Hello, provide a sample code for displaying the status of an online or offline client.

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace App
    public partial class FormMain : Form
        public FormMain()
    //Here is the code for connecting to the client API and checking its status

Tell me what command to write to connect to the client API Thank you!

As a general rule of thumb, people aren’t going to write your projects for you for free.

If you are actually looking for guidance, here at some links which might help you:

One option is to use HttpClient or WebRequest to make the request, then Json.NET to deserialize the response. Alternatively, you can use a framework which makes this a bit easier, for example RestSharp.
