Creating a Language Translator with C#

C# can be used to create language translation applications by leveraging translation services like the Microsoft Translator Text API. In this example, we'll demonstrate how to translate text from one language to another.

Sample C# Code for Language Translation

Here's a basic example of C# code that translates text using the Microsoft Translator Text API. Please replace `'YOUR_API_KEY'` with your actual API key obtained from the Azure portal:

using System;
using System.Net.Http;
using System.Threading.Tasks;
class LanguageTranslator
private const string apiKey = "YOUR_API_KEY";
private const string endpoint = "";
private const string route = "/translate?api-version=3.0&to=en"; // Translate to English
public static async Task<string> TranslateTextAsync(string text)
using (var client = new HttpClient())
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", apiKey);
var requestBody = new object[] { new { Text = text } };
var content = new StringContent(requestBody.ToString(), System.Text.Encoding.UTF8, "application/json");
var response = await client.PostAsync(endpoint + route, content);
var responseBody = await response.Content.ReadAsStringAsync();
return responseBody;
class Program
static async Task Main()
string textToTranslate = "Hello, world!"; // Text to translate
string translatedText = await LanguageTranslator.TranslateTextAsync(textToTranslate);
Console.WriteLine("Original Text: " + textToTranslate);
Console.WriteLine("Translated Text: " + translatedText);

This code demonstrates how to translate text from one language to another using the Microsoft Translator Text API. In a real application, you would handle multiple languages, user input, and a more user-friendly interface.
