System.Runtime.InteropServices.Marshalling Namespace

Contains support types for source-generated interop, such as MarshalUsingAttribute.

Classes

AnsiStringMarshaller	Marshaller for ANSI strings.
ArrayMarshaller<T,TUnmanagedElement>	Represents a marshaller for arrays.
BStrStringMarshaller	Marshaller for BSTR strings.
ComExposedClassAttribute<T>	Indicates that a type's instances should be exposed to COM.
ComInterfaceMarshaller<T>	Marshals a COM interface using a StrategyBasedComWrappers instance.
ComObject	Base class for all COM source-generated runtime callable wrappers (RCWs).
ContiguousCollectionMarshallerAttribute	Specifies that this marshaller entry-point type is a contiguous collection marshaller.
CustomMarshallerAttribute	Indicates an entry point type for defining a marshaller.
ExceptionAsDefaultMarshaller<T>	Converts the exception to the default value of the specified unmanaged type.
ExceptionAsHResultMarshaller<T>	Marshals an exception object to the value of its HResult converted to T.
ExceptionAsNaNMarshaller<T>	Converts all exceptions to NaN.
ExceptionAsVoidMarshaller	Represents a marshaller that swallows exceptions.
GeneratedComClassAttribute	Specifies that the attributed type will be exposed to COM through source-generated COM and that the source generator should generate code for it.
GeneratedComInterfaceAttribute	Specifies that the attributed type is a COM interface and that the source generator should generate code for it.
IUnknownDerivedAttribute<T,TImpl>	Indicates that an interface is a managed representation of an IUnknown-derived interface.
MarshalUsingAttribute	Attribute used to provide a custom marshaller type or size information for marshalling.
NativeMarshallingAttribute	Attribute used to provide a default custom marshaller type for a given managed type.
PointerArrayMarshaller<T,TUnmanagedElement>	Represents a marshaller for an array of pointers.
ReadOnlySpanMarshaller<T,TUnmanagedElement>.UnmanagedToManagedOut	Supports marshalling from managed into unmanaged in a call from unmanaged code to managed code.
ReadOnlySpanMarshaller<T,TUnmanagedElement>	Supports marshalling a ReadOnlySpan<T> from managed value to a contiguous native array of the unmanaged values of the elements.
SafeHandleMarshaller<T>	Marshals SafeHandle-derived types following the lifetime rules for SafeHandle objects.
SpanMarshaller<T,TUnmanagedElement>	Supports marshalling a Span<T> from managed value to a contiguous native array of the unmanaged values of the elements.
StrategyBasedComWrappers	A ComWrappers-based type that uses customizable strategy objects to implement COM object wrappers and managed object wrappers exposed to COM.
UniqueComInterfaceMarshaller<T>	Marshals COM interfaces using a StrategyBasedComWrappers instance that only creates unique native object wrappers (RCWs).
Utf16StringMarshaller	A marshaller for UTF-16 strings.
Utf8StringMarshaller	A marshaller for UTF-8 strings.

Structs
