EnumeratorToEnumVariantMarshaler Class

Marshals the COM IEnumVARIANT interface to the .NET Framework IEnumerator interface, and vice versa.


Namespace:  System.Runtime.InteropServices.CustomMarshalers
Assembly:  CustomMarshalers (in CustomMarshalers.dll)

public class EnumeratorToEnumVariantMarshaler : ICustomMarshaler

The EnumeratorToEnumVariantMarshaler type exposes the following members.

Public methodCleanUpManagedDataPerforms necessary cleanup of the managed data when it is no longer needed.
Public methodCleanUpNativeDataPerforms necessary cleanup of the unmanaged data when it is no longer needed.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodStatic memberGetInstanceReturns an instance of the custom marshaler.
Public methodGetNativeDataSizeReturns the size in bytes of the unmanaged data to be marshaled.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodMarshalManagedToNativeMarshals an object from managed code to unmanaged code.
Public methodMarshalNativeToManagedMarshals an object from unmanaged code to managed code.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

This custom marshaler marshals IEnumVARIANT to IEnumerator and marshals IEnumerator to IEnumVARIANT. The CLR automatically uses this class to bridge COM enumerators and .NET enumerators. The IEnumerator type returned by the GetEnumerator method in the imported COM class uses EnumeratorToEnumVariantMarshaler to map the calls to the IEnumVARIANT interface pointer returned by the COM object's member with a DISPID of -4.
