Powershell 脚本默认值未显示在 Get-Help -full 中

Question

我正在尝试设置我的 PowerShell 命令，所以 Get-Help -full将显示有关如何运行我的脚本的完整信息。我有要在此帮助中显示的默认值。我有以下几点:

<#
    .PARAMETER SenderEmail
    The name of the user who is sending the email message. Although not
    officially required, it will be checked to make sure it's not blank.
#>

Param (

   [String]
   [Parameter(
        Position=1,
        HelpMessage="Sender's Email Address")]
   $SenderEmail = "bob@fubar.com"
)

然而，当我输入 Get-Help -detail 时，会出现以下内容。

-SenderEmail <String>
    The name of the user who is sending the email message. Although not
    officially required, it will be checked to make sure it's not blank.

    Required?                    false
    Position?                    2
    Default value
    Accept pipeline input?       false
    Accept wildcard characters?

如何获得帮助以显示此参数的默认值？

Answer 1

我认为您无法获得默认值以在 V2 的高级功能中显示。我什至试过 [System.ComponentModel.DefaultValueAttribute("")] 没有运气。但是，如果有任何安慰的话，这在 V3 中似乎可以正常工作。

V3 ONLY!!
