已安装应用程序列表的代码提供错误结果 [英] Code for List of installed Applications is Giving Wrong Result

问题描述

我使用下面的代码获取Windows中已安装程序的列表。

此代码完美运行在我的32位Windows 7机器上，但是在我的Windows 8 64位机器上，它获得了一个应用程序列表但不完整或不正确。

Hi,

I am using the code below to get the list of installed programs in windows.
This code is working perfectly in my 32 Bit Windows 7 machine, but on my Windows 8 64 bit machine, it is getting a list of applications but not incomplete or incorrect.

RegistryKey baseRegistryKey = Registry.LocalMachine;
string subKey = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall";
RegistryKey uninstallKey = baseRegistryKey.OpenSubKey(subKey);
string[] allApplications = uninstallKey.GetSubKeyNames();

有人可以帮我弄清楚机器可能出了什么问题吗？

Can somebody help me figure out what might be wrong with the machine?

推荐答案

这里有一个类似的问题：如何从Windows 64位中的注册表中检索应用程序列表 [ ^ ]

它明显分享：

这是因为注册表重定向 [ ^ ]。



具体来说，有一个包含注册表项的Wow6432Node s用于64位操作系统上的32位进程（ WOW64 [ ^ ]）。



见这个MSDN [ ^ ]文章了解更多信息。

另见所以 [ ^ ] thread。



另一个Microsoft支持网站用类似的方式讨论如何存储密钥：如何使用64位版本的Win查看系统注册表dows [ ^ ]

A similar question here: How to retrieve list of applications from registry in Windows 64 bit[^]
It clearly shares:
This is because of registry redirection[^].

Specifically, there is a Wow6432Node that contains registry keys for 32-bit processes on a 64-bit OS (WOW64[^]).

See this MSDN[^] article for more information.
