如何将多个字符串参数传递给PowerShell脚本？

顺便说一句，使用PowerShell的此处字符串也可以使您的函数更易于阅读，因为您无需将所有"-mark 都加倍：

function CreateAppPoolScript([string]$AppPoolName, [string]$AppPoolUser, [string]$AppPoolPass)
{
  # Command to create an IIS application pool
  return @"
cscript adsutil.vbs CREATE "w3svc/AppPools/$AppPoolName" IIsApplicationPool
cscript adsutil.vbs SET "w3svc/AppPools/$AppPoolName/WamUserName" "$AppPoolUser"
cscript adsutil.vbs SET "w3svc/AppPools/$AppPoolName/WamUserPass" "$AppPoolPass"
cscript adsutil.vbs SET "w3svc/AppPools/$AppPoolName/AppPoolIdentityType" 3
"@
}
