如何在 Vista 中读取注册表分支 HKEY_LOCAL_MACHINE? [英] How to read registry branch HKEY_LOCAL_MACHINE in Vista?

问题描述

我将应用程序设置存储在 HKEY_LOCAL_MACHINE\SOFTWARE\MyCompany 分支下.不同用户的设置必须相同，这就是设置不在 HKEY_CURRENT_USER 下的原因.注册表值仅在应用程序使用期间读取.

I have Application settings stored under HKEY_LOCAL_MACHINE\SOFTWARE\MyCompany branch. Settings must be same for different users and that is the reason why settings are not under HKEY_CURRENT_USER. Registry values are only read during use of application.

现在，在 Windows Vista 中，由于 UAC，您不能再使用以下代码读取注册表值:

Now, in Windows Vista and due to UAC you can't anymore use following code to read registry values:

RegistryKey myKey = Registry.LocalMachine.CreateSubKey
        ("SOFTWARE\\MyCompany\\MyAppName");

如何从我的代码 (C#) 中的 LocalMachine 分支读取值?

How can I read the values from LocalMachine branch in my code (C#)?

推荐答案

问题是您正在尝试创建一个未读取的密钥.如果您使用适当的 API，您应该能够在 Vista 上从 HKLM 读取值.

The problem is that you are trying to create a key not read it. You should be able to read values from HKLM just fine on Vista if you use the appropriate API.

RegistryKey myKey = Registry.LocalMachine.OpenSubKey(
  @"Software\MyCompany\MyAppName", 
  false);

注意上面的 false 参数.这具有以只读模式打开密钥的效果.这是 OpenSubKey 的默认设置，但我更喜欢显式设置(主要是因为我不记得默认设置).

Notice the false parameter in the above. This has the effect of opening the key in a read only mode. This is the default setting for OpenSubKey but I prefer to be explicit (mainly because I can't ever remember the default).
