PowerShell 中的 OpenFileDialog - 可以更改对话框的图标吗？

Question

我有这段代码将调用OpenFileDialog类。

似乎没有更改对话框左上角显示的对话框图标的属性。

有没有办法改变这个？

这是代码：

Function Invoke-OpenFileDialog {

  Param (
    [Parameter(Mandatory=$true, Position=0)] [string] $Title,
    [Parameter(Mandatory=$true, Position=1)] [string] $InitialDirectory,
    [Parameter(Mandatory=$true, Position=2)] [string] $Filter
    )

  Add-Type -AssemblyName System.Windows.Forms

  if ($InitialDirectory -ne "") {
    if (!(Test-Path -LiteralPath $InitialDirectory -PathType Container)) {
      $InitialDirectory = ([System.IO.FileInfo]$InitialDirectory).DirectoryName
    }
  }

  $OpenFileDialog                  = New-Object System.Windows.Forms.OpenFileDialog
  $OpenFileDialog.Filter           = $Filter
  $OpenFileDialog.InitialDirectory = $InitialDirectory
  $OpenFileDialog.Title            = $Title
  $result                          = $OpenFileDialog.ShowDialog()
  $OpenFileDialog.Dispose()

  if ($result -eq 'OK') {
    return $OpenFileDialog.FileName
  }
  else { return "" }

}

$title = 'OpenFileDialog Title'
$initialDirectory = ([System.IO.FileInfo]"C:\Users\").DirectoryName
$filter = 'All files (*.*)| *.*'

$filePicked = Invoke-OpenFileDialog -Title $title -InitialDirectory $initialDirectory -Filter $filter

# Then use this to check if the picker has done its job.
if ($filePicked -ne "") {
  $filePicked
  Write-Host 'File Picked...'
}
else {
  Write-Host 'File Not Picked...'
}

有问题的图标：

Answer 1

找到了！

创建您的表单并使用我的代码从这里为该表单提供您自己的图标。

然后，从表单上的按钮（例如，使用函数）打开 OpenFile 对话框。 然后该对话框将具有在您的表单中使用的图标。

# start the code with your own function to show the OpenFile dialog
function Invoke-OpenFileDialog {

  Param (
    [Parameter(Mandatory=$true, Position=0)] [string] $Title,
    [Parameter(Mandatory=$true, Position=1)] [string] $InitialDirectory,
    [Parameter(Mandatory=$true, Position=2)] [string] $Filter
    )

  if ($InitialDirectory -ne "") {
    if (!(Test-Path -LiteralPath $InitialDirectory -PathType Container)) {
      $InitialDirectory = ([System.IO.FileInfo]$InitialDirectory).DirectoryName
    }
  }

  $OpenFileDialog                  = New-Object System.Windows.Forms.OpenFileDialog
  $OpenFileDialog.Filter           = $Filter
  $OpenFileDialog.InitialDirectory = $InitialDirectory
  $OpenFileDialog.Title            = $Title
  $result                          = $OpenFileDialog.ShowDialog()
  $OpenFileDialog.Dispose()

  if ($result -eq 'OK') {
    return $OpenFileDialog.FileName
  }
  else { return "" }

}

# next, create your form (just a simple demo below) and from there show the dialog
# (I'm using a button on the form to do this)
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

$form            = New-Object system.Windows.Forms.Form
$form.ClientSize = '400,230'
$form.text       = "Test"
$form.TopMost    = $false

# This base64 string holds the bytes that make up the 16x16 StackOverflow icon

现在，如果您运行它，您将看到以下表单：

如果您单击该按钮，则会显示对话框，其中包括您的表单图标：

您也可以为 WPF UI 执行此操作，但设置带有嵌入图标的 WPF 表单略有不同：

# start the code with your own function to show the OpenFile dialog
function Invoke-OpenFileDialog {
    Param (
    [Parameter(Mandatory=$true, Position=0)] [string] $Title,
    [Parameter(Mandatory=$true, Position=1)] [string] $InitialDirectory,

            $InitialDirectory = ([System.IO.FileInfo]$InitialDirectory).DirectoryName
        }
    }

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

Answer 2

我找到了一种通过设置独立于任何 UI 来设置图标的方法：

$OpenFileDialogForm = New-Object System.Windows.Forms.Form

并将 base64 字符串传递给$OpenFileDialogForm的icon属性。

然后将$OpenFileDialogForm传递给：

$userClicked = $OpenFileDialog.ShowDialog($OpenFileDialogForm) ,

Invoke-OpenFileDialog函数中的一些注释解释了这一点。

函数中的IconBase64参数是可以设置的地方。

这是代码：

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

Function Get-LastValidDirectory {

  Param
  (
    [Parameter(Mandatory = $true, HelpMessage = 'The literal path where the folder you want to check is, which will return the last valid folder.')]
    [Array]$LiteralPath
    )

  if (Test-Path -LiteralPath $LiteralPath -PathType Container) {
    # Returns the path passed to the function if it has been found.'
    return $LiteralPath
  }

  # Increment the input folder
  $lastDir = Split-Path -LiteralPath $LiteralPath

  # Test that folder for it not existing and check if it's doesn't exist and in the
  # while loop increment the $lastDir variable.
  while (!(Test-Path -LiteralPath $lastDir -PathType Container)) {
    $lastDir = Split-Path -LiteralPath $lastDir
  }

  return $lastDir

}

function Invoke-OpenFileDialog {

  Param (
    [Parameter(Mandatory=$true, Position=0)] [string] $Title,
    [Parameter(Mandatory=$true, Position=1)] [string] $InitialDirectory,
    [Parameter(Mandatory=$true, Position=2)] [string] $Filter,
    [Parameter(Mandatory=$true, Position=3)] [string] $IconBase64,
    [Parameter(Mandatory=$true, Position=4)] [boolean] $TopMost
    )

  if ($InitialDirectory -ne "") {
    if (!(Test-Path -LiteralPath $InitialDirectory -PathType Container)) {
      $InitialDirectory = ([System.IO.FileInfo]$InitialDirectory).DirectoryName
    }
  }

  # Create a streaming image by streaming the base64 string to a bitmap stream source.

  $IconBase64 = $IconBase64
  $iconBytes  = [Convert]::FromBase64String($IconBase64)
  $stream     = New-Object IO.MemoryStream($iconBytes, 0, $iconBytes.Length)
  $stream.Write($iconBytes, 0, $iconBytes.Length)

  # Create a new form to hold the object and set it properties for the main
  # OpenFileDialog form.

  $OpenFileDialogForm         = New-Object System.Windows.Forms.Form
  $OpenFileDialogForm.Icon    = [System.Drawing.Icon]::FromHandle((New-Object System.Drawing.Bitmap -Argument $stream).GetHIcon())
  $OpenFileDialogForm.TopMost = $TopMost

  # Set the properties of the main OpenFileDialog along with using the
  # OpenFileDialogForm properties from above.

  $OpenFileDialog                  = New-Object System.Windows.Forms.OpenFileDialog
  $OpenFileDialog.Filter           = $Filter
  $OpenFileDialog.InitialDirectory = $InitialDirectory
  $OpenFileDialog.Title            = $Title
  $userClicked                     = $OpenFileDialog.ShowDialog($OpenFileDialogForm)
  $OpenFileDialog.Dispose()

  if ($userClicked -eq 'OK') { return $OpenFileDialog.FileName } else { return "" }

}

$title = 'OpenFileDialog Title'
$initialDirectory = ([System.IO.FileInfo]"C:\Users\").DirectoryName + '\no folder here'
