How can I determine if a .NET assembly was built for x86 or x64?

Question

I\'ve got an arbitrary list of .NET assemblies.

I need to programmatically check if each DLL was built for x86 (as opposed to x64 or Any CPU). Is this possible?

cfeduke notes the possibility of calling GetPEKind. It's potentially interesting to do this from PowerShell.

Here, for example, is code for a cmdlet that could be used: https://stackoverflow.com/a/16181743/64257

Alternatively, at https://stackoverflow.com/a/4719567/64257 it is noted that "there's also the Get-PEHeader cmdlet in the PowerShell Community Extensions that can be used to test for executable images."
