Question

我在这里挣扎。

获取此示例代码：

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

$objForm = New-Object System.Windows.Forms.Form 
$objForm.Text = "Data Entry Form"
$objForm.Size = New-Object System.Drawing.Size(500,400) 
$objForm.StartPosition = "CenterScreen"

$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter") 
    {$output1=$objTextBox.Text}})
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape") 
    {$objForm.Close()}})

$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(100,90)
$OKButton.Size = New-Object System.Drawing.Size(75,23)
$OKButton.Text = "Merge"
$OKButton.Add_Click({$output=$objTextBox.Text})
$objForm.Controls.Add($OKButton)

$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Size(300,90)
$CancelButton.Size = New-Object System.Drawing.Size(75,23)
$CancelButton.Text = "Cancel"
$CancelButton.Add_Click({$objForm.Close()})
$objForm.Controls.Add($CancelButton)

$objLabel = New-Object System.Windows.Forms.Label
$objLabel.Location = New-Object System.Drawing.Size(160,20) 
$objLabel.Size = New-Object System.Drawing.Size(280,20) 
$objLabel.Text = "Please enter the target machine: "
$objForm.Controls.Add($objLabel) 

$output = new-object System.Windows.forms.label
$output.location = new-object System.drawing.size(30, 140)
$output.size = New-Object System.Drawing.Size(300,300) 
$objform.controls.add($output)

$objTextBox = New-Object System.Windows.Forms.TextBox 
$objTextBox.Location = New-Object System.Drawing.Size(115,40) 
$objTextBox.Size = New-Object System.Drawing.Size(260,20) 
$objForm.Controls.Add($objTextBox) 

$objForm.Topmost = $True

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

我不能为我的生活弄清楚为什么当我在框中输入文本并单击OKButton（Merge）时没什么好笑的。它应该输出到$ output，或者至少，这就是我想要发生的事情。

我只是试图让代码获取文本框的输入并将其输出到名为$ output的标签形式。

我已经开始工作，因为当我将输入放入文本框并按“合并”时，它会将其输出到Powershell_ISE控制台，但仅在窗口关闭后再运行第二次（当我按'合并'时，它不会刷新$ output标签，只有当我关闭程序时才输出）

请帮忙！

谢谢

修改

$OKButton.Add_Click({$output=$objTextBox.Text})

到

$OKButton.Add_Click({$output.text=$objTextBox.Text})

使用Powershell GUI + Refresh
