the following assemblies have to be added as reference to the project.
| Assembly Name | Description |
|---|---|
| Syncfusion.Pdf.AspNet.Core | This assembly contains the core feature for creating, manipulating and saving PDF documents. |
| Syncfusion.Compression.AspNet.Core | This assembly is required for compressing the internal contents of a PDF document. |
Include the following namespaces in your .cs file as shown below.
using Syncfusion.Pdf;
using Syncfusion.Pdf.Parsing;
using Syncfusion.Pdf.Graphics;
using Syncfusion.Pdf.Grid;Creating a PDF document with simple text
The following code example shows how to create a PDF document with simple text.
//Create a new PDF document.
PdfDocument document = new PdfDocument();
//Add a page to the document.
PdfPage page = document.Pages.Add();
//Create PDF graphics for the page.
PdfGraphics graphics = page.Graphics;
//Set the standard font.
PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20);
//Draw the text.
graphics.DrawString("Hello World!!!", font, PdfBrushes.Black, new PointF(0, 0));
//Save the document.
document.Save("Output.pdf");
//Close the document.
document.Close(true);Saving the document
The following code example illustrates how to download the PDF document in browser after saving the document.
//Create a new PDF document
PdfDocument document = new PdfDocument();
//Add a page to the document
PdfPage page = document.Pages.Add();
//Create PDF graphics for the page
PdfGraphics graphics = page.Graphics;
//Draw the rectangle
graphics.DrawRectangle(PdfPens.Black, new RectangleF(0, 0, 100, 100));
//Saving the PDF to the MemoryStream
MemoryStream ms = new MemoryStream();
document.Save(ms);
//If the position is not set to '0' then the PDF will be empty.
ms.Position = 0;
//Download the PDF document in the browser.
FileStreamResult fileStreamResult = new FileStreamResult(ms, "application/pdf");
fileStreamResult.FileDownloadName = "Sample.pdf";
return fileStreamResult;
