サンプルコード

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Security.Cryptography;
using System.Windows.Forms;
using System.Drawing;
using LitJson;
using System.Net;
using System.Net.Http;

class form1: Form {
	private TextBox textBox1;
	private TextBox textBox2;
	form1() {
		Text = "virustotal";
		ClientSize = new Size(300, 400);
		Button btn1 = new Button();
		btn1.Location = new Point(150, 150);
		btn1.Text = "send";
		btn1.Click += btn1_Click;
		textBox1 = new TextBox();
		textBox1.Location = new System.Drawing.Point(30, 30);
		textBox1.Multiline = true;
		textBox1.Size = new System.Drawing.Size(250, 50);
		textBox1.TabIndex = 2;
		textBox1.Text = "52d3df0ed60c46f336c131bf2ca454f73bafdc4b04dfa2aea80746f5ba9e6d1c";
		textBox2 = new TextBox();
		textBox2.Location = new System.Drawing.Point(30, 230);
		textBox2.Multiline = true;
		textBox2.Size = new System.Drawing.Size(250, 50);
		textBox2.TabIndex = 2;
		Controls.AddRange(new Control[] {
			btn1,
			textBox1,
			textBox2
		});
	}
	void btn1_Click(object sender, System.EventArgs e) {
		ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
		string url = "https://www.virustotal.com/vtapi/v2/file/report?apikey=******&resource=" + textBox1.Text;
		HttpClient client = new HttpClient();
		string response = client.GetStringAsync(url).Result;
		LitJson.JsonData json = LitJson.JsonMapper.ToObject(response);
		Console.WriteLine("total: " + json["total"]);
		Console.WriteLine("positive: " + json["positives"]);
		textBox2.Text = json["positives"] + " / " + json["total"];
	}
	[STAThread]
	public static void Main() {
		Application.Run(new form1());
	}
}

以上。
