PowerShell foreach循环打印过多：我希望它仅打印我要打印的内容

Question

在PowerShell中，我想遍历其中包含多个项目的对象，但是我只想查看两个项目，即路径和名称，并对它们进行一些逻辑处理。问题是，如果我使用foreach或ForEach-Object，当我不希望它们打印时，它会立即打印出$line.Name和$line.Path。

尝试foreach和ForEach-Object，尝试void和| Out-Null，尝试$element.Name.ToString()。

void和Out-Null几乎擦除了整个内容，因此我看不到任何值，而且我仍然可以看到void或Out-Null处的空白行线在。

ToString()仍会打印该值。

foreach ($line in $buildPipelineObject) {
    # $line.* has leading and trailing spaces, want to trim them
    $trimPath = $line.Path  # don't print!
    $trimPath.Trim()
    $trimName = $line.Name.ToString()  # don't print!
    #[void]Set-Variable -Name "trimName" -Value $line.Name # makes trimName null 
    $trimName.Trim()

    # if pipeline isn't in a subfolder, then I don't need to insert backslash
    if ($trimPath -eq "\") {
        $pipelineName = $trimPath + $trimName
    } else {
        $pipelineName = $trimPath + "\" + $trimName
    }
    Write-Host "pipeline: $pipelineName"
}

问题是，我运行此代码块，然后看到类似

的内容

\
pipelinename1
pipeline: \pipelinename1
\myfolder
pl2
pipeline: \myfolder\pl2

我只想看到输出的“ pipeline：”行，例如

pipeline: \pipelinename1
pipeline: \myfolder\pl2
