Receives from where and displays on what?

I'm sorry.

Receive a JSON data from a web application (I have a URL access).

In fact, the mission is to receive data from a web application in a desktop application by intermediate a web service, so now, I am in the web service and I am looking to write a function that receive the JSON data.

I hope that my idea is clear now and.
Thank you in advance

You wrote: 'from a web application (I have a URL access)' - do you mean a web-service?

No, what I meant to say that the JSON data come from a web application, and I want to write a function in a web service to retrieve this data.
I say a URL to access, ie these data will be sent as JSON from this URL.
exemple for URL (http://localhost:8081/xxxxx/case_types/load_all)

If I got you right you need no any intermediate web service.
You can use WebClient[^] class to download the JSON directly from the given URL...
Use WebClient.DownloadData(), than convert the resulting byte array to string and use it!

But the function from this class returns me the data in bytes, I tried to convert their string, but unfortunately I have not received the data provided

Excuse me, but it gives me in the header of the page
"This XML File does not APPEAR to have any style information Associated with it. The document tree is shown below"
and writing the tag in XML !

The date is :
{"id":"1","name":"Civil","litigation":"yes","corporate":"yes"},{"id":"2","name":"Criminal","litigation":"yes","corporate":"yes"}, ...

The code is :
string jsonData = "";
WebClient wc = new WebClient();
jsonData = wc.DownloadData("http://localhost:8081/xxxx/case_types/load_all");
jsonData = System.Text.Encoding.UTF8.GetString(buffer);
return jsonData;

When you open that URL in a browser what do you get?

Member 10872485 2-Jul-14 1:33am

it gives me the data in this form :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>App4Legal</title> <base href="http://localhost:8081/app4legal.v4.2.4/" /> <meta http-equiv="X-UA-Compatible" content="IE=Edge" /> <link rel="shortcut icon" type="image/x-icon"...

under title :
This XML file does not appear to have any style information associated with it. The document tree is shown below.

So? DownloadData will give you the very same. You have to extract from it the real value you want...
