UdpClient.Receiveis a blocking call, and there is no events on theUdpClient. You use it to send packets to a server or multicast group and then callUdpClient.Receiveto wait for a response. You should read the class documentation[^] for theUdpClientin the .NET Framework SDK. It contains all the information you should need plus many examples of how to use it.Microsoft MVP, Visual C# My Articles
