How to run IIS apppool recycle from powershell?

Question

I want to run the apppool recycle from a ps1 file using this:

#****** Variables
[String] $AppPoolName = $Global:Params['IIS_App_Pool_Name'] 
#$AppPoolName Contains the correct App Pool value from my IIS

[String] $WD=[System.Environment]::ExpandEnvironmentVariables("%WINDIR%")
[String] $appcmd = "$WD\system32\inetsrv\appcmd.exe"
&$appcmd list APPPOOL

iex $appcmd recycle apppool $AppPoolName

But i got this error:

A positional parameter cannot be found that accepts argument 'recycle'.

非常接近，您只需要引用传递给iex的整个字符串，否则它将尝试解析$appcmd之后的任何内容作为参数：

iex "$appcmd recycle apppool $AppPoolName"
