您是否具有需要接受文本输入的PowerShell GUI？也许您希望能够复制并粘贴计算机，IP地址，用户名或其他数据的列表。我将向您展示如何在PowerShell GUI中添加文本框来处理该输入。如果您还没有创建PowerShell GUI，但是对此感兴趣，请查看我以前的文章中有关如何制作简单GUI的文章。
码
让我们开始分解实现此目标所需的代码部分。我喜欢将输入框代码放在函数中，但是您可能会决定不想这样做。要查看整个代码，请查看我的GitHub。
我们需要做的第一件事是通过.NET Windows窗体命名空间创建窗体。在这里，我们在窗口标题中指定所需的文本，以及所需的大小。某些可选设置是使窗口开始于屏幕中心，以防止调整窗口大小并将该窗口置于其他打开的窗口之上。

### Creating the form with the Windows forms namespace
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing
$form = New-Object System.Windows.Forms.Form
$form.Text = 'Enter the appropriate information' ### Text to be displayed in the title
$form.Size = New-Object System.Drawing.Size(310,625) ### Size of the window
$form.StartPosition = 'CenterScreen' ### Optional - specifies where the window should start
$form.FormBorderStyle = [System.Windows.Forms.FormBorderStyle]::FixedToolWindow ### Optional - prevents resize of the window
$form.Topmost = $true ### Optional - Opens on top of other windows
|
接下来，我们将在窗口底部添加一个确定按钮。输入数据后，用户将单击“确定”按钮将输入传递到GUI的下一步。

### Adding an OK button to the text box window
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Point(155,550) ### Location of where the button will be
$OKButton.Size = New-Object System.Drawing.Size(75,23) ### Size of the button
$OKButton.Text = 'OK' ### Text inside the button
$OKButton.DialogResult = [System.Windows.Forms.DialogResult]::OK
$form.AcceptButton = $OKButton
$form.Controls.Add($OKButton)
|
然后，如果用户决定不运行GUI，我们将添加一个取消按钮。

### Adding a Cancel button to the text box window
$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Point(70,550) ### Location of where the button will be
$CancelButton.Size = New-Object System.Drawing.Size(75,23) ### Size of the button
$CancelButton.Text = 'Cancel' ### Text inside the button
$CancelButton.DialogResult = [System.Windows.Forms.DialogResult]::Cancel
$form.CancelButton = $CancelButton
$form.Controls.Add($CancelButton)
|
为了避免混淆并帮助用户了解要输入什么类型的数据，我们将添加标签。该标签将由调用函数时使用的参数定义。如果要对标签文本进行硬编码，只需将$ Input_Type替换为要显示的文本。

### Putting a label above the text box
$label = New-Object System.Windows.Forms.Label
$label.Location = New-Object System.Drawing.Point(10,10) ### Location of where the label will be
$label.AutoSize = $True
$Font = New-Object System.Drawing.Font("Arial",12,[System.Drawing.FontStyle]::Bold) ### Formatting text for the label
$label.Font = $Font
$label.Text = $Input_Type ### Text of label, defined by the parameter that was used when the function is called
$label.ForeColor = 'Red' ### Color of the label text
$form.Controls.Add($label)
|
GUI窗口的最后一部分是文本框，它将用于接受输入的文本。

### Inserting the text box that will accept input
$textBox = New-Object System.Windows.Forms.TextBox
$textBox.Location = New-Object System.Drawing.Point(10,40) ### Location of the text box
$textBox.Size = New-Object System.Drawing.Size(275,500) ### Size of the text box
$textBox.Multiline = $true ### Allows multiple lines of data
$textbox.AcceptsReturn = $true ### By hitting enter it creates a new line
$textBox.ScrollBars = "Vertical" ### Allows for a vertical scroll bar if the list of text is too big for the window
$form.Controls.Add($textBox)

将画龙点睛放在一起，使它们一起工作并清理输入的数据。

$form.Add_Shown({
$textBox.Select()}) ### Activates the form and sets the focus on it
$result = $form.ShowDialog() ### Displays the form
### If the OK button is selected do the following
if ($result -eq [System.Windows.Forms.DialogResult]::OK)
{
### Removing all the spaces and extra lines
$x = $textBox.Lines | Where{
$_} | ForEach{ $_.Trim() }
### Putting the array together
$array = @()
### Putting each entry into array as individual objects
$array = $x -split "`r`n"
### Sending back the results while taking out empty objects
Return $array | Where-Object {
$_ -ne ''}
}
### If the cancel button is selected do the following
if ($result -eq [System.Windows.Forms.DialogResult]::Cancel)
{
Write-Host "User Canceled" -BackgroundColor Red -ForegroundColor White
Write-Host "Press any key to exit..."
$Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
Exit
}

呼叫文字方块
既然创建GUI文本框的代码已经完成，我们需要调用文本框并返回输入的数据。我将分享一些有关如何利用我们刚创建的文本框的示例。下面的示例假定您已使用参数将文本框放入函数中。

这是一个如何使用文本框接受计算机名称列表的示例。本示例将仅输出输入到屏幕的计算机名称列表。为了使此功能有用，您将需要添加代码以使脚本对这些计算机名称起作用。也许您需要在计算机列表上执行电源操作或任何数量的管理员操作。

### Computer Name(s) example of how to utilize the GUI_TextBox function
###############################################################################
$Computers = GUI_TextBox "Computer Names(s):" ### Calls the text box function with a parameter and puts returned input in variable
$Computer_Count = $Computers | Measure-Object | % {
$_.Count} ### Measures how many objects were inputted
If ($Computer_Count -eq 0){ ### If the count returns 0 it will throw and error
Write-Host "Nothing was inputed..." -BackgroundColor Red -ForegroundColor White
Return

Else { ### If there was actual data returned in the input, the script will continue
Write-Host "Number of computers entered:" $Computer_Count -BackgroundColor Cyan -ForegroundColor Black
$Computers
### Here is where you would put your specific code to take action on those computers inputted
