注册表项获取值返回NULL [英] Registry Key Get Value returns NULL

问题描述

为什么以下代码为 shellValue 返回NULL?

Why does the following code return NULL for shellValue?

        string shellValue;
        RegistryKey shellKey = Registry.LocalMachine;
        shellKey = shellKey.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", true);
        shellValue = shellKey.GetValue("Shell") as string;

我确实具有管理员权限.

I do have Administrator privileges.

推荐答案

您实际上正在获得此子项"HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ Shell".这是因为某些密钥是通过WOW64重定向的.检查此以获取更多信息.

You are actually getting this subkey "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell". This is because some keys are redirected by WOW64. Check this for more info.

请尝试以下操作:

string shellValue;
RegistryKey shellKey = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry64);;
shellKey = shellKey.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", true);
shellValue = shellKey.GetValue("Shell") as string;
