VirtualSocket.BeginSend Method

Sends data asynchronously to a connected VirtualSocket.

[Visual Basic]
Overridable Public Function BeginSend( _
   ByVal buffer As Byte(), _
   ByVal offset As Integer, _
   ByVal size As Integer, _
   ByVal socketFlags As SocketFlags, _
   ByVal callback As AsyncCallback, _
   ByVal state As Object _
) As IAsyncResult

[C#]
public virtual IAsyncResult BeginSend(
   byte[] buffer,
   int offset,
   int size,
   SocketFlags socketFlags,
   AsyncCallback callback,
   object state
);

Parameters

buffer: The data to send.
offset: The zero-based position in the buffer parameter at which to begin sending data.
size: The number of bytes to send.
socketFlags: A bitwise combination of the SocketFlags values.
callback: The AsyncCallback delegate.
state: An object containing state information for this request.

Return Value

An IAsyncResult that references the asynchronous send.

Remarks

The BeginSend method starts asynchronously sending data through a socket. You must create a callback method that implements the AsyncCallback delegate. This callback method should use the EndSend method to complete sending data.

Exceptions

Exception Type	Condition
ArgumentNullException	buffer is a null reference (Nothing in Visual Basic).
SocketException	An operating system error occurs while accessing the VirtualSocket.
ArgumentOutOfRangeException	The specified offset or size exceeds the size of buffer.
ObjectDisposedException	The VirtualSocket has been closed.
