Append an Array to an Array of Arrays in PowerShell
It's a common gotcha, arrays (and other collections) may get unrolled "unexpectedly". Use the comma operator (it makes/enforces an array with a single item and avoids unrolling):
$array1 = "11","12","13"$array2 = "21","22","23"$array3 = "31","32","33"$arrayAll = $array1, $array2, $array3$arrayAll.Count # returns 3$arrayAll = @()$arrayAll += , $array1$arrayAll += , $array2$arrayAll += , $array3$arrayAll.count # returns 3$arrayAll[1] # gets "21","22","23", i.e. $array2
Not sure I undestand what you are looking for, but it can help.
PS> $arrayAll = New-Object int[][] (3,3)PS> $arrayAll[0] = $array1PS> $arrayAll[1] = $array2PS> $arrayAll[2] = $array3PS> $arrayAll.Count3PS> $arrayAll[1][2]23It's a way to code an array of array.
Here is a way to code an array of two dimensions
PS> $arrayAll = New-Object 'int[,]' (3,3)PS> $arrayAll[2,0] = 12
