您可以在没有 ValueFromRemainingArguments 的情况下声明它:
param(
[Parameter(
Position=0,
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true)]
[Alias('PSPath')]
[string[]]
$files,
$installdir,
$compilemode
)
然后使用逗号运算符将多个文件作为数组传递,例如:
MyScript -installdir c:\ file-1.txt,file-2.txt,file-3.txt
注意:为了接受来自 Get-Item 和 Get-ChildItem 等命令的输入,请使用 ValueFromPipelineByPropertyName 并添加参数别名“PSPath”,它将在 Get-Item/Get-ChildItem 输出的对象上找到 PSPath 属性。
我在 ISE 中对此进行了测试,它工作正常:
function foo
{
param(
[Parameter(
Position=0,
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true)]
[Alias('PSPath')]
[string[]]
$files,
$installdir,
$compilemode
)
process {
foreach ($file in $files) {
"File is $file, installdir: $installdir, compilemode: $compilemode"
}
}
}
foo a,b,c -installdir c:\temp -compilemode x64
ls $home -file | foo -installdir c:\bin -compilemode x86
仅供参考,这是我一直用来创建接受管道输入或数组输入以及通配符路径的命令的模板:
function Verb-PathLiteralPath
{
[CmdletBinding(DefaultParameterSetName="Path",
SupportsShouldProcess=$true)]
#[OutputType([output_type_here])] # Uncomment this line and specify the output type of this
# function to enable Intellisense for its output.
param(
[Parameter(Mandatory=$true,
Position=0,
ParameterSetName="Path",
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true,
HelpMessage="Path to one or more locations.")]
[ValidateNotNullOrEmpty()]
[SupportsWildcards()]
[string[]]
$Path,
[Alias("PSPath")]
[Parameter(Mandatory=$true,
Position=0,
ParameterSetName="LiteralPath",
ValueFromPipelineByPropertyName=$true,
HelpMessage="Literal path to one or more locations.")]
[ValidateNotNullOrEmpty()]
[string[]]
$LiteralPath
)
Begin
{
Set-StrictMode -Version Latest
}
Process
{
if ($psCmdlet.ParameterSetName -eq "Path")
{
if (!(Test-Path $Path)) {
$ex = new-object System.Management.Automation.ItemNotFoundException "Cannot find path '$Path' because it does not exist."
$category = [System.Management.Automation.ErrorCategory]::ObjectNotFound
$errRecord = new-object System.Management.Automation.ErrorRecord $ex, "PathNotFound", $category, $Path
$psCmdlet.WriteError($errRecord)
}
# In the -Path (non-literal) case, resolve any wildcards in path
$resolvedPaths = $Path | Resolve-Path | Convert-Path
}
else
{
if (!(Test-Path $LiteralPath)) {
$ex = new-object System.Management.Automation.ItemNotFoundException "Cannot find path '$LiteralPath' because it does not exist."
$category = [System.Management.Automation.ErrorCategory]::ObjectNotFound
$errRecord = new-object System.Management.Automation.ErrorRecord $ex, "PathNotFound", $category, $LiteralPath
$psCmdlet.WriteError($errRecord)
}
# Must be -LiteralPath
$resolvedPaths = $LiteralPath | Convert-Path
}
foreach ($rpath in $resolvedPaths)
{
if ($pscmdlet.ShouldProcess($rpath, "Operation"))
{
# .. process rpath
}
}
}
End
{
}
}
