In PowerShell, How I do I filter for an object by its nested property key/value object?

Question

An object returned from a get-log command can look like

Date: <date>
Properties: 
        statusCode     : OK
        serviceRequestId: 97168d7a-4c92-4d65-b509-65785b14ef42
Name: <name>
Details: <details>

I want to do something that returns that the one object by doing something like

get-log | where-object { $_.Properties.serviceRequestId -eq '97168d7a-4c92-4d65-b509-65785b14ef42' }

Of course, this does not work, but I want something that works like this.

My goal is to see the "Details" property.

The filtering sample you provided works as is:

get-log | where-object { $_.Properties.serviceRequestId -eq '97168d7a-4c92-4d65-b509-65785b14ef42' }

That will return the object(s) you want (the full object, not just inner properties).

So you can use the result of that to get at any other property, like Details:

$result = get-log | where-object { $_.Properties.serviceRequestId -eq '97168d7a-4c92-4d65-b509-65785b14ef42' }
$result.Details

Or you can do it all in one line by continuing the pipeline and using Select-Object:

get-log | 
    where-object { 
        $_.Properties.serviceRequestId -eq '97168d7a-4c92-4d65-b509-65785b14ef42' 
    } |
    Select-Object -ExpandProperty Details

(did it on multiple lines for better readability)
