The ASN.1 OBJECT IDENTIFIER type is converted to a C# class that inherits the Asn1ObjectIdentifier run-time class. This base class encapsulates the following public member variable:

 public int[] mValue;

The number of subidentifiers to be encoded or that were decoded is specified in the built-in length component of the array object (i.e., mValue.length).

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

<name> ::= OBJECT IDENTIFIER

 public class <name> : Asn1ObjectIdentifier {
 public <name> () :
 base() {
 }
 public <name> (int[] value_) :
 base (value_) {
 }
}

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