Hi,

Either using the proper management classes such as https://docs.microsoft.com/en-us/dotnet/api/microsoft.web.administration.applicationpool?view=iis-dotnet (may require extra permissions ?) or indirectly by doing something triggering the restart.

If I ever do that it would be rather in a separate application rather then embedded into the app itself.

You can use WMI methods ApplicationPool.Stop and ApplicationPool.Start (calling them one after another) to restart the app pool

Also you could use the ServerManager Class (Microsoft.Web.Administration) which is very easy to use

protected void btnRestartAppPool_Click(object sender, EventArgs e)
{
      var manager = new ServerManager();
      var appPool = manager.ApplicationPools["Your_AppPool_Name"];            
      appPool.Stop();
      appPool.Start();
}

P.S. don't forget to install Microsoft.Web.Administration from the NuGet (right-click the project and select Manage NuGet Packages from the context menu) and then add the using directive for Microsoft.Web.Administration. Voila!

hello

how to check is that code is working or not 

sp_configure can show result or have to see other ways

for older version how would be this var

var appPool = manager.ApplicationPools["Your_AppPool_Name"];

Buddy you don't even try to do something by yourself. Please be aware that this is not a place where we write code for you. Rather, we provide help after you have given your best. Have you?

OK I cannot guarantee that the following will work as I am not sure if the wanted  attribute name is correct (You may want to google the attributes list). Anyway here we go

ServerManager manager = new ServerManager();
var appPool = manager.ApplicationPools["Your_AppPool_Name"];
if(appPool != null)
{
    if(appPool.State == ObjectState.Started)
    {
         // latest recycle time
         Response.Write(appPool.GetAttribute("StartTime").Value + "<br />");

         appPool.Stop();
         appPool.Start();

         // minutes since the last recycle (should be zero if the code works)
         Response.Write(appPool.Recycling.PeriodicRestart.Time.TotalMinutes);
    }                
}

Hi Gopi.MCA,

You can also try use ApplicationPool.Recycle Method to restart application pool. 

Note: You need to publish your application to iis, and then test.

 ServerManager serverManager = new ServerManager();
            ApplicationPool appPool = serverManager.ApplicationPools["applicationpool name"];
            if (appPool != null)
            {
                if (appPool.State == ObjectState.Stopped)
                {
                    appPool.Start();
                }
                else
                {
                    appPool.Recycle();
                }
            }

Best regards,
