Remarks
The SocketProtocolType enumeration defines the protocol type that the Socket class uses to establish a connection. This enumeration is used by the Socket constructor to specify the protocol for the new socket.
Example Usage
The following example demonstrates how to create a TCP client socket using the SocketProtocolType.Tcp value:
using System;
using System.Net;
using System.Net.Sockets;
public class SocketExample
{
public static void Main(string[] args)
{
try
{
// Create a TCP socket
Socket socket = new Socket(
AddressFamily.InterNetwork,
SocketType.Stream,
SocketProtocolType.Tcp
);
Console.WriteLine("TCP socket created successfully.");
// You can now proceed to connect, bind, send, and receive data.
// For demonstration purposes, we'll just close it.
socket.Close();
Console.WriteLine("Socket closed.");
}
catch (SocketException e)
{
Console.WriteLine($"SocketException: {e.Message}");
}
catch (Exception e)
{
Console.WriteLine($"An unexpected error occurred: {e.Message}");
}
}
}
