Restarting a website from its own webpage.

Question

Well, just to keep it simple: I have a webform. On it a button called "Restart". I click on this button and IIS will restart itself.

Now, what would be the C# code that I would need to write behind the OnClick event of this web button? (If it's even possible?)

---

Then a second button is added. It's called "Reset" and should just reset the AppDomain for the current web application. What would be the code for this?

Answer 1

protected void Reload_Click(object sender, EventArgs e)
{
    HttpRuntime.UnloadAppDomain();
}

protected void Restart_Click(object sender, EventArgs e)
{
    using (var sc = new System.ServiceProcess.ServiceController("IISAdmin"))
    {
        sc.Stop();
        sc.Start();
    }
}

string processName = "aspnet_wp";

System.OperatingSystem os = System.Environment.OSVersion;

//Longhorn and Windows Server 2003 use w3wp.exe
if((os.Version.Major == 5 && os.Version.Minor > 1) || os.Version.Major ==6)
   processName = "w3wp";

foreach(Process process in Process.GetProcessesByName(processName))
   {
      Response.Write("Killing ASP.NET worker process (Process ID:" +
      process.Id + ")");
      process.Kill();
   }

Process iisreset = new Process();
iisreset.StartInfo.FileName   = "iisreset.exe";
iisreset.StartInfo.Arguments = "computer name";
iisreset.Start();

//iisreset.exe is located in the windows\system32 folder.

Answer 4

Is there more than one web site hosted on the server where this code will run? If so, you may want to look at the System.DirectoryServices namespace, and restart the individual web site
