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

public ref class EnumeratorToEnumVariantMarshaler : System::Runtime::InteropServices::ICustomMarshaler

public class EnumeratorToEnumVariantMarshaler : System.Runtime.InteropServices.ICustomMarshaler

type EnumeratorToEnumVariantMarshaler = class
    interface ICustomMarshaler

Public Class EnumeratorToEnumVariantMarshaler
Implements ICustomMarshaler

Inheritance: Object
EnumeratorToEnumVariantMarshaler

Implements: ICustomMarshaler

Remarks

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.

Constructors

EnumeratorToEnumVariantMarshaler()

Provides the static class constructor.
