Releases the resources used by the AttachmentBase.
Assembly: System (in System.dll)
Call Dispose when you are finished using the AttachmentBase. The Dispose method leaves the AttachmentBase in an unusable state. After calling Dispose, you must release all references to the AttachmentBase so the garbage collector can reclaim the memory that the AttachmentBase was occupying. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.
Note Always call Dispose before you release your last reference to the AttachmentBase. Otherwise, the resources it is using will not be freed until the garbage collector calls the AttachmentBase object's Finalize method.
