How to `select` to an array of strings

Question

When I use the Select-Object Name CmdLet it seems to create a new object with a single Name property on it.

I often want to pipe this selection to other CmdLets but they often take just a string.

How can I easily get a bunch of objects and say "Select only property x and just the property values into an array or collection of just its values"?

You can use the ExpandProperty parameter for this. This switch means that instead of returning an object with properties as listed on the (default) -Properties parameter, the value of the single property listed under -ExpandProperty parameter is returned.

NB: You can also use the alias, expand for this parameter.

Example:

Get-Process | Select-Object -ExpandProperty ProcessName

Not to badmouth SS64, but why would people link there instead of to the actual documentation?

@AnsgarWiechers fair point; edited to include your MS link. I always go for SS64 first since generally I find those explanations/examples clearer (personal preference).
