functionTest-MrParameter{param($ComputerName)Write-Output$ComputerName} 以下函数可查询系统中的所有命令,并返回带有特定参数名称的命令编号。 PowerShell functionGet-MrParameterCount{param( [string[]]$ParameterName)foreach($Parameterin$ParameterName) {$Results=Get-Command-ParameterName$Parameter-ErrorActionSil...
接受按属性名称显示的管道输入是类似的,但它是使用ValueFromPipelineByPropertyName参数属性指定的。 管道输入一次输入一个项,这类似于在foreach循环中处理项的方式。 如果要接受数组作为输入,则至少需要一个process块才能处理所有项。 functionTest-MrPipelineInput { [CmdletBinding()]param( [Parameter(Mandatory, Value...
If the function is invoked without pipeline input, PowerShell executes theprocessblock only once. Within a pipeline, theprocessblock executes once for each input object that reaches the function. If the pipeline input that reaches the function is empty, theprocessblock doesn't execute. ...
true Position? 0 Default value None Accept pipeline input? True (ByPropertyName, ByValue) Accept wildcard characters? false 通过管道Start-Service将对象发送到 时,PowerShell 会尝试将对象与InputObject和Name参数相关联。 接受管道输入的方法 Cmdlet 参数可以通过以下两种不同方式之一接受管道输入: ...
understood, we can start to develop our own advanced functions while improving our scripting knowledge and capabilities. These are functions that can integrate parameters which accept pipeline input, and in fact this is how many of the native PowerShell cmdlets already work....
function inc ([parameter(ValueFromPipeline)]$x) {return $x + 1} Write-Host (3 | inc) #输出为:4 五、使用引用 函数参数可使用引用类型,使用引用类型之后便可以在函数中修改外部变量的数值。 在参数前使用[ref]指定使用引用类型。如function f ([ref]$x)。传参时,要求把传入数值转换为引用类型,转换...
My function expects its pipeline input to be simple string objects. The function wouldn't work if I were to replace the Get-Content command with, say, a cmdlet to retrieve all the computer names from Active Directory, like this:Copy Get-QADComputer | Get-SPInventory ...

-InputObject 与停止分析标记 (--%) 不同,--标记后面的任何值都可以被 PowerShell 解释为表达式。 PowerShell Write-Output---InputObject$env:PROCESSOR_ARCHITECTURE Output -InputObject AMD64 此行为仅适用于 PowerShell 命令。 如果在调用外部命令时使用--标记,--字符串将作为参数传递给该命令。
Accepts Pipeline Input This setting indicates whether you can use the pipeline operator (|) to send a value to the parameter. Value Description --- --- False Indicates that you cannot pipe a value to the parameter. True (by Value) Indicates that you can pipe any value to the parameter,...
