Create ASP.NET Core application using Visual Studio 2019 and use the Translator Text API Key.

Before starting the actual functionality, we need to know What is Azure Cognitive Services Translator Text API? and the Prerequisites needed for the development of this functionality.

What is Azure Cognitive Services Translator Text API?

The Translator Text API is a part of Azure Cognitive Services, an AI service from Microsoft that helps you to translate the text to multiple languages easily. Azure Cognitive Services Translator Text API supports more than 70 languages for the translation.

There are some key benefits of using the Azure Cognitive Services Translator Text API. Those are as below

It supports more than 70 languages which is the biggest advantage.
You can build custom models for the translation based on your business-specific requirement.
As security plays an important role, so it provides Built-in security for your Data. Your Data is safe.

We have a few ideas now on the Microsoft Translator Text API. Now let’s discuss the Prerequisites needed for implementing the functionality here.

Create a Microsoft Translator Text API Azure Portal

On the Create a new ASP.NET Core web application window, select the web Application project template and then click on the Create button to create the project.

Now the Project will get created successfully with out any issue

Now we need to add the code needed for the functionality. You need to do the below changes in the Index.cshtml file.

Azure Cognitive Services Translator Text API example

Now, you need to add the code for the site.js file as the below

$(function () {
    $(document)
        .on('change', '#ddlLCode', function () {
            var langCode = $(this).val();
            var eText = $("#idText").val();
            if (1 <= $("#idText").val().trim().length && languageCode != "NA") {

                $('#idText').removeClass('redBorder');

                var url = '/Home/Index';
                var dataToSend = { "LanguageCode": langCode, "Text": eText };
                dataType: "json",
                    $.ajax({
                        url: url,
                        data: dataToSend,
                        type: 'POST',
                        success: function (response) {
                           
                            var result = JSON.parse(response);
                            var tText = result[0].translations[0].text;
                            $('#idtransText').val(tText);
                        }
                    })
            }
            else {
                $('#idText').addClass('redBorder');
                $('#idtransText').val("");
            }
        });
});

Now the next steps are to create the interface named as ITextTranslation and that should contain the below lines of code

namespace DemoTranslateAPP
{
    interface ITextTranslation
    {
        Task<string> Translation(string uri, string text, string key);
    }
}

Now the next is to create the TextTranslationService and that should contain the below code

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace DemoTranslateAPP
{
    public class TextTranslationService : ITextTranslation
    {
        public async Task<string> Translation(string uri, string text, string key)
        {
            System.Object[] body = new System.Object[] { new { Text = text } };
            var requestBody = JsonConvert.SerializeObject(body);

            using (var cnt = new HttpClient())
            using (var rqst = new HttpRequestMessage())
            {
                rqst.Method = HttpMethod.Post;
                rqst.RequestUri = new Uri(uri);
                rqst.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
                rqst.Headers.Add("Ocp-Apim-Subscription-Key", key);

                var rspns = await cnt.SendAsync(rqst);
                var responseBody = await rspns.Content.ReadAsStringAsync();
                dynamic result = JsonConvert.SerializeObject(JsonConvert.DeserializeObject(responseBody), Formatting.Indented);

                return result;
            }
        }
    }
}

Note: Don’t forget to inject the TextTranslationService and ITextTranslation in the startup.cs class file.

Now we are done with the changes, press F5 to run the project. Now the project should run successfully without any issue.

The JSON response will be something like below

[  
  {  
    "detectedLanguage": {  
      "language": "en",  
      "score": 1.0  
    },  
    "translations": [  
      {  
        "text": "भगवान आपका भला करे",  
        "to": "God is Great"  
      }  
    ]  
  }  
]

Enter the text and the text will get transferred to the language present in the drop-down list.

This is how you can work with Azure Cognitive Services Translator Text API ASP.NET Core. We have discussed one of the Azure Cognitive Services Translator Text API Example.

