Powershell脚本默认值未显示在Get-Help -full中

Question

我正在尝试设置PowerShell命令，因此Get-Help -full将会显示有关如何运行脚本的完整信息。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"
)

但是，当我键入Get-Help -detail时，将显示以下内容。

-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

我认为您无法在V2的高级功能中显示默认值。我什至没有运气就尝试过[System.ComponentModel.DefaultValueAttribute（“”）]。但是，如果有什么安慰的话，这似乎可以在V3中按原样工作。

V3 ONLY!!
