Question

我正在使用Powershell从MSI文件中提取信息，我已经找到了这样做的例子，但它们都是特定于值的E，G如果您知道该属性的名称，您可以找到该属性的值我想在哪里找到所有属性，它实际上是我需要的快捷方式表中的信息，下面是我想要实现的内容。

function Get-MsiDatabaseVersion {
param (
    [IO.FileInfo] $FilePath
)

try {
    $windowsInstaller = New-Object -com WindowsInstaller.Installer

    $database = $windowsInstaller.GetType().InvokeMember(
            "OpenDatabase", "InvokeMethod", $Null, 
            $windowsInstaller, @($FilePath.FullName, 0)
        )

    $q = "SELECT Directory_ FROM Shortcut"
    $View = $database.GetType().InvokeMember(
            "OpenView", "InvokeMethod", $Null, $database, ($q)
        )

    $View.GetType().InvokeMember("Execute", "InvokeMethod", $Null, $View, $Null)

    $record = $View.GetType().InvokeMember(
            "Fetch", "InvokeMethod", $Null, $View, $Null
        )

    $productVersion = $record.GetType().InvokeMember(
            "StringData", "GetProperty", $Null, $record, 1
        )

    $View.GetType().InvokeMember("Close", "InvokeMethod", $Null, $View, $Null)

    return $productVersion

} catch {
    throw "Failed to get MSI file version the error was: {0}." -f $_
}

}

Get-MsiDatabaseVersion＆＃34; C：\ Random.msi＆＃34;

所以其中$ q =＆＃34; SELECT Directory_ FROM Shortcut＆＃34;我需要知道快捷方式表中所有行的名称才能找到所有目录。目前它只返回第一个值。如果你能帮助我，我非常感激。谢谢

要了解MSI的属性，您可以在Ocra中打开它。我拿了你的代码并添加了一个循环，请将问题标记为正确，如果它对你有所帮助。

function Get-MsiDatabaseVersion {
param (
    [IO.FileInfo] $FilePath
)

try {
    $windowsInstaller = New-Object -com WindowsInstaller.Installer

    $database = $windowsInstaller.GetType().InvokeMember(
            "OpenDatabase", "InvokeMethod", $Null, 
            $windowsInstaller, @($FilePath.FullName, 0)
        )

    $q = "SELECT Directory_ FROM Shortcut"
    $View = $database.GetType().InvokeMember(
            "OpenView", "InvokeMethod", $Null, $database, ($q)
        )

    $View.GetType().InvokeMember("Execute", "InvokeMethod", $Null, $View, $Null)

    $record = $View.GetType().InvokeMember(
            "Fetch", "InvokeMethod", $Null, $View, $Null
        )

    while($record -ne $null)
    {

        $shortcut = $record.GetType().InvokeMember(
                "StringData", "GetProperty", $Null, $record, 1
            )
        $shortcut

        $record = $View.GetType().InvokeMember(
                "Fetch", "InvokeMethod", $Null, $View, $Null
            )
    }

    $View.GetType().InvokeMember("Close", "InvokeMethod", $Null, $View, $Null)

    #return $shortcut

} catch {
    throw "Failed to get MSI file version the error was: {0}." -f $_
}
}

Get-MsiDatabaseVersion -FilePath .\Setup1.msi

您可能需要查看：

Windows Installer PowerShell Module

作者是MSFT MSI专家，他的cmdlet比使用WindowsInstaller.Installer对象进行COM Interop要清晰得多。

get-msiproperty Product*, UpgradeCode -path example.msi

get-msitable .\example.msi -query "SELECT ComponentId, FileName, File.Attributes FROM Component, File WHERE Component_ = Component" | where-object { $_.'File.Attributes'.HasVital }
