Why getting error on the ''Length" thing

[Droritos]

getting this error on unity:

“Assets\Scripts\AudioPlayer.cs(25,58): error CS1061: ‘Object’ does not contain a definition for ‘Length’ and no accessible extension method ‘Length’ accepting a first argument of type ‘Object’ could be found (are you missing a using directive or an assembly reference?)”

can’t figure the problem

Never mind found the problem

its supposed to be “Objects”
and not ‘‘Object’’

took me a while to figure it
