powershell-3.0 - How Can I Silence this PowerShell Error?

Question

I have an If statement in my script checking if an AD Object already exists. However, none of these evaluations prevent the host from printing the undesired evaluation "Directory object not found."

!$(Get-ADObject -Identity $ImportedObject.DistinguishedName -ErrorAction SilentlyContinue)


[void](!$(Get-ADObject -Identity $ImportedObject.DistinguishedName))


!$($(Get-ADObject -Identity $ImportedObject.DistinguishedName) | Out-Null)


$ErrorAction = $CurrentErrorAction
$ErrorAction = "SilentlyContinue"
!$(Get-ADObject -Identity $ImportedObject.DistinguishedName)
$ErrorAction = $CurrentErrorAction

Answer 1

尝试使用try{} ... catch{}这样的块

try 
{
// your code to find AD group goes here
}
  catch  {
      //whatever you want to do further
     }

另一种方法是使用命令行-Filter选项Get-ADUser
