PHPとVS2015をJSONで連携する。

using System.Net;

namespace GetJson
{
    public partial class Form1 : Form
    {
        private const string url = "https://zip358.com/tool/view-json/index.php";
        public Form1()
        {
            InitializeComponent();
        }

        private void button_Click(object sender, EventArgs e)
        {
            using (WebClient wc = new WebClient())
            {
                byte [] response = wc.DownloadData(url);
                string str = System.Text.Encoding.UTF8.GetString(response);
                richTextBox1.Text = str;
            }
        }
    }
}

<?php
$hoge = [];
$foo = 'jsonｷﾀ━(ﾟ∀ﾟ)━!name';
for ($i = 1; $i < 100; $i++){
    $hoge[] = ["id"=>$i,"name"=>$foo];
}   
header('Content-type: application/json;charset=UTF-8');
echo json_encode($hoge, JSON_UNESCAPED_UNICODE);
