Get all the names of the applications in a site

Question

I am trying to write a powershell script which gets the names of each application in a website in IIS in order to change the app pool associated with it. I am able to get the website, but I don't see a clear way to fetch each of the names?

Eg. I want to loop through them all: Api, Services, etc.. and then use

Set-ItemProperty "IIS:\Sites\RootSite\$loopedValue" -Name 'applicationPool' -Value $NewPool

I'm trying this:

Get-WebApplication -Site 'ABC'

Name             Application pool   Protocols    Physical Path                                                                                                        
----             ----------------   ---------    -------------                                                                                                        
Api              ABC                http         C:\Api
Services         ABC                http         C:\Services
Director         ABC                http         C:\Director
ReportingServer  ABC                http         C:\ReportingServer

But there is no way to get the Name from the members of Get-WebApplication.

Get-WebApplication | Get-Member

I don't really want to parse a string value from the path or PhysicalPath to do this. Is there another way?

Answer 1

An alternative way I came up with was to join the two results from Get-WebSite and Get-WebApplication

(get-website | select-object @{n='Site'; e={$_.Name}},@{n='Location'; e={$_.PhysicalPath}}) + (get-webapplication | select-object @{n='Site'; e= {$_.GetParentElement().Attributes['name'].value + $_.path }},@{n='Location'; e= {$_.PhysicalPath}})

Output:

Site                          WebType        Location
----                          -------        --------

Tu***.********.**.****App/api WebApplication C:\Web\Tu***.********.**.****vate

Answer 2

The following will provide the application names for all sites:

(Get-ChildItem -Path 'IIS:\Sites' -Recurse | Where-Object {$_.NodeType -eq 'application'}).Name

The following will return the application names for Default Web Site:

(Get-ChildItem -Path 'IIS:\Sites\Default Web Site' | Where-Object {$_.NodeType -eq 'application'}).Name
