How to get the ApplicationPool object based on a Site in IIS

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];

Check out files from TFS from a web service

I've read several posts here about replacing the obsolete TeamFoundationServer with TfsTeamProjectCollectionFactory but not in a web service. The obsolete method works in my web service but the TfsTeamProjectCollectionFactory method does not. It always throws an exception setting the workspace variable:
There is no working folder mapping for C:\MyPath
The web service uses an app pool assigned to my identity which is a local machine admin and the new method works if I make it a console app.
Is it doable to replace TeamFoundationServer in a web service?
void TfsCheckout(string tfsServer, string wkSpace, string fileName)
{
try
{
//new method
var pc = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri(tfsServer));
var versionControlServer = (VersionControlServer)pc.GetService((typeof(VersionControlServer)));
var workspace = versionControlServer.GetWorkspace(wkSpace);
var result = workspace.PendEdit(fileName);
//obsolete method
var tfs = new TeamFoundationServer(tfsServer, new UICredentialsProvider());
var versionControl = (VersionControlServer)tfs.GetService(typeof(VersionControlServer));
var workspc = versionControl.GetWorkspace(Environment.MachineName, versionControl.AuthenticatedUser);
result = workspc.PendEdit(fileName);
UpdateStatus(new UpdateStatusEventArgs("Checkout: " + fileName));
UpdateStatus(new UpdateStatusEventArgs("Result: " + result + " (1=success 0=fail)"));
}
catch (Exception ex)
{
UpdateStatus(new UpdateStatusEventArgs(ex.ToString()));
UpdateStatus(new UpdateStatusEventArgs("Done"));
}
}

How can you get a website application name within a website?

I want to be able to check if an application exists within an existing website but I've not found anything. At the moment I have an installer project that gets the input from the user for the name of an existing website. I use this to check the site currently exists in IIS, and if so I then want to search the existing applications to see if a particular 1 exists. Here's what I have:
private void CheckWebsiteApps()
{
SiteCollection sites = null;
try
{
//Check website exists
sites = mgr.Sites;
foreach (Site s in sites)
{
if (!string.IsNullOrEmpty(s.Name))
{
if (string.Compare(s.Name, "mysite", true) == 0)
{
//Check if my app exists in the website
ApplicationCollection apps = s.Applications;
foreach (Microsoft.Web.Administration.Application app in apps)
{
//Want to do this
//if (app.Name == "MyApp")
//{
// Do Something
//}
}
}
}
}
}
catch
{
throw new InstallException("Can't determine if site already exists.");
}
}
Obviously app.Name doesn't exist, so what can I do to get this?

You can use the Microsoft.Web.Administration and Microsoft.Web.Management API for IIS to do this. They are not in the GAC though, you have to reference them from the inetsrv folder. On my machine they are located at...
C:\Windows\System32\inetsrv\Microsoft.Web.Administration.dll
C:\Windows\System32\inetsrv\Microsoft.Web.Management.dll
Here is some example code of enumerating them,
class Program
{
static void Main(string[] args)
{
ServerManager serverManager = new ServerManager();
foreach (var site in serverManager.Sites)
{
Console.WriteLine("Site -> " + site.Name);
foreach (var application in site.Applications)
{
Console.WriteLine(" Application-> " + application.Path);
}
}
Console.WriteLine("Press any key...");
Console.ReadKey(true);
}
}
Follow Up:
Applications do not have names, only the root Site has a name in IIS. Applications only have a path (as they are children of sites). If the Path is "/" then the Application is the root application for the site. If the path is anything other than / then it is a 2nd+ child application of the site. So you would need to use Application.Path to do what you want.

How to programmatically set App Pool Identity on IIS 8

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;

When programmatically creating a new IIS web site, how can I add it to an existing application pool?

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";
