Following our previous post about Azure AI Translator, this post will show how to translate text between a source and target language using C#.<\/p>\n\n\n\n\n\n\n\n

About Azure AI Translator<\/h2>\n\n\n\n

Microsoft Azure AI Translator offers translation services like language detection and translation for over 90 languages using a single API endpoint.<\/p>\n\n\n\n

The process to use Azure AI Translator starts with the provisioning of an Azure AI Service (Multi-service or Translator) and using an SDK or Azure REST API to use the service.<\/p>\n\n\n\n

Azure AI Translator offers two core services: Language detection and Language translations. To use the detection service, we need to send a text in a key-value pair format with the language that we would like to detect.<\/p>\n\n\n\n

The translation service uses two parameters, From and To, that indicate the source (From) and target (To) languages. We can also count the number of characters in a translated sentence using built-in functions that come with the API.<\/p>\n\n\n\n

How to Translate Text Using Azure AI Translator and .NET<\/h2>\n\n\n\n

The following C# program uses the Azure AI Translator REST API endpoint to translate text (Source to Target). To get started, create a C# project and install the Translation library<\/a>.<\/p>\n\n\n\n

dotnet add package Azure.AI.Translation.Text --version 1.0.0-beta.1<\/code><\/pre>\n\n\n\n
In your .NET project, create a appsettings.json<\/strong><\/code> file with the details of your access key and region.<\/p>\n\n\n\n
{\n    \"TranslatorKey\": \"ACCESS KEY\",\n    \"TranslatorRegion\": \"AZURE REGION\"\n}\n<\/code><\/pre>\n\n\n\n
In your Programs.cs<\/code> file, add the following code.<\/p>\n\n\n\n
