Finding if registry key exists HKEY_CLASSES_ROOT\CLSID\{3BDAAC43-E734-11D5-93AF-00105A990292}

Question

I have a bool function that checks for the existence of a registry key:

  private bool KeyExists(RegistryKey RootKey, string subKeyName)
    {
        RegistryKey ret = RootKey.OpenSubKey(subKeyName);
        if (ret == null)  {return false;}
        else { return true; }
    }

In my code,

if (!KeyExists(Registry.ClassesRoot, (@"\CLSID\{3BDAAC43-E734-11D5-93AF-00105A990292}")))
    {
            //create the subkey;
    }

The key, copied from regedit is

HKEY_CLASSES_ROOT\CLSID\{3BDAAC43-E734-11D5-93AF-00105A990292}

Even though the key exists, the function, KeyExists() always returns false.

If I replace the call to KeyExists() thusly:

            if (!KeyExists(Registry.LocalMachine, (@"SOFTWARE\Microsoft\")))

The function returns true.

Unlike all the examples I've found here and elsewhere, I'm checking for a CLSID and I'm pretty sure I'm not passing the parameter correctly.

The following may be helpful: https://stackoverflow.com/a/72654434/10024425 - it's VB.NET, but should be easy to convert. — Tu deschizi eu inchid, Jan 17 '23 at 03:22
It's good that you have a version that works and a version that doesn't. That way, you can compare them to look for any differences. For example, the one that doesn't work begins with an extra ``\``. — Raymond Chen, Jan 17 '23 at 04:19
