|---|---|---|
![]() | Add(Oid^) | Adds an Oid object to the OidCollection object. |
![]() | CopyTo(array<Oid^>^, Int32) | Copies the OidCollection object into an array. |
![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | GetEnumerator() | Returns an OidEnumerator object that can be used to navigate the OidCollection object. |

![]() ![]() | ICollection::CopyTo(Array^, Int32) | Copies the OidCollection object into an array. |
![]() ![]() | IEnumerable::GetEnumerator() | Returns an OidEnumerator object that can be used to navigate the OidCollection object. |
| Name | Description | |
|---|---|---|
![]() | AsParallel() | Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.) |
![]() | AsQueryable() | Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.) |
![]() | Cast<TResult>() | Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.) |
![]() | OfType<TResult>() | Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.) |
This class implements the ICollection interface.
The following code example shows how to use the OidCollection 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(); }
