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
public class EnumeratorToEnumVariantMarshaler implements ICustomMarshaler
public class EnumeratorToEnumVariantMarshaler implements ICustomMarshaler
Not applicable.

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.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
