Use the return value of this method to evaluate whether the report is set to be cached. If the value is false, the method returns a nullnull 引用（在 Visual Basic 中为 Nothing） (or Nothing in Visual Basic) for Item.
Use GetCacheOptions only if the execution option is configured to run on demand. For more information about the cache settings of a report, see 缓存报表 (SSRS). For information about programmatically setting the caching options of a report, see SetCacheOptions method.
