DbTransaction.RollbackAsync Method

Definition

Namespace:

System.Data.Common

Assemblies:

netstandard.dll, System.Data.Common.dll

Overloads

RollbackAsync(CancellationToken)	Asynchronously rolls back a transaction from a pending state.
RollbackAsync(String, CancellationToken)	Rolls back all commands that were executed after the specified savepoint was established.

RollbackAsync(CancellationToken)

Source:

DbTransaction.cs

Asynchronously rolls back a transaction from a pending state.

C#

public virtual System.Threading.Tasks.Task RollbackAsync(System.Threading.CancellationToken cancellationToken = default);

Parameters

cancellationToken

CancellationToken

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

Returns

Task

A task representing the asynchronous operation.

Exceptions

OperationCanceledException

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().

RollbackAsync(String, CancellationToken)

Source:

DbTransaction.cs

Rolls back all commands that were executed after the specified savepoint was established.

C#

public virtual System.Threading.Tasks.Task RollbackAsync(string savepointName, System.Threading.CancellationToken cancellationToken = default);

Parameters

savepointName

String

The name of the savepoint to roll back to.

cancellationToken

CancellationToken

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

Returns

Task

A Task representing the asynchronous operation.

Exceptions

OperationCanceledException

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

Remarks

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(String).
