添加成員的奇怪行爲。獲得會員不返回任何值

Question

如果我寫了下面的代碼，就像你看到的，我使用Get-Member我得到一個空：

$UserToAdd = New-Object psobject 
$UserToAdd | Add-Member -membertype NoteProperty -Name "Name" -Value ([adsi]$_.path).name[0] 
$UserToAdd | Add-Member -membertype NoteProperty -Name "Email" -Value ([adsi]$_.path).mail[0] 
$UserToAdd | Add-Member -membertype NoteProperty -Name "DaysLeft" -Value $DaysTillExpiring 
$UserToAdd | Add-Member -membertype NoteProperty -Name "ExpirationTimestamp" -Value $ExpirationTimestamp.ToString("dd/MM/yyyy alle ore HH:mm:ss ") 
$UserToAdd | Add-Member -membertype NoteProperty -Name "SamAccountName" -Value ([adsi]$_.path).SamAccountName[0] 
$UserToAdd | get-member -Verbose 
get-content $UserToAdd 

但變量具有值，因爲當我使用類似get-content時，出現以下錯誤，包含正確的值：

get-content：找不到驅動器。名爲'@ {Name = XXXXXXXXX;電子郵件= XXXXXXXXXX; DaysLeft = 13; ExpirationTimestamp = 27/04/2014 alle ore 10'不存在。

我無法在PS 4.0上重現您的問題。一切正常後，你刪除了Get-Content部分，應該永遠不會在那裏擺在首位。

$UserToAdd = New-Object psobject 
$UserToAdd | Add-Member -membertype NoteProperty -Name "Name" -Value "hei" 
$UserToAdd | Add-Member -membertype NoteProperty -Name "Email" -Value "epost" 
$UserToAdd | Add-Member -membertype NoteProperty -Name "DaysLeft" -Value 3 
$UserToAdd | Add-Member -membertype NoteProperty -Name "ExpirationTimestamp" -Value ((date).ToString("dd/MM/yyyy alle ore HH:mm:ss ")) 
$UserToAdd | Add-Member -membertype NoteProperty -Name "SamAccountName" -Value "ops" 
$UserToAdd | get-member -Verbose 


    TypeName: System.Management.Automation.PSCustomObject 

Name    MemberType Definition              
----    ---------- ----------              
Equals    Method  bool Equals(System.Object obj)         
GetHashCode   Method  int GetHashCode()            
GetType    Method  type GetType()             
ToString   Method  string ToString()            
DaysLeft   NoteProperty System.Int32 DaysLeft=3           
Email    NoteProperty System.String Email=epost          
ExpirationTimestamp NoteProperty System.String ExpirationTimestamp=14.04.2014 alle ore 16:40:48 
Name    NoteProperty System.String Name=hei           
SamAccountName  NoteProperty System.String SamAccountName=ops 

如果Get-Member返回null，那麼你永遠不會創建擺在首位的對象，因爲即使沒有Add-Member線，Get-Member仍然會顯示此：

$UserToAdd = New-Object psobject 
$UserToAdd | get-member -Verbose
