DataIn Event

Fired when data is received.

Syntax

• C#
• VB.NET

public event OnDataInHandler OnDataIn;

public delegate void OnDataInHandler(object sender, UdpportDataInEventArgs e);

public class UdpportDataInEventArgs : EventArgs {
  public string Datagram { get; }
  public byte[] DatagramB { get; }
  public string SourceAddress { get; }
  public int SourcePort { get; }
}

Public Event OnDataIn As OnDataInHandler

Public Delegate Sub OnDataInHandler(sender As Object, e As UdpportDataInEventArgs)

Public Class UdpportDataInEventArgs Inherits EventArgs
  Public ReadOnly Property Datagram As String
  Public ReadOnly Property DatagramB As Byte()
  Public ReadOnly Property SourceAddress As String
  Public ReadOnly Property SourcePort As Integer
End Class

Remarks

The DataIn event is fired every time a new datagram is received.

Datagram contains the packet as sent by the remote host.

SourceAddress contains the IP number (Internet address) of the remote host, and SourcePort contains the port from which the packet originated.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.
