EnumerableToDispatchMarshaler Class

Definition

Marshals the COM IDispatch interface to the .NET Framework IEnumerable interface, and vice versa.

public ref class EnumerableToDispatchMarshaler : System::Runtime::InteropServices::ICustomMarshaler
public class EnumerableToDispatchMarshaler : System.Runtime.InteropServices.ICustomMarshaler
type EnumerableToDispatchMarshaler = class
    interface ICustomMarshaler
Public Class EnumerableToDispatchMarshaler

Remarks

This custom marshaler marshals IDispatch to IEnumerable and marshals IEnumerable to IDispatch when a member with a DISPID of -4 exists. When you use the Type Library Importer (Tlbimp.exe) to create a class that implements IEnumerable , the CLR uses this custom marshaler automatically to bridge COM enumerators and .NET enumerators. Calling GetEnumerator results in IDispatch.Invoke being called with a DISPID of -4, and vice versa.
