自动完成参数powershell的值

Question

我试图找到为可以自动完成的参数创建值的方法,或者使用tab显示所有可用选项,例如cmdlet中的值"allsigned"

Set-ExecutionPolicy -ExecutionPolicy AllSigned

¿有关如何在程序中调用它的任何想法或我如何实现这一点？

Answer 1

高级函数/ cmdlet或仅参数验证,参数集等

来自ISE的片段:

function Verb-Noun
{
    [CmdletBinding(DefaultParameterSetName='Parameter Set 1', 
                  SupportsShouldProcess=$true, 
                  PositionalBinding=$false,
                  HelpUri = 'http://www.microsoft.com/',
                  ConfirmImpact='Medium')]
    [Alias()]
    [OutputType([String])]
    Param
    (
        # Param1 help description
        [Parameter(Mandatory=$true, 
                   ValueFromPipeline=$true,
                   ValueFromPipelineByPropertyName=$true, 
                   ValueFromRemainingArguments=$false, 
                   Position=0,
                   ParameterSetName='Parameter Set 1')]
        [ValidateNotNull()]
        [ValidateNotNullOrEmpty()]
        [ValidateCount(0,5)]
        [ValidateSet("sun", "moon", "earth")]
        [Alias("p1")] 
        $Param1,

        # Param2 help description
        [Parameter(ParameterSetName='Parameter Set 1')]
        [AllowNull()]
        [AllowEmptyCollection()]
        [AllowEmptyString()]
        [ValidateScript({$true})]
        [ValidateRange(0,5)]
        [int]
        $Param2,

        # Param3 help description
        [Parameter(ParameterSetName='Another Parameter Set')]
        [ValidatePattern("[a-z]*")]
        [ValidateLength(0,15)]
        [String]
        $Param3
    )

    Begin
    {
    }
    Process
    {
        if ($pscmdlet.ShouldProcess("Target", "Operation"))
        {
        }
    }
    End
    {
    }
}

是的,它叫validateset

Param
      (
        [parameter(Mandatory=$true)]
        [ValidateSet("Low", "Average", "High")]
        [String[]]
        $Detail
      )
