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 TypeToTypeInfoMarshaler type exposes the following members.

Public methodCleanUpManagedDataPerforms necessary cleanup of the managed data when it is no longer needed.
Public methodCleanUpNativeDataPerforms necessary cleanup of the unmanaged data when it is no longer needed.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodStatic memberGetInstanceReturns an instance of the custom marshaler.
Public methodGetNativeDataSizeReturns the size in bytes of the unmanaged data to be marshaled.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodMarshalManagedToNativeMarshals an object from managed code to unmanaged code.
Public methodMarshalNativeToManagedMarshals an object from unmanaged code to managed code.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

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.
