Help me convert this line to C#

Please help me convert this line to C#.

objManagementBaseObject.SetPropertyValue("hDefKey", CType("&H" &
Hex(RegistryHive.LocalMachine), Long))

Related References in C#: System.Management

Thank you.

Additional Info:

Code was originally in VB.

From stackoverflow

• It looks like RegistryHive.LocalMachine is just an enum value, in which case passing it through Hex() is just a waste of time:

  objManagmentBaseObject.SetPropertyValue("hDefKey", (long)RegistryHive.LocalMachine);
  

  Ishmael : Thanks. I realized it after walking away from the code that the VB line is just trying to typecast it to long.

  Joel Coehoorn : I suspect the code was originally written in VB without any casting at all, and the ugly Enum -> Hex -> String -> Object -> Long process was added because in certain cases the wrong conversion was happening. That's the more-charitable way you find this kind of code

• objManagementBaseObject.SetPropertyValue("hDefKey", (long)RegistryHive.LocalMachine);
  

  is the C# equivalent to the VB.NET line.

  Thanks for the insight!
