ProtocolType Enum

Summary

The ProtocolType enumeration defines a set of network protocols. You use these values with the Socket constructor to specify the protocol that the Socket will use.

Syntax

Members

• Udp
  User Datagram Protocol (UDP).
• Tcp
  Transmission Control Protocol (TCP).
• Icmp
  Internet Control Message Protocol (ICMP).
• IP
  Internet Protocol (IP).
• Unknown
  An unknown protocol.
• Unspecified
  An unspecified protocol.
• Ipx
  Internet Packet Exchange (IPX) protocol.
• Spx
  Sequenced Packet Exchange (SPX) protocol.
• SpxII
  SPX II protocol.
• IPv6
  Internet Protocol version 6 (IPv6).
• ND
  Netdisk Protocol.
• Rdp
  Remote Desktop Protocol.
• Icmpv6
  Internet Control Message Protocol version 6 (ICMPv6).

Example

The following example demonstrates how to create a Socket that uses UDP.

using System;
using System.Net;
using System.Net.Sockets;

public class SocketExample
{
    public static void Main(string[] args)
    {
        // Create a Socket that uses UDP and IPv4.
        Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);

        Console.WriteLine("UDP Socket created successfully.");

        // You would typically bind or connect the socket here.
        // For demonstration, we'll just close it.
        socket.Close();
    }
}

Remarks

When creating a Socket, you must specify the address family, socket type, and protocol type. For example, to create a TCP socket for IPv4, you would use:

Socket tcpSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

This enumeration provides a convenient way to select the desired protocol without having to know its underlying integer value.
