Use this quickstart to create a Personally Identifiable Information (PII) detection application with the client library for .NET. In the following example, you create a C# application that can identify recognized sensitive information in text.

Tip

You can use Language Studio to try PII detection in documents without needing to write code.

Prerequisites

Setting up

Create an Azure resource

To use the code sample below, you'll need to deploy an Azure resource. This resource will contain a key and endpoint you'll use to authenticate the API calls you send to the Language service.

  1. Use the following link to create a language resource using the Azure portal. You will need to sign in using your Azure subscription.

  2. On the Select additional features screen that appears, select Continue to create your resource.

    A screenshot showing additional feature options in the Azure portal.

  3. In the Create language screen, provide the following information:

    Detail Description
    Subscription The subscription account that your resource will be associated with. Select your Azure subscription from the drop-down menu.
    Resource group A resource group is a container that stores the resources you create. Select Create new to create a new resource group.
    Region The location of your Language resource. Different regions may introduce latency depending on your physical location, but have no impact on the runtime availability of your resource. For this quickstart, either select an available region near you, or choose East US.
    Name The name for your Language resource. This name will also be used to create an endpoint URL that your applications will use to send API requests.
    Pricing tier The pricing tier for your Language resource. You can use the Free F0 tier to try the service and upgrade later to a paid tier for production.

    A screenshot showing resource creation details in the Azure portal.

  4. Make sure the Responsible AI Notice checkbox is checked.

  5. Select Review + Create at the bottom of the page.

  6. In the screen that appears, make sure the validation has passed, and that you entered your information correctly. Then select Create.

Get your key and endpoint

Next you will need the key and endpoint from the resource to connect your application to the API. You'll paste your key and endpoint into the code later in the quickstart.

  1. After the Language resource deploys successfully, click the Go to Resource button under Next Steps.

    A screenshot showing the next steps after a resource has deployed.

  2. On the screen for your resource, select Keys and endpoint on the left navigation menu. You will use one of your keys and your endpoint in the steps below.

    A screenshot showing the keys and endpoint section for a resource.

Create environment variables

Your application must be authenticated to send API requests. For production, use a secure way of storing and accessing your credentials. In this example, you will write your credentials to environment variables on the local machine running the application.

To set the environment variable for your Language resource key, open a console window, and follow the instructions for your operating system and development environment.

  • To set the LANGUAGE_KEY environment variable, replace your-key with one of the keys for your resource.
  • To set the LANGUAGE_ENDPOINT environment variable, replace your-endpoint with the endpoint for your resource.

Important

If you use an API key, store it securely somewhere else, such as in Azure Key Vault. Don't include the API key directly in your code, and never post it publicly.

For more information about AI services security, see Authenticate requests to Azure AI services.

setx LANGUAGE_KEY your-key

setx LANGUAGE_ENDPOINT your-endpoint

Note

If you only need to access the environment variables in the current running console, you can set the environment variable with set instead of setx.

After you add the environment variables, you may need to restart any running programs that will need to read the environment variables, including the console window. For example, if you are using Visual Studio as your editor, restart Visual Studio before running the example.

Create a new .NET Core application

Using the Visual Studio IDE, create a new .NET Core console app. This creates a "Hello World" project with a single C# source file: program.cs.

Install the client library by right-clicking on the solution in the Solution Explorer and selecting Manage NuGet Packages. In the package manager that opens select Browse and search for Azure.AI.TextAnalytics. Select version 5.2.0, and then Install. You can also use the Package Manager Console.

Code example

Copy the following code into your program.cs file and run the code.

using Azure;
using System;
using Azure.AI.TextAnalytics;

namespace Example
{
    class Program
    {
        // This example requires environment variables named "LANGUAGE_KEY" and "LANGUAGE_ENDPOINT"
        static string languageKey = Environment.GetEnvironmentVariable("LANGUAGE_KEY");
        static string languageEndpoint = Environment.GetEnvironmentVariable("LANGUAGE_ENDPOINT");

        private static readonly AzureKeyCredential credentials = new AzureKeyCredential(languageKey);
        private static readonly Uri endpoint = new Uri(languageEndpoint);

        // Example method for detecting sensitive information (PII) from text 
        static void RecognizePIIExample(TextAnalyticsClient client)
        {
            string document = "Call our office at 312-555-1234, or send an email to support@contoso.com.";
        
            PiiEntityCollection entities = client.RecognizePiiEntities(document).Value;
        
            Console.WriteLine($"Redacted Text: {entities.RedactedText}");
            if (entities.Count > 0)
            {
                Console.WriteLine($"Recognized {entities.Count} PII entit{(entities.Count > 1 ? "ies" : "y")}:");
                foreach (PiiEntity entity in entities)
                {
                    Console.WriteLine($"Text: {entity.Text}, Category: {entity.Category}, SubCategory: {entity.SubCategory}, Confidence score: {entity.ConfidenceScore}");
                }
            }
            else
            {
                Console.WriteLine("No entities were found.");
            }
        }

        static void Main(string[] args)
        {
            var client = new TextAnalyticsClient(endpoint, credentials);
            RecognizePIIExample(client);

            Console.Write("Press any key to exit.");
            Console.ReadKey();
        }

    }
}

Output

Redacted Text: Call our office at ************, or send an email to *******************.
Recognized 2 PII entities:
Text: 312-555-1234, Category: PhoneNumber, SubCategory: , Confidence score: 0.8
