将变量绑定到Powershell中的combobox和textbox

# 导入Windows Forms命名空间
Add-Type -AssemblyName System.Windows.Forms

# 创建一个Windows Forms窗体
$form = New-Object System.Windows.Forms.Form
$form.Size = New-Object System.Drawing.Size(300, 200)

# 创建一个combobox控件
$combobox = New-Object System.Windows.Forms.ComboBox
$combobox.Location = New-Object System.Drawing.Point(50, 50)
$combobox.DropDownStyle = 'DropDownList'  # 设置为只能选择
$form.Controls.Add($combobox)

# 创建一个textbox控件
$textbox = New-Object System.Windows.Forms.TextBox
$textbox.Location = New-Object System.Drawing.Point(50, 100)
$form.Controls.Add($textbox)

# 定义一个变量
$selectedValue = ''

# 绑定combobox的SelectedIndexChanged事件
$combobox.add_SelectedIndexChanged({
    $selectedValue = $combobox.SelectedItem.ToString()
    $textbox.Text = $selectedValue
})

# 显示窗体
$form.ShowDialog()
