DeepL 0.4.1

DeepL.NET

IMPORTANT This is not an official .NET binding for DeepL and is neither created nor officially supported by DeepL. DeepL provides their own .NET client library, which can be found here.

An unofficial, fully-featured .NET client for the DeepL translation service. DeepL is a commercial translation service based on deep learning. This API client only supports v2 of the API as v1 has been deprecated for new DeepL API plans available from October 2018.

Features

• .NET Core and .NET Framework compatible
• Completely asynchronous (using the async-await pattern)
• Covers the complete surface area of the DeepL API
• Translate text (including text with XML markup)
• Translate documents (Word, PowerPoint, HTML, and raw text documents)

Getting Started

To get started you have to add the package reference to your project:

Install-Package DeepL -Version 0.4.1 # Package Manager
dotnet add package DeepL --version 0.4.1 # .NET CLI
paket add DeepL --version 0.4.1 # Paket CLI

or manually add a reference to your project file:

<PackageReference Include="DeepL" Version="0.4.1" />

Then you can start translating texts:

using DeepL;

namespace Application
{
    public class Program
    {
        public static async Task Main(string[] arguments)
        {
            using (DeepLClient client = new DeepLClient("<authentication key>", useFreeApi: false))
            {
                try
                {
                    Translation translation = await client.TranslateAsync(
                        "This is a test sentence.",
                        Language.German
                    );
                    Console.WriteLine(translation.DetectedSourceLanguage);
                    Console.WriteLine(translation.Text);
                }
                catch (DeepLException exception)
                {
                    Console.WriteLine($"An error occurred: {exception.Message}");
                }
            }
        }
    }
}

For a more complex example, please refer to the sample application, which is a fully-featured command line tool that demonstrates the usage of all DeepL.NET features. For a complete overview of DeepL.NET, please refer to the documentation.
