Webb9 dec. 2024 · PowerShell supports arrays of one or more dimensions with each dimension having zero or more elements. Within a dimension, elements are numbered in ascending integer order starting at zero. Any individual element can be accessed via the array subscript operator [] ( §7.1.4 ). The number of dimensions in an array is called its rank.
