How to add an application into context menu for any user using c# code. I used this solution.

RegistryKey _key = Registry.ClassesRoot.OpenSubKey($"HKEY_CLASSES_ROOT\\Directory\\Background\\shell", true);
RegistryKey newkey = _key.CreateSubKey("Use Virtual Printer");

RegistryKey subNewkey = newkey.CreateSubKey("Command");
subNewkey.SetValue("", "C:\\yourApplication.exe");
subNewkey.Close();

newkey.Close();
_key.Close();

But I got Null Reference Exception in second line.

Are you running your program with administrator rights? These are required to get writeable access to this registry path. – Florian Berger Feb 26 '18 at 05:53
no. How can i change this in a way so any user can get this – kaushalya perera Feb 26 '18 at 05:54
i should use **HKEY_CURRENT_USER\Software\Classes\directory\shell** for any user. right? – kaushalya perera Feb 26 '18 at 05:57
That's current user only. Have to take in account that operation may fail due permissions. also, look at this https://stackoverflow.com/questions/13728491/opensubkey-returns-null-for-a-registry-key-that-i-can-see-in-regedit-exe – Swift - Friday Pie Feb 26 '18 at 05:57
