Registry Reading

[Midol]

Keep getting an error on this code:

            RegistryKey rKey = Registry.LocalMachine;
            rKey.OpenSubKey(@"\SOFTWARE\Blizzard Entertainment\World of Warcraft", true);
            try
            {
                return rKey.GetValue("InstallPath").ToString();
            }
            catch (NullReferenceException)
            {
                return null;
            }

I KNOW for certain that a key exists in this location, so the key not existing is out of the question.

Unsure what the issue could be.

ETA: Obviously the error no longer appears due to the catch, but that should have been obvious.

Try the following way :
RegistryKey rkey;
rkey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Blizzard Entertainment\World of Warcraft",true);

also , try Convert.ToString function in the return snippet

That's because you set rKey = HKLM key, and certainly the HKLM doesn't contain the subkey "InstallPath", so when you try to call ToString on rKey.GetValue("InstallPath"), you get null exeception. Pirate's code should work.

Thanks guys.

I must not have been following the tutorial properly

All working.
