EnumerableToDispatchMarshaler Class

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

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

public class EnumerableToDispatchMarshaler : ICustomMarshaler
public class EnumerableToDispatchMarshaler implements ICustomMarshaler
public class EnumerableToDispatchMarshaler implements ICustomMarshaler

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.
