How to create Word document in Linux Docker in C#?

Docker is an open platform for developing, shipping, and running applications. You can use Essential® .NET Core DocIO in a Docker container to create, read, write, and convert Microsoft Word documents into various formats. You can learn how to create a Word document in Linux Docker using the Syncfusion® Word library (Essential® DocIO) from this page.

Steps to create a Word document in Linux Docker:

1. Create a new Core Console application.

2. Install the Syncfusion.DocIO.Net.Core NuGet package to reference your project from NuGet.org.

3. Include the following namespaces in the Program.cs file:

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

4. Add the following code snippet in the Program.cs file:

   // Creating a new document.
    WordDocument document = new WordDocument();
   // Adding a new section to the document.
   WSection section = document.AddSection() as WSection;
   // Set Margin of the section
   section.PageSetup.Margins.All = 72;
   //Set page size of the section
   section.PageSetup.PageSize = new Syncfusion.Drawing.SizeF(612, 792);
    
   // Create Paragraph styles
   WParagraphStyle style = document.AddParagraphStyle("Normal") as WParagraphStyle;
   style.CharacterFormat.FontName = "Calibri";
   style.CharacterFormat.FontSize = 11f;
   style.ParagraphFormat.BeforeSpacing = 0;
   style.ParagraphFormat.AfterSpacing = 8;
   style.ParagraphFormat.LineSpacing = 13.8f;
    
   style = document.AddParagraphStyle("Heading 1") as WParagraphStyle;
   style.ApplyBaseStyle("Normal");
   style.CharacterFormat.FontName = "Calibri Light";

5. Add Docker support to that application by clicking Add -> Docker Support.

6. Choose the Linux option to run the application in the Linux Docker container.

7. Open the Dockerfile to see the default Docker commands below.

   FROM mcr.microsoft.com/dotnet/runtime:3.1 AS base
   WORKDIR /app
    
   FROM mcr.microsoft.com/dotnet/sdk:3.1 AS build
   WORKDIR /src
   COPY ["CreateWordDocument.csproj", "."]
   RUN dotnet restore "./CreateWordDocument.csproj"
   COPY . .
   WORKDIR "/src/."
   RUN dotnet build "CreateWordDocument.csproj" -c Release -o /app/build
    
   FROM build AS publish
   RUN dotnet publish "CreateWordDocument.csproj" -c Release -o /app/publish
    
   FROM base AS final
   WORKDIR /app
   COPY --from=publish /app/publish .
   ENTRYPOINT ["dotnet", "CreateWordDocument.dll"]
   

8. Select the Docker option and run the application.

A complete working example of creating a Word document in a Linux Docker container can be downloaded here.

By executing the program, you will get the output Word document as follows.

Take a moment to peruse the documentation, where you can find basic Word document processing options and features like mail merge, merge and split documents, find and replace text in the Word document, protect Word documents, and most importantly, PDF and image conversions with code examples.
