public IAsyncResult BeginGetMessage( int sequenceNumber, string fileName, long remoteOffset, int length, AsyncCallback callback, Object state ) |
Parameters
- sequenceNumber
- Type: System..::..Int32
Message sequence number.
- fileName
- Type: System..::..String
The path of the local file. This cannot be a directory.
- remoteOffset
- Type: System..::..Int64
The starting offset of the message data to download.
- length
- Type: System..::..Int32
Number of bytes to transfer or -1 to transfer all data until an end of message is reached.
- callback
- Type: System..::..AsyncCallback
An optional asynchronous callback to be called when the operation is complete.
- state
- Type: System..::..Object
A user-provided object that identifies this particular asynchronous operation.
Return Value
An IAsyncResult that references the asynchronous operation.Remarks
Uses IMAP FETCH command to retrieve the message.
By default, this method marks the message as read. To prevent this behavior, set the UsePeekForGetMessage to true.
In builds for .NET 4.0 and higher, this method is available as an extension method. Add 'using Rebex.Legacy' (C#) or 'Import Rebex.Legacy' (VB.NET) to your code in order to use it.
