VirtualSocket.BeginSendTo Method

Sends data asynchronously to a specific remote host.

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

[C#]
public virtual IAsyncResult BeginSendTo(
   byte[] buffer,
   int offset,
   int size,
   SocketFlags socketFlags,
   EndPoint remoteEP,
   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.
remoteEP: An EndPoint that represents the remote device.
callback: The AsyncCallback delegate.
state: An object containing state information for this request.

Return Value

An IAsyncResult that references the asynchronous send.

Remarks

The BeginSendTo 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 EndSendTo method to complete sending data.

Exceptions

Exception Type	Condition
ArgumentException	buffer is a null reference (Nothing in Visual Basic). -or- remoteEP 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.
