如何在此Powershell代码中将字符串转换为布尔值以进行Exchange Online? [英] How to convert string to boolean in this Powershell code for Exchange Online?

问题描述

我的代码是:

Import-Csv "$env:userprofile\Desktop\ExternalContacts.csv"| foreach {New-MailContact -Name $_.Name -DisplayName $_.Name -ExternalEmailAddress $_.ExternalEmailAddress -FirstName $_.FirstName -LastName $_.LastName | Set-MailContact -Identity $_.Name -HiddenFromAddressListsEnabled $_.HiddenFromAddressListsEnabled}

我得到了:

无法在参数'HiddenFromAddressListsEnabled'上处理参数转换.无法将值"System.String"转换为类型"System.Boolean"，此类型的参数仅接受布尔值或数字，而应使用$ true，$ false，1或0.

Cannot process argument transformation on parameter 'HiddenFromAddressListsEnabled'. Cannot convert value "System.String" to type "System.Boolean", parameters of this type only accept booleans or numbers, use $true, $false, 1 or 0 instead.

这是在记事本中查看的CSV文件的前两行:

Here are the first two rows of my CSV file as viewed in Notepad:

Name,FirstName,LastName,ExternalEmailAddress,HiddenFromAddressListsEnabled
Ted Testington,Ted,Testington,[e-mail],$true

如何进行必要的转换?

谢谢.

推荐答案

使用-as时要小心.仅当字符串为0或1时有效.

Be careful with -as. It only works when a string is 0 or 1.

("FALSE") -as [bool]和[bool]("FALSE")都将返回True！

最好使用

[System.Convert]::ToBoolean("FALSE")
[System.Convert]::ToBoolean("False")
[System.Convert]::ToBoolean(0)

或解析

[bool]::Parse("FALSE")
[bool]::TryParse("FALSE", $outputVariable) # Will not raise an exception if the parse fails

Parse仅将字符串作为参数使用.

Parse only works with strings as parameter.
