匹配两个列表并使用 Powershell 查找卸载字符串

Question

我的脚本有问题。我想制作一个脚本，列出在特定注册表路径中找到的软件并查看此软件是否等于已安装的软件。如果是这样，它应该输出卸载字符串。但现在它无法正常工作。它永远不会告诉我我想要的输出，即使它相似。例如，我将程序 Git 作为品牌，在软件中我得到了 Git 版本 2.26.2，但是当我选择 git.

时它不会输出卸载字符串

我的代码是：

$branding = Get-ChildItem "HKLM:\Software\DLR\Branding" | Get-ItemProperty | Select-Object -expandProperty ProgramName
$software = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Select-Object -ExpandProperty DisplayName

ForEach ($brandinglist in $branding) {
    $objCombobox.Items.Add("$brandinglist")
}

$objComboBox_SelectedIndexChanged=
{
    $selectme = $objCombobox.SelectedItem
    Write-Host $selectme
    if ("$selectme" -like "*$software*") {
        $uninstall = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall,     HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Where-Object {$_.DisplayName -match "$electme" } | Select-Object -Property UninstallString
        Write-Host "$uninstall"
    }
}

您正在尝试 -like 比较错误，您将所选项目与一组显示名称进行比较，但这种方式行不通。

此外，没有理由两次使用几乎相同的代码来获取卸载字符串和显示名称。

尝试

# get a string array of program names
$branding = Get-ChildItem -Path 'HKLM:\Software\DLR\Branding' | Get-ItemProperty | Select-Object -ExpandProperty ProgramName

$regPaths = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall', 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
# get an object array of DisplayName and UninstallStrings
$software = Get-ChildItem -Path $regPaths | Get-ItemProperty | Select-Object DisplayName, UninstallString

# fill the combobox with the (string array) $branding
$objCombobox.Items.AddRange($branding)

$objComboBox.Add_SelectedIndexChanged ({
    $selectme = $objCombobox.SelectedItem
    Write-Host $selectme
    # get the objects that have a displayname like the selected item and write out the matching Uninstall strings
    $software | Where-Object {$_.DisplayName -like "*$selectme*" } | ForEach-Object {
        Write-Host $_.UninstallString
    }
})
