应用场景：IIS网站挂掉，系统自动重启IIS，通知相关联系人；

主要代码：

监控类

public class monitoringiis
    {
        EmailSend send = new EmailSend();
        public void MonitoringISSAppPool(object obj)
        {
            string method_Start = "Start";
            string ISSAppPoolName = "";
            string iislist = System.Configuration.ConfigurationManager.AppSettings["iislist"];
            DirectoryEntry appPool = new DirectoryEntry("IIS://LOCALHOST/W3SVC/AppPools");
            while (true)
            {
                try
                {
                    foreach (DirectoryEntry item in appPool.Children)
                    {
                        string AppPoolCommand = item.Properties["ManagedPipelineMode"].Value.ToString();
