尝试如下所示:

start-job -filepath myscript.ps1 -arg (,$myarr)

-ArgumentList接受参数列表/数组.因此，当您提供-arg $myarr时，就好像您要传递数组的元素作为参数一样.因此，您必须强制PowerShell将其视为单个参数(即数组).

The -ArgumentList takes in a list/array of arguments. So when you give -arg $myarr, it is as though you are passing the elements of the array as the arguments. So you have to force PowerShell to treat it as a single argument which is an array.
