CommittableTransaction::BeginCommit Method (AsyncCallback^, Object^)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Begins an attempt to commit the transaction asynchronously.

Namespace:   System.Transactions
Assembly:  System.Transactions (in System.Transactions.dll)

IAsyncResult^ BeginCommit(
	AsyncCallback^ asyncCallback,
	Object^ asyncState


Type: System::AsyncCallback^

The AsyncCallback delegate that is invoked when the transaction completes. This parameter can be null, in which case the application is not notified of the transaction's completion. Instead, the application must use the IAsyncResult interface to check for completion and wait accordingly, or call EndCommit to wait for completion.

Type: System::Object^

An object, which might contain arbitrary state information, associated with the asynchronous commitment. This object is passed to the callback, and is not interpreted by System.Transactions. A null reference is permitted.

Return Value

Type: System::IAsyncResult^

An IAsyncResult interface that can be used by the caller to check the status of the asynchronous operation, or to wait for the operation to complete.

This method returns immediately, before the transaction has been completed. The transaction then commits on a different thread, and the asyncCallback delegate is invoked when it has completed. After this method is called, you do not receive the outcome of the transaction until you call EndCommit.


The commit process may complete synchronously inside this method call.
