您可以通过将一段代码 Package 在ScriptBlock {...}中来 * 延迟 * 执行它：

# Variable now contains a scriptblock with code that we can invoke later!
$MoveToTest = { Move-Item -Path "C:\Test.jpg" -Destination "C:\Test Folder" -force -ea 0 }

# Code
If (Test-Path C:\*.mp4) {
    # Use the `&` invocation operator to execute the code now!
    &$MoveToTest
}

这类似于function关键字的工作方式--它只是将脚本块与函数名而不是变量相关联--当然，您也可以定义一个函数：

function Move-TestJpgToTestFolder {
    Move-Item -Path "C:\Test.jpg" -Destination "C:\Test Folder" -force -ea 0
}

# Code
If (Test-Path C:\*.mp4) {
    # We no longer need the `&` invocation operator to execute the code, PowerShell will look up the function name automatically!
    Move-TestJpgToTestFolder
}
