Create Word document in Azure Functions v1

22 Jul 202616 minutes to read

Syncfusion^® DocIO is a .NET Word library used to create, read, edit and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can create a Word document in Azure Functions v1.

Prerequisites

An active Azure subscription.
Visual Studio with the Azure development workload installed.

Steps to create a Word document in Azure Functions v1

Step 1: Create a new Azure Functions project. Select the Azure Functions template for .NET Framework in Visual Studio.
Create a Azure Functions project

Step 2: Create a project name and select the location.

Step 3: Select the function worker as .NET Framework.
Select function worker

Step 4: Install the Syncfusion.DocIO.AspNet NuGet package (v16.2.0.x or later) as a reference to your project from NuGet.org.
Install Syncfusion.DocIO.AspNet NuGet package

NOTE

Starting with v16.2.0.x, if you reference Syncfusion^® assemblies from the trial setup or from the NuGet feed, you must add a reference to the Syncfusion.Licensing assembly and include a valid license key in your application.

Install the Syncfusion.Licensing NuGet package and register the license key during application startup.
Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR_LICENSE_KEY");
For more information about generating and registering a license key, refer to the Syncfusion^® licensing documentation.

Step 5: Include the following namespaces in the Function1.cs file.

C#
using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

The code in Step 6 also requires the following namespaces:

C#
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using System;
using System.Drawing;
using System.IO;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Reflection;

Step 6: Add the following code snippet in the Run method of the Function1 class to create a Word document in Azure Functions and return the resulting Word document to the client.

C#
// 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

Step 12: Click the Publish button.
Click Publish Button

Step 13: Publish has succeeded.
Publish succeeded

Step 14: Go to the Azure portal and select App Services. Start the service and copy the Get Function URL. Paste it into the client sample in the next section, which requests the Azure Functions to create a Word document. You will receive the resulting Word document as shown below.

Create a Word document in Azure Functions v1

Steps to post the request to Azure Functions

Step 1: Create a .NET console application to request the Azure Functions API. No Syncfusion NuGet package is required on the client side.

Step 2: Add the following code snippet into the Main method to send a request to the Azure Functions and save the resulting Word document.

C#
//Reads the template Word document.
FileStream fs = new FileStream(@"../../Data/Input.docx", FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);
fs.Position = 0;
//Saves the Word document in memory stream.
MemoryStream inputStream = new MemoryStream();
fs.CopyTo(inputStream);
inputStream.Position = 0;
try
{
    Console.WriteLine("Please enter your Azure Functions URL :");
    string functionURL = Console.ReadLine();
    //Create HttpWebRequest with hosted azure functions URL.
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(functionURL);
    //Set request method as POST
    req.Method = "POST";
    //Get the request stream to save the Word document stream
    Stream stream = req.GetRequestStream();
    //Write the Word document stream into request stream
    stream.Write(inputStream.ToArray(), 0, inputStream.ToArray().Length);
    //Gets the responce from the Azure Functions.
    HttpWebResponse res = (HttpWebResponse)req.GetResponse();
    //Saves the Word document stream.
    FileStream fileStream = File.Create("Sample.docx");
    res.GetResponseStream().CopyTo(fileStream);
    //Dispose the streams
    inputStream.Dispose();
    fileStream.Dispose();
}
catch (Exception ex)
{
    Console.WriteLine("Error: " + ex.Message);
}

From GitHub, you can download the console application and Azure Functions v1.

NOTE

The code sample references image files (AdventureCycle.jpg, Mountain-200.jpg, Mountain-300.jpg, Road-550-W.jpg). Download these assets from the GitHub sample Data folder and add them to a Data folder in the Functions project with their Build Action set to Embedded Resource so the GetManifestResourceStream calls resolve correctly at runtime.
