I want to recycle the application pool through my application.
Previously I was storing the application pool name in my database and using that to recycle.
But It happened in the past that we moved apps from one app pool to another and sometimes we forget to update the app pool name in the database.
So I am thinking to get the app pool name through the application and use that for recycling.
In many cases it might be enough to just read the name of the application pool from the environment variable:
var apppool = System.Environment.GetEnvironmentVariable(
"APP_POOL_ID", EnvironmentVariableTarget.Process);
Modified version of #Razon answer :)
public static string GetCurrentApplicationPoolName()
{
ServerManager manager = new ServerManager();
string DefaultSiteName = System.Web.Hosting.HostingEnvironment.ApplicationHost.GetSiteName();
Site defaultSite = manager.Sites[DefaultSiteName];
string appVirtualPath = HttpRuntime.AppDomainAppVirtualPath;
string appPoolName = string.Empty;
foreach (Application app in defaultSite.Applications)
{
string appPath = app.Path;
if (appPath == appVirtualPath)
{
appPoolName = app.ApplicationPoolName;
}
}
return appPoolName;
}
May this can help: ApplicationPoolName Property
Namespace: Microsoft.Web.Administration
Assembly: Microsoft.Web.Administration (in Microsoft.Web.Administration.dll)

I've created an application that gets all of my Sites in IIS and checking each URL in Bindings if there's an HTTP error and if a certain error is encountered, my application will reset the IIS Site Instance in IIS, however, it's not enough to fix the error as it should. I would be needing to reset both the Site and the Application pool it belongs to.
Is there any way to get the Application Pool object based on the Site object?
I have tried the code below but this only works if an application pool only has 1 Site/Application in it. The problem is, I don't get the matching App Pool of the Site if I have a number mismatch between the List of Sites vs List of ApplicationPools since 1 AppPool can have multiple Sites/Applications.
ServerManager serverMgr = new ServerManager();
SiteCollection sites;
ApplicationPoolCollection appPools;
public List<(Site, ApplicationPool, string)> getSiteInfo()
{
List<(Site, ApplicationPool, string)> siteInfo = new List<(Site, ApplicationPool, string)>();
List<string> siteUrls = new List<string>();
sites = serverMgr.Sites;
appPools = serverMgr.ApplicationPools;
foreach (Site site in sites)
{
foreach (ApplicationPool appPool in appPools)
{
foreach (Binding binding in site.Bindings)//getting site url
{
string bindingInfo = binding.BindingInformation; // "192.111.1.1:80:google.com" /// *:808:
string[] adrs = bindingInfo.Split(':'); //0 = ip, 1 = port, 2 = hostname
if (adrs[0] == "*")
{
adrs[0] = "localhost";
}
//adding to my list of sites and it's corresponding Application Pool in 1 tuple variable
siteInfo.Add((site, appPool, adrs[0] + ":" + adrs[1] + "/" + adrs[2])); //localhost:80/google.com
}
}
}
return siteInfo;
}
I need something similar to this code: (see comments)
public List<(Site, ApplicationPool, string)> getSiteInfo()
{
List<(Site, ApplicationPool, string)> siteInfo = new List<(Site, ApplicationPool, string)>();
List<string> siteUrls = new List<string>();
sites = serverMgr.Sites;
foreach (Site site in sites)
{
foreach (Binding binding in site.Bindings)
{
//I need something like this to make sure the AppPool I'm getting is of the Site I have.
ApplicationPool appPool = site.ApplicationPoolName;//<-- This Line
string bindingInfo = binding.BindingInformation;
string[] adrs = bindingInfo.Split(':');
if (adrs[0] == "*")
{
adrs[0] = "localhost";
}
//So that I can do this when passing the Site Info tuple Variable with the Site Object together with the corresponding AppPool for later use of the IISReset Class in my project.
siteInfo.Add((site, appPool, adrs[0] + ":" + adrs[1] + "/" + adrs[2]));
}
}
return siteInfo;
}
Sorry for the long and sloppy explanation but I would be happy to clear out if you have questions with this. Thank you.
