Provides the managed definition of the STGMEDIUM structure.

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

public struct STGMEDIUM

The STGMEDIUM type exposes the following members.

Public methodEqualsIndicates whether this instance and a specified object are equal. (Inherited from ValueType.)
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 methodGetHashCodeReturns the hash code for this instance. (Inherited from ValueType.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)

Public fieldpUnkForReleaseRepresents a pointer to an interface instance that allows the sending process to control the way the storage is released when the receiving process calls the ReleaseStgMedium function. If pUnkForRelease is null, ReleaseStgMedium uses default procedures to release the storage; otherwise, ReleaseStgMedium uses the specified IUnknown interface.
Public fieldtymedSpecifies the type of storage medium. The marshaling and unmarshaling routines use this value to determine which union member was used. This value must be one of the elements of the TYMED enumeration.
Public fieldunionmemberRepresents a handle, string, or interface pointer that the receiving process can use to access the data being transferred.

The common language runtime throws an exception when a COM method in native code returns an HRESULT. For more information, see How to: Map HRESULTs and Exceptions.
