DbTransaction.cs

Asynchronously rolls back a transaction from a pending state.

public virtual System.Threading.Tasks.Task RollbackAsync (System.Threading.CancellationToken cancellationToken = default);
abstract member RollbackAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task
override this.RollbackAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Overridable Function RollbackAsync (Optional cancellationToken As CancellationToken = Nothing) As Task

Parameters

cancellationToken
CancellationToken

An optional token to cancel the asynchronous operation. The default value is None.

Returns

A task representing the asynchronous operation.

Exceptions

The cancellation token was canceled. This exception is stored into the returned task.

Remarks

The default implementation of this asynchronous method delegates to its synchronous counterpart and returns a completed Task, potentially blocking the calling thread.

Data providers that support asynchronous programming should override the default implementation using asynchronous I/O operations.

This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by Rollback().
