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<DbTransaction>
ValueTask<DbTransaction>

， Task 其中包含將做為傳遞至 RelationalDatabaseFacadeExtensions.UseTransactionAsync 此方法之有效值的值，用於未嘗試變更結果的任何攔截器的實作，通常是使用 傳回 result 傳入的值 FromResult<TResult>(TResult)

例外狀況

OperationCanceledException

如果取消 CancellationToken。
