The ASN.1 NULL type is converted into to a C# class that inherits the Asn1Null run-time class. This base class does not contain a public member variable for a value because the NULL type has no associated value.

The following shows the basic mapping from ASN.1 type to C# class definition:

<name> ::= NULL

   public class <name> : Asn1Null {
   public <name> () :
      base() {
   }
}

This shows the class generated for a simple NULL assignment. If a tagged type is specified, specific encode and decode methods will be generated as well.
