Maybe uploading the text to Google Translate and getting the language they think the text is in.

I made a translation program, that translates to many languages the user chooses at the same time, but it must predict the language of the source text.

What I have tried:

I used this

Google Translator[^]

To translate, I want something similar that downloads the prediction of the source language instead...

You want to look at a block of text and be able to identify the language???

I want please a C# code that uploads a string of text and receives the string of the name of the language from Google Translate.

If you have (or create) a translation program you should have dictionaries. Then count the number of known words from the text for each dictionary. While this would took some time it should give you the probabilities.

Solution 2

You can use the Google Translate API to do that - i.e. I mean specifically just detect/predict the source language not just the bit that does the translation
Detecting Languages | Google Cloud Translation API Documentation | Google Cloud Platform[^]

There is a similar API here - beware there is a charging structure in place for more than 5000 requests per day or more than 1Mb per day (which can soon add up if there is a lot of text!) - Language Detection API[^]

Jochen Arndt @User-2223753 has come up with another potential (manual) solution and there are more suggestions here - Language identification - Wikipedia[^]

If you need more suggestions then try using "Natural Language Processing" as a search term.

We don't write code for you. Both of the links to API's I gave you provide both examples of use and support.
Don't continue to learn by trial and error - invest in a good book or series of tutorials - there are several suggestions here on CodeProject to help you

i tried but get an error:

string getHTML(string url)
{
using (WebClient wc = new WebClient())
{
return wc.DownloadString(url);
}
}
MessageBox.Show(getHTML(@"https://translation.googleapis.com/language/translate/v2/detect?key=YOUR_API_KEY&q=Google%20Translate%20Rocks"));

if you go to this page: Translate API Client Library for .NET | API Client Library for .NET | Google Developers[^], it has a downloadable Google-build API library + a link to sample C# code... all found from the links provided above... You just need to take the time and look.

Graeme_Grant 14-Mar-17 12:00pm

5ed! :)

john1990_1 14-Mar-17 12:10pm

please take it easy on me since i learned C# by trial and error and know no other language, read the last comment

Graeme_Grant 14-Mar-17 12:22pm

Well done teaching yourself... I have also taught myself to program. :)

He is by pointing you in the right direction. If you had taken the time to look at the Google Translate API, you would have found this page: Detecting Languages | Google Cloud Translation API Documentation | Google Cloud Platform[^] (as I just did).

john1990_1 14-Mar-17 15:29pm

what is:
YOUR_API_KEY
?

john1990_1 14-Mar-17 15:36pm

{ "error": {
"code": 403,
"message": "The request is missing a valid API key.",
"errors": [
{
"message": "The request is missing a valid API key.",
"domain": "global",
"reason": "forbidden"
}
],
"status": "PERMISSION_DENIED"
}
}

You need to use the proper support facilities for the service you have chosen (I'm guessing it's the Google one)

Graeme_Grant 14-Mar-17 20:25pm

I gather that you did not get an API key ... The getting started page has that information for you: Quickstart | Google Cloud Translation API Documentation | Google Cloud Platform[^]

john1990_1 15-Mar-17 6:18am

Sorry the links you are giving are way too complex for me, how do I generate the API Key for my C# Forms app?

Graeme_Grant 15-Mar-17 6:20am

It is the simplest solution for what you want to do.

john1990_1 15-Mar-17 6:26am

is there a Youttube video you could please link to?

CHill60 15-Mar-17 6:28am

Have you tried searching for one yourself?

Graeme_Grant 15-Mar-17 6:32am

Jinx :P

john1990_1 15-Mar-17 6:49am

yes and i found irrelevant videos...

CHill60 15-Mar-17 6:54am

Well if you couldn't find one what makes you think we can? There probably isn't one - probably because the documentation on the links that Graeme supplied is so good.
