我需要WebClient在PowerShell 2.0中下载文件,我想显示下载进度,所以我这样做:

$activity = "Downloading"

$client = New-Object System.Net.WebClient
$urlAsUri = New-Object System.Uri($url)

$event = New-Object System.Threading.ManualResetEvent($false)

$downloadProgress = [System.Net.DownloadProgressChangedEventHandler] {
    $progress = [int]((100.0 * $_.BytesReceived) / $_.TotalBytesToReceive)
    Write-Progress -Activity $activity -Status "${progress}% done" -PercentComplete $progress
}

$downloadComplete = [System.ComponentModel.AsyncCompletedEventHandler] {
    Write-Progress -Activity $activity -Completed
    $event.Set()
}

$client.add_DownloadFileCompleted($downloadComplete) 
$client.add_DownloadProgressChanged($downloadProgress)

Write-Progress -Activity $activity -Status "0% done" -PercentComplete 0
$client.DownloadFileAsync($urlAsUri, $file)    

$event.WaitOne()

我There is no Runspace available to run scripts in this thread.在$downloadProgress处理程序中遇到错误,这是合乎逻辑的.但是,我如何Runspace为(可能)属于的线程提供ThreadPool …

我有脚本监视特定目录中的文件创建。\n我在创建 System.IO.FileSystemWatcher 后使用 Register-ObjectEvent，

它工作得很好，但如果我在 -Action 代码块中设置断点，IDE 会生成：

警告：不会命中 \'D:\\My Stuff\\Desktop\\scripts\\fileWatcher.ps1:15\' 上的断点行断点

在我将文件放入我正在监视的目录中后，此消息立即发生，并且我可以看到我的写入主机在上述“警告”之后立即打印出我的消息。

这是正常的吗？
\n我需要添加更多代码并且可以真正使用调试器..\n我应该做什么，以便我可以调试此代码块？

$fsw = [System.IO.FileSystemWatcher] $path\n\nRegister-ObjectEvent -InputObject $fsw \xe2\x80\x93EventName Created -SourceIdentifier DDFileCreated -Action { \n    $name = $Event.SourceEventArgs.Name \n    $changeType = $Event.SourceEventArgs.ChangeType \n    $timeStamp = $Event.TimeGenerated \n    Write-Host "The file \'$name\' was $changeType at $timeStamp" -fore green \n    Out-File -FilePath $logFile -Append -InputObject "The file \'$name\' was $changeType at $timeStamp"\n} \n
