👀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
