參數
- connection
- DbConnection
連接。
- eventData
- TransactionEventData
連線和交易的相關內容資訊。
- result
- DbTransaction
DbTransaction傳遞至 RelationalDatabaseFacadeExtensions.UseTransactionAsync 的 。 這個值通常用來做為這個方法實作的傳回值。
- cancellationToken
- CancellationToken
CancellationToken等候工作完成時要觀察的 。
傳回
, Task 其中包含將做為傳遞至 RelationalDatabaseFacadeExtensions.UseTransactionAsync 此方法之一般實作之有效值的值,用於未嘗試變更結果的任何攔截器,通常是使用 傳回 result
傳入的值 FromResult<TResult>(TResult)
