Examples

The following code example shows how to use the OidEnumerator class.

#using <system.dll>

using namespace System;

   String^ InvalidName = "This name is not a valid name";
   String^ InvalidValue = "1.1.1.1.1.1.1.1";
   
   // Create new Oid objects using the specified values.
   // Note that the corresponding Value or Friendly Name property is automatically added to the object.
   Oid ^ o1 = gcnew Oid( Value1 );
   Oid ^ o2 = gcnew Oid( Name1 );
   
   // Create a new Oid object using the specified Value and Friendly Name properties.
   // Note that the two are not compared to determine if the Value is associated 
   //  with the Friendly Name.
   Oid ^ o3 = gcnew Oid( Value2,InvalidName );
   
   //Create a new Oid object using the specified Value. Note that if the value
   //  is invalid or not known, no value is assigned to the Friendly Name property.
   Oid ^ o4 = gcnew Oid( InvalidValue );

   Console::WriteLine( "Oid4: Invalid Value used: {0}, {1} {2}", o4->FriendlyName, o4->Value, Environment::NewLine );
   
   //Create an Oid collection and add several Oid objects.
   OidCollection ^ oc = gcnew OidCollection;
   oc->Add( o1 );
   oc->Add( o2 );
   oc->Add( o3 );
   Console::WriteLine( "Number of Oids in the collection: {0}", oc->Count );
