.NET 检测地址/主机/域名是否正常

🌱PING 地址/主机名/域名

     /// <summary>
     /// PING
     /// </summary>
     /// <param name="ip">ip</param>
     /// <returns></returns>
     public static bool PingIp(string ip)
     {
         System.Net.NetworkInformation.Ping p = new System.Net.NetworkInformation.Ping();
         System.Net.NetworkInformation.PingOptions options = new System.Net.NetworkInformation.PingOptions();
         options.DontFragment = true;
         string data = "Test Data!";
         byte[] buffer = Encoding.ASCII.GetBytes(data);
         int timeout = 2000; // Timeout
         System.Net.NetworkInformation.PingReply reply = p.Send(ip, timeout, buffer, options);
         if (reply.Status == System.Net.NetworkInformation.IPStatus.Success)
         {
           //  AddToConvo(ip + reply.Status);
             return true;
         }
         else
         {
            // AddToConvo(ip + reply.Status);
             return false;
         }
     }

👀调用方法

  List<string> list = new List<string>();
  list.Add("192.168.1.1");
  list.Add("192.168.3.1");
  list.Add("192.168.4.1");

  foreach (string s in list)
  {
     Console.WriteLine(s+" "+ ccPing.PingIp(s));
        //if(!xxx) 
  }
  
  Thread.Sleep(10000);

📫检查URL

        public async Task<bool> IsServerRespondingAsync(string url, TimeSpan timeout)
        {
            try
            {
                using (var cancellationTokenSource = new System.Threading.CancellationTokenSource())
                {
                    cancellationTokenSource.CancelAfter(timeout);
                    var response = await _httpClient.GetAsync(url, cancellationTokenSource.Token);
                    return response.IsSuccessStatusCode;
                }
            }
            catch (TaskCanceledException)
            {
                // 请求超时
                return false;
            }
            catch (Exception)
            {
                // 发生其他错误
                return false;
            }
        }

⚡异步调用

 await checker.IsServerRespondingAsync(url, TimeSpan.FromSeconds(2));

如果False可以调用报警代码
