使用PowerShell GUI无人参与的软件安装

Question

我想使用PowerShell创建GUI，这将允许用户选择要安装的软件。该软件将使用无人值守（静默）选项安装，因此用户无需执行其他任何操作即可选择所需的软件，然后单击“确定”。

由于安装是静默的，将要安装大量软件，因此我想向用户提供有关安装状态的反馈。因此，我在文本框中显示了已安装的软件和当前正在安装的软件。

我的问题是所有文本同时出现在文本框中，而且看起来也很乱。

我希望它像这样：

• 安装7-zip ...确定
• 安装记事本++ ...确定
• 安装Visual Studio代码...确定

这是脚本

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

# software name
$software1 = "7-Zip"
$software2 = "Notepad++"
$software3 = "Visual Studio Code"

# installation status
$software1status = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where {$_.DisplayName -like "*$software1*"}
$software2status = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where {$_.DisplayName -like "*$software2*"}
$software3status = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where {$_.DisplayName -like "*$software3*"}

# activate form

[void] $Form.ShowDialog()

改用AppendText。您还需要使用该方法发送回车符和换行符：

$ResultsTextBox.AppendText("`r`nInstalling new file...")

但是，您只能在按钮单击之类的事件期间执行此类操作。如果您想更频繁地更新，则需要为此创建事件。
