参数
- connection
- DbConnection
连接。
- eventData
- ConnectionEventData
有关连接的上下文信息。
- result
- InterceptionResult
表示当前结果(如果存在)。
如果某个以前的侦听器通过调用 Suppress()来禁止执行,则此值已IsSuppressed设置为 true
。
此值通常用作此方法实现的返回值。
返回
如果 IsSuppressed 为 false
,则 EF 将照常继续。
如果 IsSuppressed 为 true
,则 EF 将取消它要执行的操作。
对于任何未尝试取消该操作的侦听器,此方法的实现是返回 result
传入的值。