Microsoft Translator API Example

Well, here we will discuss another example of the implementation of Azure Cognitive Services Translator Text API. Here in this example, we will perform the below steps

We will create an Azure Cognitive Services Translator Text API in the Azure Portal
We will create a console application and we will use the Translator Text API there.

How To Create a Microsoft Translator Text API Using Azure Portal

The first step is to create a Microsoft Translator Text API Using Azure Portal. Since we have already created the Microsoft Translator Text API using the Azure Portal above. You can refer to the Create a Microsoft Translator Text API in Azure Portal section of the article to create the Microsoft Translator Text API.

So I am going to use the same Azure Cognitive Services Translator Text API that I have created above. Below is the Translator Text API that I have already created above.

So copy the Key1 value to a notepad that we are going to use in the console application which we are going to create in the next step. Click on the Copy button next to the Key1 value as highlighted below. You can also click on the Regenerate key1 or Regenerate key2 and copy the new key-value if you want to use the new key value.

Now the Project will create successfully with out any issue.

Now the next step is to add the NuGet Package i.e Newtonsoft.Json to the project. To add the NuGet package, Right-click on the Project and then choose Manage NuGet Packages.

Now From the below window select the Browse tab and search for the Network.json and select the NuGet package and click on the Install button to install the NuGet package as highlighted below.

Now on the Program.cs file add the below using statement

using Newtonsoft.Json;

Now on the same Program.cs file, Add the rest of the code as below. Below is the complete code for the Program.cs file.

Note: Make sure to change the value for the Key-Value(Put the key value of your Azure Translator Text API that you have copied in the above step ) and then also change the value for the Ocp-Apim-Subscription-Region value (This should be the Region for your Azure Translator Text API. For me, it is eastus).

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;
using Newtonsoft.Json;



namespace DemoTranslatorAPI
{
    
   public class Program
    {
        private const string key = "db0746e18e27457fbe3ed52ba6188753";

        public static async Task Main()

        {
            while (true)
            {
                var text = Console.ReadLine();

                var lang = Console.ReadLine();
                Translate(text, lang);
            }
        }
        public static async void Translate(string text, string language)
        {
            var encodtxt = WebUtility.UrlEncode(text);
            string texttotranslate = text;

            string uri = $"https://api.cognitive.microsofttranslator.com//translate?api-version=3.0&from=en&to={language}";

            System.Object[] body = new System.Object[] { new { Text = texttotranslate } };
            var requestBody = JsonConvert.SerializeObject(body);

            using (var client = new HttpClient())
            using (var request = new HttpRequestMessage())
            {
                request.Method = HttpMethod.Post;
                request.RequestUri = new Uri(uri);
                request.Content = new StringContent(requestBody, Encoding.UTF8, "application/json");
                request.Headers.Add("Ocp-Apim-Subscription-Key", key);
                request.Headers.Add("Ocp-Apim-Subscription-Region", "eastus");
                var response = await client.SendAsync(request);
                var responseBody = await response.Content.ReadAsStringAsync();

                var result = JsonConvert.DeserializeObject<List<Dictionary<string, List<Dictionary<string, string>>>>>(responseBody);
                var translation = result[0]["translations"][0]["text"];

                Console.WriteLine(translation);

            }
        }
    }
}

Now we are done with the code changes, Press F5 to run the Application, You can able to see the Console window Type a word or sentence in the English language and choose the language code to which you want to translate the text, and then press Enter from your Key Board.

For example, I have entered the word “love” and then I have chosen “it”(Italian) and then pressed Enter and also I have entered a statement in English “God bless you” and then entered “it”(Italian), then pressed Enter from the Keyboard. Then I have entered “God bless you” and then entered “es” and then I have entered “love” and then “es” You can able to see I got the OutPut as below.

love
it
Amore
God Bless you
it
Dio ti benedica
God Bless you
es
Que dios te bendiga
love
es
Amor

You can see the Output as below
