System.Runtime.InteropServices.ComTypes Namespace

.NET Framework 4.5

The System.Runtime.InteropServices.ComTypes namespace contains methods that are defintions of COM functions for managed code. These functions replace the now-obsolete UCOM* methods in the System.Runtime.InteropServices namespace.

Structures

	Structure	Description
	BIND_OPTS	Stores the parameters that are used during a moniker binding operation.
	BINDPTR	Contains a pointer to a bound-to FUNCDESC structure, VARDESC structure, or an ITypeComp interface.
	CONNECTDATA	Describes a connection that exists to a given connection point.
	DISPPARAMS	Contains the arguments passed to a method or property by IDispatch::Invoke.
	ELEMDESC	Contains the type description and process transfer information for a variable, function, or a function parameter.
	ELEMDESC.DESCUNION	Contains information about an element.
	EXCEPINFO	Describes the exceptions that occur during IDispatch::Invoke.
	FILETIME	Represents the number of 100-nanosecond intervals since January 1, 1601. This structure is a 64-bit value.
	FORMATETC	Represents a generalized Clipboard format.
	FUNCDESC	Defines a function description.
	IDLDESC	Contains information needed for transferring a structure element, parameter, or function return value between processes.
	PARAMDESC	Contains information about how to transfer a structure element, parameter, or function return value between processes.
	STATDATA	Provides the managed definition of the STATDATA structure.
	STATSTG	Contains statistical information about an open storage, stream, or byte-array object.
	STGMEDIUM	Provides the managed definition of the STGMEDIUM structure.
	TYPEATTR	Contains attributes of a UCOMITypeInfo.
	TYPEDESC	Describes the type of a variable, return type of a function, or the type of a function parameter.
	TYPELIBATTR	Identifies a particular type library and provides localization support for member names.
	VARDESC	Describes a variable, constant, or data member.
	VARDESC.DESCUNION	Contains information about a variable.

Interfaces

	Interface	Description
	IAdviseSink	Provides a managed definition of the IAdviseSink interface.

	IPersistFile	Provides the managed definition of the IPersistFile interface, with functionality from IPersist.
	IRunningObjectTable	Provides the managed definition of the IRunningObjectTable interface.
	IStream	Provides the managed definition of the IStream interface, with ISequentialStream functionality.
	ITypeComp	Provides the managed definition of the ITypeComp interface.
	ITypeInfo	Provides the managed definition of the Component Automation ITypeInfo interface.
	ITypeInfo2	Provides the managed definition of the ITypeInfo2 interface.
	ITypeLib	Provides the managed definition of the ITypeLib interface.
	ITypeLib2	Provides a managed definition of the ITypeLib2 interface.

Enumerations

	Enumeration	Description
	ADVF	Specifies the requested behavior when setting up an advise sink or a caching connection with an object.
	CALLCONV	Identifies the calling convention used by a method described in a METHODDATA Data Type structure.
	DATADIR	Specifies the direction of the data flow in the dwDirection parameter of the EnumFormatEtc method. This determines the formats that the resulting enumerator can enumerate.
	DESCKIND	Identifies the type description being bound to.
	DVASPECT	Specifies the desired data or view aspect of the object when drawing or getting data.
	FUNCFLAGS	Identifies the constants that define the properties of a function.
	FUNCKIND	Defines how to access a function.
	IDLFLAG	Describes how to transfer a structure element, parameter, or function return value between processes.
	IMPLTYPEFLAGS	Defines the attributes of an implemented or inherited interface of a type.
	INVOKEKIND	Specifies how to invoke a function by IDispatch::Invoke.
	LIBFLAGS	Defines flags that apply to type libraries.
	PARAMFLAG	Describes how to transfer a structure element, parameter, or function return value between processes.
	SYSKIND	Identifies the target operating system platform.
