Question

我有一个正在运行的脚本。它要求http链接，然后将其传递给Vlc视频播放器。现在，我试图让它看起来更漂亮，并添加一个表格框，再次输入http链接，然后我现在调用$ X的输入变量将传递给Vlc视频播放器。新脚本上的代码出现问题，Vlc播放器无法打开。谁能帮助我？感谢

工作脚本

$link = read-host "Enter your Http Link" 
$ip = read-host "Enter your Local Ip Address:Port "
$processArgs = "$link",":sout=#transcode{vcodec=VP80,vb=2000,acodec=vorb,ab=128,
channels=2,samplerate=44100}:http{mux=webm,dst=:8080/stream} :sout-all :sout-keep"
start-process "C:\Program Files\VideoLAN\VLC\vlc.exe" $processArgs    
& "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"    
"https://dabble.me/cast/?video_link=http://$ip/stream"

非工作脚本

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")

$objForm.StartPosition = "CenterScreen"
$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter") 
{$x=$objTextBox.Text;$objForm.Close()}})
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape") 
{$objForm.Close()}})
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(75,120)
$OKButton.Size = New-Object System.Drawing.Size(75,23)

$objForm.Controls.Add($objTextBox) 

$objForm.Topmost = $True

$objForm.Add_Shown({$objForm.Activate()})
[void] $objForm.ShowDialog()

**$x** 

$ip = read-host "Enter your Local Ip Address:Port "
$processArgs = "$x",":sout=#transcode{vcodec=VP80,vb=2000,acodec=vorb,

<强>修正：

Try replacing $x with $Script:x everywhere in your script

<强>解释

您假设脚本块中的$ x可以从外部访问。不是。您可以克服这个问题的一种方法是使用$ script：VariableName方法。您以这种方式定义的变量将对该脚本中的所有代码块可见

变量未被传递
