cmd.exe powershell哈希表

当使用cmd.exe调用时，PowerShell中是否有方法将哈希表作为参数传递

我想调用如下脚本：

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

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

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

---

其中arg4是哈希表。这可能吗

唯一想到的是将哈希表保存为xml，并将文件名传递给它。

给定如下脚本（foo.ps1）：

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

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，例如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
