Calling Google AJAX Language API in C# .NET

 

Calling AJAX Language API from Non-Javascript environments, the API exposes a simple RESTful interface. In all cases, the method supported is GET and the response format is a JSON encoded result with embedded status codes. Details here.

Example in javascript. 

google.language.translate(“Hello world”, “”, “it”, function(result) {
if (!result.error) {
var container = document.getElementById(“translation”);
    container.innerHTML = result.translation;
}
});

And now the same code in C#:

WebRequest request = WebRequest.Create(“http://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=hello%20world&langpair=%7Cit”);

// This command performs a Language Translation(/ajax/services/language/translate), for Hello World (q=hello%20world)

// from English to Italian (langpair=en%7Cit).  i.e. en|it  . Or you can leave the source language blank if you want auto-detection & translation.

WebResponse response = request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
string json = reader.ReadLine();

JsonObject account;
JsonObject responseData;
JsonString responseDetails;
JsonNumber responseStatus;

using (JsonParser parser = new JsonParser(new StringReader(json), true))
    account = parser.ParseObject();

//responseDetails = (JsonString)account["responseDetails"];
responseStatus = (JsonNumber)account["responseStatus"];
responseData = (JsonObject)account["responseData"];

Console.WriteLine(“responseStatus: {0}”, responseStatus.Value);
Console.WriteLine(“translatedText: {0}”, responseData["translatedText"]);
Console.WriteLine(“detectedSourceLanguage: {0}”, responseData["detectedSourceLanguage"]);

// You can get the JSON .NET 2.0 parser I use from here.

// Or if you have .NET 3.5 you can use DataContractJsonSerializer to serializes objects to the JavaScript Object Notation (JSON) and deserializes JSON data to objects.
