DbTransactionInterceptor.TransactionUsedAsync 方法

定义

调用 后 RelationalDatabaseFacadeExtensions.UseTransactionAsync 立即调用 。

public virtual System.Threading.Tasks.Task<System.Data.Common.DbTransaction> TransactionUsedAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData eventData, System.Data.Common.DbTransaction result, System.Threading.CancellationToken cancellationToken = default);
public virtual System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction> TransactionUsedAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData eventData, System.Data.Common.DbTransaction result, System.Threading.CancellationToken cancellationToken = default);
abstract member TransactionUsedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Common.DbTransaction>
override this.TransactionUsedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Common.DbTransaction>
abstract member TransactionUsedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction>
override this.TransactionUsedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction>
Public Overridable Function TransactionUsedAsync (connection As DbConnection, eventData As TransactionEventData, result As DbTransaction, Optional cancellationToken As CancellationToken = Nothing) As Task(Of DbTransaction)
Public Overridable Function TransactionUsedAsync (connection As DbConnection, eventData As TransactionEventData, result As DbTransaction, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of DbTransaction)

参数

connection
DbConnection

连接。

eventData
TransactionEventData

有关连接和事务的上下文信息。

result
DbTransaction

DbTransaction传递给 的 RelationalDatabaseFacadeExtensions.UseTransactionAsync。 此值通常用作此方法实现的返回值。

cancellationToken
CancellationToken

等待 CancellationToken 任务完成时要观察的 。

返回

一个 Task 包含将用作有效值的值,该值传递给 RelationalDatabaseFacadeExtensions.UseTransactionAsync 任何未尝试更改结果的侦听器的此方法的正常实现是返回 result 传入的值,通常使用 FromResult<TResult>(TResult)

实现

例外
