extract a string from this @{Name=WEBHOST001-OI3w}

You're seeing this output because $vcentername is not an object with a Name property — it's a string that only looks like @{Name=...}. That's why $vcentername.Name returns nothing.

If the value is literally:

$vcentername = '@{Name=WEBHOST001-OI3w}';

then $vcentername is just a plain string:

@{Name=WEBHOST001-OI3w}

You can extract the actual name like this:

($vcentername.Split("=")[1]).TrimEnd("}")

which returns:

WEBHOST001-OI3w

To help you get the cleanest solution, could you show the command that produces $vcentername?

If the source returns a real object, you won’t need to parse anything.
