Question

我在OS X上的DNX Core 5.0中遇到SendPingAsync问题。基本上我正在尝试构建一个基于MVC的小站点，该站点ping一系列IP地址10.0.0.1 - ＆gt; 10.0.0.254。我到目前为止的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNet.Mvc;
using System.Net;
using System.Net.NetworkInformation;

namespace PingTest1.Controllers
{
    public class HomeController : Controller
    {
        public static async Task<PingReply> sendPing(IPAddress ip)
        {
            var reply = await new Ping().SendPingAsync(ip, 1000);
            return reply;
        }

        public IActionResult Index()
        {
            Dictionary<string, string> ipas = new Dictionary<string, string>();

            for (int i = 1; i < 255; i++) {
                IPAddress ipa = new IPAddress(new byte[] {10, 0, 0, (byte)i});
                Task<PingReply> result = sendPing(ipa);
                ipas.Add("10.0.0." + i, result.Result.Status.ToString());
            }

            ViewData["ipas"] = ipas;

            return View();
        }

        public IActionResult Error()
        {
            return View();
        }
    }
}

因以下未被捕获的例外而失败：

An unhandled exception has occurred: Method not found: 'System.Threading.Tasks.Task`1<System.Net.NetworkInformation.PingReply> System.Net.NetworkInformation.Ping.SendPingAsync(System.Net.IPAddress, Int32)'.
      System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task`1<System.Net.NetworkInformation.PingReply> System.Net.NetworkInformation.Ping.SendPingAsync(System.Net.IPAddress, Int32)'.

我已将完整的源代码上传到GitHub：https://github.com/00101010b/PingTest1

作为C＃和ASP.net 5.0的完整菜鸟，我不知道我在做什么，所以任何帮助都会非常感激。
