检测IIS网站已暂停

Question

I am currently able to detect whether a IIS Website is started/paused/stopped using the following code:

public int GetWebsiteStatus(string machineName, int websiteId)
{
    DirectoryEntry root = new DirectoryEntry(
        String.Format("IIS://{0}/W3SVC/{1}", machineName, websiteId));
    PropertyValueCollection pvc = root.Properties["ServerState"];
    return pvc.Value
    // - 2: Website Started
    // - 4: Website Stopped
    // - 6: Website Paused
}

I also want to detect if a Website is suspended or not. If the Website is suspended the method above still returns 2 (which is correct) but not enough for me.

I cannot find any code which do the job for IIS6 and higher.

Ah, do you mean the App Pool as stopped because of the timeout configuration? This is a different state to the web site remember? Well, certainly, you could change the settings so it doesn't recycle, but you could also try using code like this;

First, add a reference to \\Windows\\System32\\inetsrv\\Microsoft.Web.Administration.dll, then;

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Web.Administration;
namespace MSWebAdmin_Application
{
    class Program
    {
        static void Main(string[] args)
        {
            ServerManager serverManager = new ServerManager();
            Site site = serverManager.Sites["Default Web Site"];

            // get the app for this site
            var appName = site.Applications[0].ApplicationPoolName;
            ApplicationPool appPool = serverManager.ApplicationPools[appName];

            Console.WriteLine("Site state is : {0}", site.State);
            Console.WriteLine("App '{0}' state is : {1}", appName, appPool.State);

            if (appPool.State == ObjectState.Stopped)
            {
                // do something because the web site is "suspended"
            }
        }
    }
}

That code will independantly check the state of your appPool as opposed to your web site. It's possible for the web site to return "started" and the appPool to return "stopped".

See if it works in your case.

You might want to try using the following code, add your own logic and tidy up of course... but in essence you need to do the following and modify your code as you see fit.

Add the following enum

public enum ServerState
        {
            Unknown = 0,
            Starting = 1,
            Started = 2,
            Stopping = 3,
            Stopped = 4,
            Pausing = 5,
            Paused = 6,
            Continuing = 7
        }

Search for site and process it...

DirectoryEntry w3svc = new DirectoryEntry("IIS://" + "localhost" + "/W3SVC");
//check each site
foreach (DirectoryEntry site in w3svc.Children)
{
    foreach (var s in site.Properties)
    {
        try
        {
            ServerState state =
                (ServerState)
                Enum.Parse(typeof (ServerState), site.Properties["ServerState"].Value.ToString());

            if (state == ServerState.Paused)
            {
                //Do action
            }
        }
        catch (Exception)
        {

        }

    }
}

I hope this is useful for you as well...
