Question

我有一个使用filesystemwatcher监视路径中文件夹的代码。

当用户在GUI中输入时，我需要它监视的路径基于两个字段中的输入进行更改。点击按钮后即可开始监视。

我确实有一个GUI可以像这样工作，它基于填写的这两个字段来启动.bat文件。（实际上，我需要同时启动两个GUI，因为第一个打开文件并将文件保存到需要监视的文件夹中。）

我似乎无法让filesystemwatcher在同一单击上运行。

我尝试了各种方法将两者结合起来一起工作，但没有任何乐趣。但是由于我对任何一种编码都不熟悉，所以我不知道自己在做错什么。

这是文件系统监视程序代码，当在文件夹中检测到文件时，该代码应运行.bat文件。 Folder1和Folder2需要能够根据GUI的输入进行更改。

$folder = 'c:\Work\Folder1\Folder2\Destination' 
$filter = '*.*'

$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property @{IncludeSubdirectories = $true;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}

Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
Write-Host "The file '$name' was $changeType at $timeStamp" -fore green
Out-File -FilePath c:\temp\log\Filelog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"
Set-Location "c:\Work\Folder1\Folder2\Destination"
Start-Process "c:\Work\Folder1\Folder2\Destination\PS_Run.bat"
}

下面是现有（Run.bat）代码在GUI中的工作方式

$TextBox.multiline = $false
$TextBox.location = New-Object System.Drawing.Point(50,50)
$TextBox.size = New-Object System.Drawing.Size(400,50)
$TextBox.Font = 'Microsoft Sans Serif,10'



$TextBox2 = New-Object system.Windows.Forms.TextBox
$TextBox2.multiline = $false
$TextBox2.location = New-Object System.Drawing.Point(50,110)
$TextBox2.size = New-Object System.Drawing.Size(400,50)
$TextBox2.Font = 'Microsoft Sans Serif,10'

\Folder1\Folder2\
$($TextBox.text)\$($TextBox2.text)

$TextBox到$($TextBox.text)在一种情况下有效，但在另一种情况下无效，我需要他们共同努力。

我得到的错误是
