TypeToTypeInfoMarshaler Class

Marshals the unmanaged ITypeInfo interface to the managed Type class, and marshals the managed Type class to the unmanaged ITypeInfo interface.

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

public class TypeToTypeInfoMarshaler : ICustomMarshaler

The ITypeInfo interface exposed for a .NET type is based on the metadata that would appear in an exported type library. Likewise, the Type instance exposed for an ITypeInfo interface is based on the metadata that would appear in an imported assembly.

The Type Library Importer (Tlbimp.exe) marks ITypeInfo parameters with the appropriate MarshalAsAttribute with the CustomMarshaler enumeration member when converting signatures that use ITypeInfo parameters to signatures that use Type parameters.

The same conversion functionality can be accomplished without the custom marshaler, by calling GetITypeInfoForType and GetTypeForITypeInfo.


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