cmd.exe powershell HashTable

Question

在使用cmd.exe调用时,PowerShell中是否有一种方法可以将HashTable作为参数传递？

我想调用这样的脚本:

powershell "& 'C:\path\to\file.ps1 arg1 arg2 arg3 arg4'"

其中arg4是HashTable.这可能吗？

Answer 1

给出一个像这样的脚本(foo.ps1):

param($a1, $a2, $a3, [hashtable]$a4)

"a1 is $a1"
"a2 is $a2"
"a3 is $a3"
"a4 is "
$a4

您可以从cmd.exe调用它,如此指定哈希表作为第四个参数:

C:\> powershell -command "& {c:\foo.ps1 1 2 three @{name='John';age=45}}"
a1 is 1
a2 is 2
a3 is three
a4 is

Name                           Value
----                           -----
name                           John
age                            45
