Set Value of Nested Object Property by Name in PowerShell

I am traversing an object and would like to replace several path parts with a string stored in another variable. For example:
# a is a complex ps object, the path is valid
$a.b.c
myvalue
$replace = "b.c"
$a.$($replace)
# here I expect 'myvalue', however nothing is returned, as I would like to execute the equivalent of $a.b.c
Is there some way to do this replacement?

Powershell reevaluate string to array
(1 answer)
Closed 4 months ago.
I have a variable that stores a command that I would like to execute.
ex:
$C = "echo 'test'"
I have one way to execute this by using the following:
powershell .($C)
however this opens a new instance of powershell. How can I go about executing that code in the same instance? I can't seem to find a way to use dot sourcing without opening that second instance.
EDIT: I can not use IEX

Using a Variable (PowerShell) inside of a command

I have trouble with following piece of code:
$result = "F651F545A059588ABFDCE7EE3EEB27EED8CED28D"
winrm create winrm/config/Listener?Address=*+Transport=HTTPS '#{Hostname="my.host.winagent"; CertificateThumbprint="$result"}'
it yields:
Message = The WS-Management service cannot process the configuration request because the certificate thumbprint in the request is not a valid hex string: $result.
it looks like variable result is not being expanded, probably because it is inside array? How to get the variable value expanded there?
You need to use " (not ') to create an expandable string literal - escape the literal "'s by doubling them:
winrm create winrm/config/Listener?Address=*+Transport=HTTPS "#{Hostname=""my.host.winagent""; CertificateThumbprint=""$result""}"

Get only filename from full path of a file

I'm writing a PowerShell script to output the process,
$Process=chknull $_.Properties[0].Value
$Process_new=$Process -replace '(?<! .*) ','_'
The above code outputs the result as entire path of process, Eg:
C:\Windows\System32\Notepad.exe.
Is there a way, where I can get just "Notepad.exe"
If you're getting a full path return like that as a string you can set the value into a variable and then use split on it and grab the last entry in the resulting array.
Example:
("C:\Windows\System32\Notepad.exe." -split "\\")[-1]
Remember to use two "\" as it is also an escape character in regex.
([IO.FileInfo]"C:\Windows\System32\Notepad.exe").Name

Is a function call in a verbatim PowerShell string a thing?
CSharp example:
$"this my { GetSomeValue() }";
I would rather not extract a variable if I don't have to.
I always do it this way:
$verbatimString = 'something' + (GetSomeValue) + 'end'
Since it's verbatim string, you cannot do any trick, to put value directly into it, like you showed in your example.
