UseTransactionAsync(DbTransaction, Guid, CancellationToken)

Source:

RelationalConnection.cs

指定用于数据库操作的现有 DbTransaction 。

public virtual System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Storage.IDbContextTransaction?> UseTransactionAsync (System.Data.Common.DbTransaction? transaction, Guid transactionId, System.Threading.CancellationToken cancellationToken = default);

abstract member UseTransactionAsync : System.Data.Common.DbTransaction * Guid * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Storage.IDbContextTransaction>
override this.UseTransactionAsync : System.Data.Common.DbTransaction * Guid * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Storage.IDbContextTransaction>

Public Overridable Function UseTransactionAsync (transaction As DbTransaction, transactionId As Guid, Optional cancellationToken As CancellationToken = Nothing) As Task(Of IDbContextTransaction)

参数

transaction

DbTransaction

要使用的事务。

transactionId

Guid

事务的唯一标识符。

cancellationToken

CancellationToken

等待 CancellationToken 任务完成时要观察的 。

返回

Task<IDbContextTransaction>

包装所提供的事务的 实例 IDbTransaction 。

实现

UseTransactionAsync(DbTransaction, Guid, CancellationToken)

例外

OperationCanceledException

如果已取消 CancellationToken。
