CommittableTransaction.BeginCommit Method

Note: This method is new in the .NET Framework version 2.0.

Begins an attempt to commit the transaction asynchronously.

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

public IAsyncResult BeginCommit (
	AsyncCallback asyncCallback,
	Object asyncState
public IAsyncResult BeginCommit (
	AsyncCallback asyncCallback, 
	Object asyncState
public function BeginCommit (
	asyncCallback : AsyncCallback, 
	asyncState : Object
) : IAsyncResult



The AsyncCallback delegate that is invoked when the transaction completes. This parameter can be a null reference (Nothing in Visual Basic), 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.


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

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.
