GAC程序集阅读注册表-C＃

Question

I have an assembly that installed in the GAC. Can this assembly access registry values in HKEY_LOCAL_MACHINE\\SOFTWARE\\COMPANYNAME

I do not get any error but am not able to read subkey from above path. My assembly is strongly signed.

Reason I am using registry is because use of config file is not permitted.

Sample code

string regKey = "HKEY_LOCAL_MACHINE\SOFTWARE\COMPANYNAME";
string userGUID = (string)Registry.GetValue(regKey, "userGUID", "-1");

If you are running 64-bit OS and your assembly is x86, or called by a x86 process, then your registry call is redirected to HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\COMPANYNAME node. This can be the source of your problem.
