OidEnumerator Class
Visual Studio 2010
Provides the ability to navigate through an OidCollection object. This class cannot be inherited.
Assembly: System (in System.dll)
The OidEnumerator type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | MoveNext | Advances to the next Oid object in an OidCollection object. |
![]() | Reset | Sets an enumerator to its initial position. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
This class implements the IEnumerator interface.
The following code example shows how to use the OidEnumerator class.
#using <system.dll> using namespace System; using namespace System::Security::Cryptography; int main() { // Assign values to strings. String^ Value1 = "1.2.840.113549.1.1.1"; String^ Name1 = "3DES"; String^ Value2 = "1.3.6.1.4.1.311.20.2"; 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 ); //Write out the property information of the Oid objects. Console::WriteLine( "Oid1: Automatically assigned Friendly Name: {0}, {1}", o1->FriendlyName, o1->Value ); Console::WriteLine( "Oid2: Automatically assigned Value: {0}, {1}", o2->FriendlyName, o2->Value ); Console::WriteLine( "Oid3: Name and Value not compared: {0}, {1}", o3->FriendlyName, o3->Value ); 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 ); Console::WriteLine( "Is synchronized: {0} {1}", oc->IsSynchronized, Environment::NewLine ); //Create an enumerator for moving through the collection. OidEnumerator ^ oe = oc->GetEnumerator(); //You must execute a MoveNext() to get to the first item in the collection. oe->MoveNext(); // Write out Oids in the collection. Console::WriteLine( "First Oid in collection: {0},{1}", oe->Current->FriendlyName, oe->Current->Value ); oe->MoveNext(); Console::WriteLine( "Second Oid in collection: {0},{1}", oe->Current->FriendlyName, oe->Current->Value ); //Return index in the collection to the beginning. oe->Reset(); }
