Powershell中的Exit函数导致未处理的异常错误

Question

我在一个简单的PowerShell表单上重新创建了这个错误，它在我创建的每一个代码中都不断发生。我想用退出按钮退出整个程序。但我得到了例外。有人能帮忙吗？

Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing

$Form = New-Object System.Windows.Forms.Form
$Form.Text = "press Exit to Quit"
$Form.minimumSize = New-Object System.Drawing.Size(200, 200)
$Form.maximumSize = New-Object System.Drawing.Size(200, 200)
$Form.TopMost = "True"
$Form.ShowInTaskbar = "True"
$Form.StartPosition = "CenterScreen"
$Form.FormBorderStyle = [System.Windows.Forms.FormBorderStyle]::Fixed3D

$Exit = New-Object System.Windows.Forms.Button;
$Exit.Text = "Exit"
$Exit.Location = New-Object System.Drawing.Point(100, 50)
$Exit.add_click({Exit}) 




$Form.Controls.Add($Exit)


$Form.ShowDialog()    

错误文本也是：

Answer 1

我不知道$Exit.add_click({Exit})应该做什么。

$Exit.Add_Click({
$Form.Close()
})
