public ref class Udp : public ComponentUse the Udp Component to send and receive UDP datagrams. It simplifies the use of UDP communications by providing methods to send/receive datagrams, listen for datagrams, and multicast/broadcast. Synchronous and asynchronous use is fully supported.
What follows are short usage descriptions. For more information, see the appropriate member topic.
Listen for datagrams: The Open method causes the Udp component to allocate a socket for sending and receiving datagrams.
Send/receive datagrams: Use the Send and Receive methods to send/receive datagrams.
Join/leave multicast groups: Use the JoinMulticastGroup to join a multicast group. Use the LeaveMulticastGroup to leave a multicast group.
Asynchronous use: Use the BeginSend and BeginReceive methods to send/receive datagrams asynchronously.
The following example demonstrates sending some datagrams to an echo server and receiving the datagrams from the echo server.
[Visual Basic]
Dim iterations as Integer = 3
' Listen on the default interface and an ephemeral port.
udp1.Open()
' Send several datagrams
Dim s as String = "test"
Dim i as Integer
For i=0 to iterations
Udp1.send(s, "MyEchoServer", 7)
Next
' receive the echoed datagrams, there should be 3...requiring 3 Udp.Receive calls.
For i=0 to iterations
Dim d as Datagram = Udp1.Receive(s.Length)
Debug.WriteLine(d.ToString())
Next
'* Output
'* ------------------------
'* test
'* test
'* test
'* ------------------------
'*
[C#]
int iterations = 3;
// Listen on the default interface and an ephemeral port.
udp1.Open();
// Send several datagrams
string s = "test";
for(int i=0; i<iterations; i++)
udp1.send(s, "MyEchoServer", 7);
// receive the echoed datagrams, there should be 3...requiring 3 Udp.Receive calls.
for(int i=0; i<iterations; i++)
{
Datagram d = udp1.Receive(s.Length);
Debug.WriteLine(d.ToString());
}
