LogRecordSequence.EndAppend(IAsyncResult) Method


Ends an asynchronous append operation. This method cannot be inherited.

 virtual System::IO::Log::SequenceNumber EndAppend(IAsyncResult ^ result);
public System.IO.Log.SequenceNumber EndAppend (IAsyncResult result);
abstract member EndAppend : IAsyncResult -> System.IO.Log.SequenceNumber
override this.EndAppend : IAsyncResult -> System.IO.Log.SequenceNumber
Public Function EndAppend (result As IAsyncResult) As SequenceNumber



A reference to the outstanding asynchronous I/O request.


The sequence number of the appended log record.



result is invalid.

The request could not be performed because of an unexpected I/O exception.


The request could not be performed because of an I/O device error.

End has already been called for this asynchronous operation.

The operation cannot be performed because the record sequence was opened with read-only access.

The method was called after the sequence has been disposed of.

There is not enough memory to continue the execution of the program.

The record sequence is full.

Access for the specified log sequence is denied by the operating system.


This method blocks until the I/O operation has completed. Errors that occur during an asynchronous write request, such as a disk failure during the I/O request, become visible when EndAppend is called.

This method must be called exactly once on every IAsyncResult returned by the BeginAppend method.