I figured it out by using Applications attribute of a site. To get the application pool of a Site I did the code below. Where I got the list of applications of a site and used that to identify the app pool from the list of application pools in the server. However this only works if the site only has 1 application, that's why I'm indexing 0(zero) to get the first application (which is the only application of my site) to search for it's corresponding app pool.
ApplicationCollection apps = site.Applications;
ApplicationPool appPool = serverMgr.ApplicationPools[appname[0].ApplicationPoolName];
I'm running Windows Server 2012 with IIS 8. I have IIS 6 Metabase Compatibility installed. I have been trying to figure out how to change the App Pool Identity for IIS 8 with .Net 4.5 - all of the examples I found are for IIS 6 and 7.
Here is what I have:
public class InternetInformationServices
{
public void SetApplicationPoolIdentity(string appPoolName, string domain, string username, string password)
{
try
{
string metabasePath = "IIS://Localhost/W3SVC/AppPools";
DirectoryEntry myAppPool;
DirectoryEntry apppools = new DirectoryEntry(metabasePath);
myAppPool = apppools.Children.Find(appPoolName, "IIsApplicationPool");
myAppPool.Invoke("AppPoolIdentityType", new Object[] { 3 });
myAppPool.Invoke("WAMUserName", new Object[] { domain + #"\" + username });
myAppPool.Invoke("WAMUserPass", new Object[] { password });
myAppPool.Invoke("SetInfo", null);
myAppPool.CommitChanges();
}
catch (Exception)
{
throw;
}
}
}
The code is able to find the App Pool, but as soon as I invoke it to set any of the following:
myAppPool.Invoke("AppPoolIdentityType", new Object[] { 3 });
myAppPool.Invoke("WAMUserName", new Object[] { domain + #"\" + username });
myAppPool.Invoke("WAMUserPass", new Object[] { password });
I get the following error on the inner exception:
Value does not fall within the expected range.
I'm not sure what I'm missing, or what is different with IIS 8.
Here's a way to get this type of code snippet for most things in the iis metabase. we use this process to script automation at my office.
I'll use your question about specifying credentials as an example:
open inetmgr first and then select your hostname and then open the config.
then select the system.applicationHost/applicationPools config section and expand the app pools collection, when done exit the window:
select the appropriate application pool, change the identitytype to specific user and set the user and pass.
Now click on Generate script, do not apply changes.
FINALLY: All the api goodness you wanted, including your sample code:
Try this ( from How can I change the username/password of an ApplicationPool in IIS from C#? )
myAppPool .Properties["AppPoolIdentityType"].Value = 3;
myAppPool .Properties["WAMUserName"].Value = Environment.MachineName + #"\" + username;
myAppPool .Properties["WAMUserPass"].Value = password;
i'm trying to add an application to site via code (C#) and i get a null reference.
someone have an idea why?
here's the code i use:
Application app;
using (var sm = new ServerManager())
{
if (site.Applications["/" + appName] == null)
{
site.Applications.Add("/" + appName, physicalPath);
sm.CommitChanges();
}
app = site.Applications["/" + appName];
}
return app;
the code fails on the "add" line.
the appName is a string like "MyNewApp".
the physicalPath is a string like "C:\inetpub\wwwroot\MyService".
the site is Microsoft.Web.Administration.Site object of the IIS6.1 (win 7 ent) default web site.
found the answer: NullReferenceException in Microsoft.Web.Administration when adding https binding
its all because of the "using" statement.
the site didn't have a parent ServerManager at the point of the application add.
I'm using the following method to create application pool and assign it to web site.
This is code for application pool creation:
WebSiteName = some website name which existed.
