使用GUI选择文件后，我想打开文件。尝试执行代码时，无法打开所选文件。它返回Get-Content找不到路径。任何人都可以帮助我。
Function File ($InitialDirectory)
{
Add-Type -AssemblyName System.Windows.Forms
$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$OpenFileDialog.Title = "Please Select File"
$OpenFileDialog.InitialDirectory = $InitialDirectory
$OpenFileDialog.filter = “All files (*.*)| *.*”
If ($OpenFileDialog.ShowDialog() -eq "Cancel")
{
[System.Windows.Forms.MessageBox]::Show("No File Selected. Please select a file !", "Error", 0,
[System.Windows.Forms.MessageBoxIcon]::Exclamation)
} $Global:SelectedFile = $OpenFileDialog.SafeFileName
Get-Content "$Global:SelectedFile" | ForEach-Object {
$_.Trim()
} | Where-Object {
$_ -notmatch '^(;|$)'
} | ForEach-Object {
if ($_ -match '^\[.*\]$') {
$section = $_ -replace '\[|\]'
$ini_file[$section] = @{}
} else {
$key, $value = $_ -split '\s*=\s*', 2
$ini_file[$section][$key] = $value
}
}
}

$Close.location = New-Object System.Drawing.Point(450,190)
$Close.Add_Click({$Form.Close()})
#----------
$Choose2.Add_Click({Sel_File
$Sel.Text = $Global:SelectedFile
})
$Form.Controls.AddRange(@($Choose1, $Sel, $Choose2, $Close))
[void] $Form.ShowDialog()
我的期望是，我可以打开该文件，因为我想处理该文件。我要打开的文件是.INI文件。 请帮助，任何人。谢谢

我使用了已编辑的代码，但无法处理该按钮。选择文件后，我想阅读INI节[Location]。使用此代码，在选择文件之前已经打印了该部分。

根据我的评论，您需要将$OpenFileDialog.SafeFileName更改为$OpenFileDialog.FileName。
# SafeFileName = "Config.ini"
# FileName = "\\UNC\Path\Config.ini" or "C:\Temp\Config.ini"
Function File ($InitialDirectory) {
Add-Type -AssemblyName System.Windows.Forms
$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$OpenFileDialog.Title = "Please Select File"
$OpenFileDialog.InitialDirectory = $InitialDirectory
$OpenFileDialog.filter = “All files (*.*)| *.*”
If ($OpenFileDialog.ShowDialog() -eq "Cancel")
{
[System.Windows.Forms.MessageBox]::Show("No File Selected. Please select a file !", "Error", 0,
[System.Windows.Forms.MessageBoxIcon]::Exclamation)
} $Global:SelectedFile = $OpenFileDialog.FileName
Get-Content "$Global:SelectedFile" | ForEach-Object {
$_.Trim()
} | Where-Object {
$_ -notmatch '^(;|$)'
} | ForEach-Object {
if ($_ -match '^\[.*\]$') {
$section = $_ -replace '\[|\]'
$ini_file[$section] = @{}
} else {
$key, $value = $_ -split '\s*=\s*', 2
$ini_file[$section][$key] = $value
}
}

您根本不需要全局变量。基本上，主要形式应将对话框中的$Sel.Text捕获到变量中，检查是否不是“ Selected”的默认值以及应该这样做：
function Select-File ($InitialDirectory) {
Add-Type -AssemblyName System.Windows.Forms
$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$OpenFileDialog.Title = "Please Select File"
$OpenFileDialog.InitialDirectory = $InitialDirectory
$OpenFileDialog.filter = "All files (*.*)| *.*"
If ($OpenFileDialog.ShowDialog() -eq "Cancel") {
[System.Windows.Forms.MessageBox]::Show("No File Selected. Please select a file !", "Error", 0,
[System.Windows.Forms.MessageBoxIcon]::Exclamation)
$result = $null
}
else {
$result = $OpenFileDialog.FileName
}
$OpenFileDialog.Dispose()
return $result
}
function Get-IniContent ($FilePath) {
$ini = @{}
switch -regex -file $FilePath
{
"^\[(.+)\]" # Section
{
$section = $matches[1]
$ini[$section] = @{}
$CommentCount = 0
}
"^(;.*)$" # Comment
{
$value = $matches[1]
$CommentCount = $CommentCount + 1
$name = "Comment" + $CommentCount
$ini[$section][$name] = $value
}
"(.+?)\s*=(.*)" # Key
{
$name,$value = $matches[1..2]
$ini[$section][$name] = $value
}
}
return $ini
}
