Question

I have created the following registry key (copied through regedit):

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\test

I would like to now delete this registry key, and so… I have been using the following code and am running into a small error.

RegistryKey regKey;

    string regPath_Key = @"Software\Microsoft\Windows\CurrentVersion\test";

    regKey = Registry.CurrentUser.OpenSubKey(regPath_Key, true);

    if(regKey != null)   // Always returns null, even though the key does exist.
    {
        Registry.CurrentUser.DeleteSubKey(regPath_Key, true);
    }

The issue I am having is that the line if(regKey != null) always returns null! I have gone back and checked that the key does in fact exist multiple times – but still the same result. I am going to assume my code has issues somewhere?

You should not include HKEY_CURRENT_USER in the string you pass to Registry.CurrentUser.OpenSubKey(). Instead use

string regPath_Key = @"Software\Microsoft\Windows\CurrentVersion\test";
