How to restore the registry value to "value not set"

Please view the page above.

I use the RegistryKey.SetValue("",""), but it set the value to null string, how to restore to "value not set"?

I cannot delete the key and re-create the key.

In case of default values, try key.DeleteValue("").

Did you try passing Nothing instead of an empty string? The value parameter is an Object type so Nothing should be an acceptable value.

Sorry, the error is "value can not be null" to use SetValue("", Nothing).

OK, sorry, I see now that a value of null will throw an exception.

You have to use the DeleteValue() method to get "value not set".
