检测SQL Server重新启动

Question

My c# console app runs on an different machine than my SQL Server 2014. I use ado.net to connect to it. How can I detect if the sql server automatically reboots after installing windows updates? On my client application I use SystemEvents_SessionEnding but this does not help me.

I read about connection resiliency, but this seems also not to solve this problem.

Is there a specific ado.net event I can capture? Creating an app on the server sending UDP is not my prefered solution, aswell I dont want to use ping etc.

I'm really looking for something like an event to react on.

eg the notification services: https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlnotificationinfo(v=vs.110).aspx

Thanks!

If you want to see if the server is down or not you can use Ping Class.

using System.Net.NetworkInformation;

var ping = new Ping();
var reply = ping.Send("SqlServerIP");

if (reply.Status == IPStatus.Success)
{
    //server is available
}
else
{
    //server is down
}
