C# 32位程序訪問64位注冊表

接上文：http://www.cnblogs.com/TaiYangXiManYouZhe/p/5086974.html

上代碼：

RegistryKey localKey;
if (Environment.Is64BitOperatingSystem)
   localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64);
else
   localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32);

string value = localKey.OpenSubKey(@"SOFTWARE\Microsoft\Office\15.0\Common\InstallRoot").GetValue("Path").ToString();

 

 

很簡單，首先，Environment.Is64BitOperatingSystem 判斷是否是64位的操作系統。

然后通過注冊表打開目錄時，傳入相應的RegistryView枚舉即可。注意：打開注冊表時，調用的是OpenBaseKey方法！
