powershell简单的使用gui 构建图形界面

powershell作为win的官方shell，可以调用.net对象。让它可以无所不能。例如给脚本加上图形界面更直观。而且这是win占用文件体积最小的图形程序。几行文本就能构建一个gui程序。py虽然也可以，但是要装环境。

如何为 PowerShell 脚本创建 GUI？– IT宝 (theitbros.com)

从简单到复杂

1.使用Out-GridView来展示结果。

1.1以下脚本将列出 Windows 上运行的服务

$Svcs = Get-Service | Where-Object {$_.Status -EQ "Running"}| Out-GridView -Title "List of running services" -PassThru| Select -ExpandProperty Name

1.2构建一个 GUI，以使用 Out-Gridview cmdlet 将当前正在运行的进程导出到具有筛选器的窗体。可以看出，可以根据进程 CPU、进程 SI、进程名称或进程 ID 对结果进行排序。还有一个用于添加过滤条件的过滤器。还有一个用于搜索输出的搜索框。这为用户提供了更好的GUI，用户可以直接在屏幕上过滤或执行任何他想做的事情，而不是将输出发送到文件，然后手动搜索或过滤。其中只有一个 cmdlet，因此未创建任何函数。为四列创建一个简单的数组，并分配其相应的值。

Write-Host "Demo of dispalying out grid in a GUI with search" -ForegroundColor Green
$pro_arry = @()
$processes = Get-Process | Select Name, Id, CPU, SI
Foreach ($process in $processes){
$pro_arry += New-Object PSObject -Property @{
Process_Name = $process.Name
Process_CPU = $process.CPU
Process_Id = $process.Id
Process_SI = $process.SI
}
}
$op = $pro_arry | Out-GridView -Title "Custome grid with Filters" -OutputMode Multiple

 

 

2.一些常用的交互

2.1显示消息框

 

[void] [System.Windows.MessageBox]::Show( "All changes have been implemented successfully ", "Script completed", "OK", "Information" )

2.2 显示一个消息框，其中包含必选项： 

$answer = [System.Windows.MessageBox]::Show( "Dou you want to remove this user?", " Removal Confirmation", "YesNoCancel", "Warning" )

2.3 显示默认的 Windows 选择文件对话框，并按文件名进行筛选

Add-Type -AssemblyName System.Windows.Forms

$initialDirectory = [Environment]::GetFolderPath('Desktop')

$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog

$OpenFileDialog.InitialDirectory = $initialDirectory

$OpenFileDialog.Filter = 'Script files (*.ps1;*.cmd;*.bat)|*.ps1;*.bat;*.cmd'

$OpenFileDialog.Multiselect = $false

$response = $OpenFileDialog.ShowDialog( ) # $response can return OK or Cancel

if ( $response -eq 'OK' ) { Write-Host 'You selected the file:' $OpenFileDialog.FileName }

2.4打开浏览文件夹对话框窗口

$shell = New-Object -ComObject Shell.Application

$selectedfolder = $shell.BrowseForFolder( 0, 'Select a folder to proceed', 16, $shell.NameSpace( 17 ).Self.Path ).Self.Path

2.5 选择打印机对话框窗体

Add-Type -AssemblyName System.Windows.Forms

$prntdlg = New-Object System.Windows.Forms.PrintDialog

$prntdlg.AllowCurrentPage = $false

$prntdlg.AllowPrintToFile = $trur

$prntdlg.AllowSelection = $false

$prntdlg.AllowSomePages = $true

$prntdlg.ShowNetwork = $true

$response = $prntdlg.ShowDialog( )# $response can return OK or Cancel

if ( $response -eq 'OK' ) { Write-Host 'Selected printer:' $prntdlg.PrinterSettings.PrinterName }

3.使用form构建。本质上是在调用.net   windows.forms对象

使用过vs构建过gui程序的应该很快能看懂。例如

[void][System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$inputform = New-Object System.Windows.Forms.Form
$inputform.Text = "Demo of text box input"
$inputform.Size = New-Object System.Drawing.Size(300,300)
$inputform.StartPosition = "CenterScreen"
$OKB = New-Object System.Windows.Forms.Button
$OKB.Location = New-Object System.Drawing.Size(65,120)
$OKB.Size = New-Object System.Drawing.Size(65,23)
$OKB.Text = "Submit"
$OKB.Add_Click({Write-Host "Entered value is"$OTB.Text -ForegroundColor Green;$inputform.Close()})
$inputform.Controls.Add($OKB)
$CAB = New-Object System.Windows.Forms.Button
$CAB.Location = New-Object System.Drawing.Size(140,120)
$CAB.Size = New-Object System.Drawing.Size(65,23)
$CAB.Text = "Clear"
$CAB.Add_Click({Write-Host "No input from user" -ForegroundColor Red;$inputform.Close()})
$inputform.Controls.Add($CAB)
$Lbl = New-Object System.Windows.Forms.Label
$Lbl.Location = New-Object System.Drawing.Size(10,20)
$Lbl.Size = New-Object System.Drawing.Size(260,20)
$Lbl.Text = "Please provide a value"
$inputform.Controls.Add($Lbl)
$OTB = New-Object System.Windows.Forms.TextBox
$OTB.Location = New-Object System.Drawing.Size(10,50)
$OTB.Size = New-Object System.Drawing.Size(240,20)
$inputform.Controls.Add($OTB)
$inputform.Topmost = $True
$inputform.Add_Shown({$inputform.Activate()})
[void] $inputform.ShowDialog()

4.使用vs生成 xaml文档，ps调用构建复杂gui

5.使用专业工具。推荐powershell studio  

 

这个是真正的专业工具。网上有你懂得版本。不过能用到这个，起码得懂不少ps和c#知识了。而且是纯英文界面
