Powershell Beginner Question: Quick way to get value of an object property?

Hello.

I am new to Windows Powershell and am trying to learn it.

I am trying to understand how to quick get the values of object properties. For example, I am working in a directory with multiple text files. I can run the following to view the "IsReadOnly" property of one of the text files:

Get-ChildItem .\test1.txt | ForEach-Object {$_.IsReadOnly}

This works fine, but I would think that I could simply type the following and have Powershell return the value within:

test1.txt.IsReadOnly

This format of Object.Property doesn't seem to work. Am I missing something or is my only option to first select the object using "Get-ChildItem" and then pipe the object?

Thanks for your help! I'm looking forward to learning more of this stuff.
