[問題] SocketType.Rdm之謎

[remmurds (雷穆爾德‧小一)]

為了要找到建立這種Socket類型的方法

我寫了下面這一段程式:


    List<Socket> socketlist = new List<Socket>();

    Array families = Enum.GetValues(typeof(AddressFamily));
    Array protocols = Enum.GetValues(typeof(ProtocolType));

    foreach (AddressFamily family in families)
    {
        foreach (ProtocolType protocol in protocols)
        {
            try
            {
                socketlist.Add(new Socket(family, SocketType.Rdm, protocol));
            }
            catch (SocketException)
            {

            }
            Thread.Sleep(1);
        }
    }

    Console.WriteLine("成功建立的Rdm Socket: ");

    foreach (Socket socket in socketlist)
    {
        Console.WriteLine("AddressFamily: " + socket.AddressFamily.ToString());
        Console.WriteLine("Protocol: " + socket.ProtocolType.ToString());
    }



結果居然沒有任何一種AddressFamily和ProtocolType的組合

可以成功建立Rdm類型的Socket

這究竟要怎麼建立呢?
