我尝试使用具有目录名称的按钮创建动态表单。单击按钮应该获取目录名称并进行处理。

code sinpped:

{function convert_it($arg)

    $dir = "$source\$arg"
    $dir_liste =  Get-ChildItem $dir | Where-Object {$_.mode -match "d"} 
    $dir_count_total = $dir_liste.count

...

...

...

}



foreach ($dir in $dir_list)

{   
# Button
if ($split_count -eq 25){
    $x=250
    $y=50
}
elseif ($split_count -eq 50){
    $x=500
    $y=50
}

$dir_numbers = (get-childitem -Path $source\$dir -recurse | where-object { 
$_.PSIsContainer }).Count

$run = New-Object System.Windows.Forms.Button
$run.Location = New-Object System.Drawing.Size($x,$y)
$run.Size = New-Object System.Drawing.Size(100,20)
if ($dir_numbers -eq 0) {
    $run.Enabled = $false
}
$run.Text = "#$dir_count -> $dir -> $dir_numbers"

$run.Add_Click({ convert_it($dir) }.GetNewClosure())

$testForm.Controls.Add($run)
$Font = New-Object System.Drawing.Font("Times New Roman",14,
[System.Drawing.FontStyle]::Regular)
$run.font = $Font
$run.AutoSize = $True
$y+=30
$split_count+=1
$dir_count+=1

}







$testForm.ShowDialog()

当我运行脚本时,出现以下错误:

convert_it:术语“convert_it”未被识别为cmdlet,函数,脚本文件或可操作程序的名称。检查名称的拼写,或路径是否正确 包含,验证路径是否正确,然后重试。

  • $ run.Add_Click({convert_it($ dir)}。GetNewClosure())
  • ~~~~~~~~~~
    • CategoryInfo:ObjectNotFound:(convert_it:String)[],CommandNotFoundException
    • FullyQualifiedErrorId:CommandNotFoundException

我在这里错了什么?:

$run.Add_Click({ convert_it $dir }.GetNewClosure())

答案 0 :(得分:0)

看起来你的函数的开放括号位于错误的位置(应该在行的末尾而不是在开头(这使得它成为一个scriptblock)。

应该是这样的:

function convert_it($arg) {

    $dir = "$source\$arg"
    $dir_liste =  Get-ChildItem $dir | Where-Object {$_.mode -match "d"} 
    $dir_count_total = $dir_liste.count
    ...
}
