Question

我尝试从ProductCode或CustomAction等MSI文件中提取一些信息。我已经使用了互联网上的其他脚本并对其进行了编辑，但我的脚本存在一些问题。

这只是原始代码的一小部分，但如果我执行此代码，则会收到以下错误消息：

警告：异常调用＆＃34; InvokeMember＆＃34;用＆＃34; 5＆＃34;参数：＆＃34; OpenView，Sql＆＃34;

function Get-MSIFileInformationList {

MSI数据库不支持LIKE，因为它只实现了SQL语言的一个子集（https://msdn.microsoft.com/en-us/library/windows/desktop/aa372021.aspx）。这应该有效：

$Query = "SELECT $SELECT FROM $FROM WHERE $WHERE = 'ProductName'"

如果您需要过滤，则必须对SELECT * FROM Property的结果进行过滤。
