参数

  • source
    The source of the error, the object that caused the event.
  • informationCode
    An Integer that identifies the message. This identifier should be unique when combined with the source parameter, so the source and informationCode combination should be unique. However, the informationCode alone is not expected to be unique.
  • subComponent
    An arbitrary string that identifies the sub-module within a source. For example, the transform in a Pipeline task.
  • description
    Text of the message.
  • helpFile
    The path to the help file containing detailed information.
  • helpContext
    Identifier of the topic in the Help file.
  • idofInterfaceWithError
    A textual representation of the GUID of the interface that caused the error.
  • fireAgain
    A Boolean that indicates this should continue firing or stop firing. A value of true indicates that it should continue firing.

备注

Compared to a warning, the informational event communicates important information that does not necessarily denote any data loss or other cause for concern. However, it is important enough that it warrants more than a log entry.
