从函数返回的数组附加了一个意外元素，我不知道如何修复它。非常感谢您的帮助。
由于未知原因，函数A中的数组与调用函数A的函数B中的数组不同。
function functionA(...)
{
[...]
$status = (,@("reserved",$proj,$id));
Write-Host "Status in FunctionA to FunctionB: "$status
[...]
return $status
}
我来自上面的
Write-Host：Status in FunctionA to FunctionB: reserved B hfuhfkhec8u8b7hf4smeu43gn4
function functionB(...)
{
[...]
$funcA = functionA
Write-Host "Status in FunctionB from FunctionA: "$funcA
[...]
}
我来自上面的
Write-Host：Status in FunctionB from FunctionA: 1 reserved B hfuhfkhec8u8b7hf4smeu43gn4。您可以观察到$status中的functionA没有值1，那么为什么我将值1附加在数组中呢？我该怎么解决？
请检查以下完整代码，其中FunctionA是CheckReservation，而FunctionB是PeriodicCheckIn
PS：我注意到，如果我将函数InformationMsgBox注释为在CheckReservation中不调用，则代码可以正常工作。
function CheckReservation($headers){
$events = GetCalendarEvents($headers)
$users = Get-IniFile ..\ini\Users.ini
$user = $users.$env:UserName.email
$error = "There is not any confirmed reservation for this machine."; $status = (,@("NoReservations",$error));

$calendarId = $calendarId.$env:Computername.calendarId
foreach($item in $events.items)
{
if($item.status -match "confirmed")
{

Where-Object {$_ -contains $user}
$calendar = $item.attendees |
Where-Object {$_.email -contains $calendarId}

答案 0 :(得分：1)
您已经注意到自己，应该InformationMsgBox来指责。每个返回输出的命令都会添加到管道中。
return $sh.Popup($msg,$msg_timeout,$global:AppTitle,1+64)返回您看到添加到数组中的1。您可以通过将其发送到Out-Null来抑制它的输出。
function InformationMsgBox($msg, $msg_timeout){
$sh = New-Object -ComObject "Wscript.Shell"
return $sh.Popup($msg,$msg_timeout,$global:AppTitle,1+64) | Out-Null
}