I see that all values are get where they should be in debug mode
private void ConfiugreAppPoolIIS7(targetMachine)
{
var mgr = ServerManager.OpenRemote(targetMachine);
if (AppPoolProp.ContainsKey("SomeTestAppPool"))
{
string reqAppPool = AppPoolProp["SomeTestAppPool"];
if (!mgr.ApplicationPools.Any(pool => pool.Name == reqAppPool))
{
ApplicationPool myApp = mgr.ApplicationPools.Add(reqAppPool);
myApp.AutoStart = true;
myApp.ManagedPipelineMode = ManagedPipelineMode.Classic;
myApp.ManagedRuntimeVersion = "V4.0";
myApp.ProcessModel.IdentityType = ProcessModelIdentityType.NetworkService;
myApp.Enable32BitAppOnWin64 = true;
mgr.CommitChanges();
foreach (Site site in mgr.Sites)
{
if(site.Name == WebSiteName)
{
site.Stop();
site.ApplicationDefaults.ApplicationPoolName = myApp.Name;
site.Start();
mgr.CommitChanges();
}
}
}
}
}
The result is, I see the Aplication pool created successfuly, and the Website created as well, but, I see in the advanced settings of my web site the default appplication pool is assigned.
Could you please help?
The problem has been fixed by fixing reference to right Microsoft.Web.Administration.dll
Cause of this server manage connected to express iis instead of my local iis.
I have successfully automated the process of creating a new IIS website, however the code I've written doesn't care about application pools, it just gets added to DefaultAppPool. However I'd like to add this newly created site to an existing application pool.
Here is the code I'm using to create the new website.
var w3Svc = new DirectoryEntry(string.Format("IIS://{0}/w3svc", webserver));
var newsite = new object[] { serverComment, new object[] { serverBindings }, homeDirectory };
var websiteId = w3Svc.Invoke("CreateNewSite", newsite);
site.Invoke("Start", null);
site.CommitChanges();
<update>
Although this is not directly related to the question, here are some sample values being used above. This might help someone understand exactly what the code above is doing more easily.
webServer: "localhost"
serverComment: "testing.dev"
serverBindings: ":80:testing.dev"
homeDirectory: "c:\inetpub\wwwroot\testing\"
</update>
If I know the name of the application pool that I'd like this web site to be in, how can I find it and add this site to it?
You have to assign the AppPool on the virtual dir (not the webserver) and set the AppIsolated property to 2 which mean pooled-process ;)
http://msdn.microsoft.com/en-us/library/ms525598%28v=VS.90%29.aspx
Relevant code sample from link:
static void AssignVDirToAppPool(string metabasePath, string appPoolName)
{
// metabasePath is of the form "IIS://<servername>/W3SVC/<siteID>/Root[/<vDir>]"
// for example "IIS://localhost/W3SVC/1/Root/MyVDir"
// appPoolName is of the form "<name>", for example, "MyAppPool"
Console.WriteLine("\nAssigning application {0} to the application pool named {1}:", metabasePath, appPoolName);
try
{
DirectoryEntry vDir = new DirectoryEntry(metabasePath);
string className = vDir.SchemaClassName.ToString();
if (className.EndsWith("VirtualDir"))
{
object[] param = { 0, appPoolName, true };
vDir.Invoke("AppCreate3", param);
vDir.Properties["AppIsolated"][0] = "2";
Console.WriteLine(" Done.");
}
else
Console.WriteLine(" Failed in AssignVDirToAppPool; only virtual directories can be assigned to application pools");
}
catch (Exception ex)
{
Console.WriteLine("Failed in AssignVDirToAppPool with the following exception: \n{0}", ex.Message);
}
}
Note that if you are not explicitly adding a new virtual directory to the application, the metabasePath will simply be "IIS://<servername>/W3SVC/<siteID>/Root"
You need to get the AppPoolfrom IIS://{0}/W3SVC/AppPools, and attach it to the site's AppPoolId. Something like:
var appPool = new DirectoryEntry(
string.Format("IIS://{0}/W3SVC/AppPools/{1}", webServer, appPoolName)
);
site.Properties["AppPoolId"].Value = appPool;
site.Properties["AppPoolId"][0]= "poolname";
