如何在我的 PowerShell 脚本中将日期转换为 system.datetime 类型？

Question

I need to set -accountexpiration for multiple users in Active Directory using data from my CSV table with PowerShell. I have so far tried to do it with the command for a single user:

set-aduser -identity 'ABC' -accountexpirationdate 01/01/2020 

which works fine, but when I import the csv and use the assigned variable with foreach, it says:

Cannot convert value '01/01/2020' to type "system.datetime. Error: Sting was not recognized as a valid DateTime."

Suppose my table is as follows:

samaccountname,edate ABCD,01/01/2019 EFGH,02/02/2020

And I use the following script:

import-module activedirectory

$expirytable = import-csv 'c:\expire.csv'


foreach($user in $expirytable)

{

set-aduser -identity $expirytable.samaccountname -accountexpiration $expirytable.edate

}

I get:

Cannot convert value "01/01/2020" to type "system.Datetime". Error: "String was not recognized as a valid DateTime."

Answer 1

So here is what I was missing I figured out please compare my codes to find mistake.

import-module activedirectory

$expirytable = import-csv 'c:\expire.csv'

foreach($user in $expirytable)

{

$username = $user.samaccountname
$edate = $user.edate

set-aduser -identity $username -accountexpiration $edate

}
