Problem: elements of a System.Array couldn’t be counted
# Example output when an object is a Hashtable type
PS C:\Users\tola> $arr.gettype()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Hashtable System.Object
Resolution: convert a Hashtable to an Array type
# Perform explicit casting
PS C:\Users\tola> $x=[Array]$arr
# Example output when an object is an Array type
PS C:\Users\tola> $arr.gettype()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Object[] System.Array
# Validate that the casting has succeeded
PS C:\Users\tola> $x.gettype()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Object[] System.Array
# Since System Array type can contain objects, its elements can be counted
PS C:\Users\tola> $x.count
