The type operators always return a Boolean value, even if the input is a
collection of objects. However, when the input is a collection, the type
operators match the .NET Framework type of the collection. They do not
match the type of each object, even when all of the objects are of the same
type.
The Boolean type operators (-is and -isNot) always return a Boolean value,
even if the input is a collection of objects. The type operators always
operate on the input object as a whole. That is, if the input object is a
collection, it is the _collection_ type that is tested, not the types of the
collection's _elements_.

If the \<input> is a type that is _derived_ from the \[.NET Type\], `-is`
returns`$True`. If the \<input> is a type that is _derived_ from the \[.NET
Type\] `-as` converts the input to the target type. For
example, `(Get-Item /) -is [System.IO.FileSystemInfo]` returns `$True`,
because the type of the input, `[System.IO.DirectoryInfo]`, is _derived_ from
the `[System.IO.FileSystemInfo]`.

To find the .NET Framework type of an object, use the Get-Member cmdlet.
Or, use the GetType method of all the objects together with the FullName
