Converting Word document to PDF in ASP.NET Core

Syncfusion® Essential® DocIO Renderer is a .NET Core Word to PDF conversion library (Essential® DocIO and Essential® PDF) used to convert Word documents to PDF in ASP.NET Core applications [C#].

Steps to convert a Word document to PDF programmatically in ASP.NET Core:

1. Create a new C# .NET Core console application.

2. Install the Syncfusion.DocIORenderer.NET.Core NuGet package as a reference to your .NET Core application from NuGet.org.

3. Include the following namespace in the Program.cs file.

C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIORenderer;
using Syncfusion.Pdf;
using System.IO;

4. Use the following code snippet to create a Word document with “Hello World” text and convert the Word document to PDF.

C#

// Creates a new Word document.
WordDocument wordDocument = new WordDocument();
// Add a section and a paragraph in the empty document.
wordDocument.EnsureMinimal();
// Append text to the last paragraph of the document.
wordDocument.LastParagraph.AppendText("Hello World...!");
// Create an instance for DocIORenderer for Word to PDF conversion.
DocIORenderer render = new DocIORenderer();
// Converts Word document to PDF.
PdfDocument pdfDocument = render.ConvertToPDF(wordDocument);
// Release the resources used by the Word document and DocIO Renderer objects.
render.Dispose();
wordDocument.Dispose();
// Save the PDF file.
FileStream outputStream = new FileStream(@"Output.pdf", FileMode.CreateNew, FileAccess.Write);
pdfDocument.Save(outputStream);
// Close the instance of the PDF document object.
pdfDocument.Close();
// Dispose of the instance of FileStream.
outputStream.Dispose();
