以编程方式确定是否安装了COM库（.dll） [英] Programmatically determine if a COM library (.DLL) is installed

问题描述

有没有在C＃编程的方式来确定一个特定的COM DLL是否已安装？或者这是在扫描中的ClassID注册表的问题？

Is there a programmatic way in C# to determine whether a particular COM DLL has been installed? Or is this a matter of scanning the registry for the classId?

推荐答案

我通常做（和会做，如果我需要这再次）是尝试创建你知道一个类是COM库的对象实例 - 无论是进程id或GUID - 并检查故障

What I usually did (and would do, if I needed this again) is try to create an object instance of a class you know is in the COM library - either by ProgID or GUID - and checking for failure.
