This tutorial describes how to create a simple Office File API application for .NET on macOS.

Prerequisites

Add Common Libraries

• The .NET library of the required version.

• Optional. If your application needs to render JPEG images within PDF files, install the following package:

  brew install jpeg-turbo
  

Add Drawing Engine Libraries

Make sure that you add the DevExpress.Drawing.Skia package to your application to use the SkiaSharp-Based drawing engine.

If you use the the System.Drawing.Common package v7 and later, the Skia-based engine is enabled automatically and the libgdiplus library is not required. Refer to the following article for more information on the drawing engines: DevExpress.Drawing Graphics Library

Create the Application

Create a folder for you project (OfficeConsoleApp in this example) and open this folder in Visual Studio Code.

Click View → Terminal in the main menu to open the integrated terminal.

Use the dotnet new command to create a new console application.

Create a C# project

dotnet new console

Create a VB project

dotnet new console -lang VB

This command adds the following files to your folder:

• OfficeConsoleApp.csproj / OfficeConsoleApp.vbproj

• Program.cs / Program.vb.

Add DevExpress.Document.Processor Package

Obtain your NuGet Feed URL and install the DevExpress.Document.Processor NuGet package as described in the following topic: Use NuGet Packages to Install Office File API Components.

Add the DevExpress.Pdf.SkiaRenderer package to enable rendering of PDF page content within your app.

Important

You need a license for the DevExpress Office File API Subscription or DevExpress Universal Subscription to use this package in production code.

Insert Code

Paste the code below in the Main method of the Program.cs file (or Program.vb file’s Main procedure for Visual Basic). The following example converts a DOCX file to PDF:

C#

using DevExpress.XtraRichEdit;
// ...

static void Main(string[] args) {
    using (var documentProcessor =
        new RichEditDocumentServer()) {
        // Load a document from a file.
        documentProcessor.LoadDocument("Document.docx", DocumentFormat.OpenXml);
        // Export the document to PDF.
        documentProcessor.ExportToPdf("PdfDocument.pdf");
    }
}

VB.NET

Imports DevExpress.XtraRichEdit
' ...

Sub Main(args As String())
    Using documentProcessor As RichEditDocumentServer = New RichEditDocumentServer()
        ' Load a document from a file.
        documentProcessor.LoadDocument("Document.docx", DocumentFormat.OpenXml)
        ' Export the document to PDF.
        documentProcessor.ExportToPdf("PdfDocument.pdf")
    End Using
End Sub

Run the Application

Type dotnet run in the terminal window to run the program.

dotnet run

The following image illustrates the result. This tutorial uses Visual Studio Code.
