本文介绍如何在.NET环境下自定义IPX/SPX地址类以实现网络编程。通过继承EndPoint类并实现必要的构造函数及方法，如创建、序列化等，可以为IPX/SPX通信打下坚实的基础。

要实现 IPX/SPX 必须自己写IPX地址类

它派生于 EndPoint. 因为.NET没有提供此类所以必须自己写

public class IPXEndPoint : EndPoint { byte[] NetNum; byte[] NodeNum; ushort Prot; public IPXEndPoint(ushort prot) { NetNum = new byte[4]; NodeNum = new byte[6]; Prot = prot; } public IPXEndPoint(string node, int num, ushort prot) { byte[] nodex = new byte[6]; string[] nodesp = node.Split(new char[] { '-' }, StringSplitOptions.RemoveEmptyEntries); if (nodesp.Length == 6) { for(int i=0;i<6;i++) { nodex[i] = Convert.ToByte("0x"+nodesp[i],16); } this.NodeNum = nodex; this.NetNum = new byte[4]; NetNum[3] = (byte)(num >> 24); NetNum[2] = (byte)(num >> 16); NetNum[1] = (byte)(num >> 8); NetNum[0] = (byte)(num); this.Prot = prot; } else { throw new ArgumentException("node"); } } public IPXEndPoint(byte[] netnum, byte[] nodenum, ushort prot) { this.NetNum = netnum; this.NodeNum = nodenum; this.Prot = prot; } public override System.Net.Sockets.AddressFamily AddressFamily { get { return System.Net.Sockets.AddressFamily.Ipx; } } public override EndPoint Create(SocketAddress socketAddress) { if (socketAddress == null) { throw new ArgumentNullException("socketAddress"); } if (socketAddress.Family != this.AddressFamily) { throw new ArgumentException("socketAddress"); } if (socketAddress.Size < 14) { throw new ArgumentException("socketAddress"); } ushort port = (ushort)(((socketAddress[12] << 8) & 0xff00) | socketAddress[13]); //return new IPEndPoint(((((socketAddress[4] & 0xff) | ((socketAddress[5] << 8) & 0xff00)) | ((socketAddress[6] << 0x10) & 0xff0000)) | (socketAddress[7] << 0x18)) & ((long)0xffffffffL), port); byte[] netnum = new byte[4]; netnum[3] = socketAddress[2]; netnum[2] = socketAddress[3]; netnum[1] = socketAddress[4]; netnum[0] = socketAddress[5]; byte[] codenum = new byte[6]; codenum[0] = socketAddress[6]; codenum[1] = socketAddress[7]; codenum[2] = socketAddress[8]; codenum[3] = socketAddress[9]; codenum[4] = socketAddress[10]; codenum[5] = socketAddress[11]; return new IPXEndPoint(netnum, codenum, port); } public override SocketAddress Serialize() { SocketAddress address = new SocketAddress(System.Net.Sockets.AddressFamily.Ipx, 14); address[2]=NetNum[3]; address[3] = NetNum[2]; address[4] = NetNum[1]; address[5] = NetNum[0]; address[6] = NodeNum[0]; address[7] = NodeNum[1]; address[8] = NodeNum[2]; address[9] = NodeNum[3]; address[10] = NodeNum[4]; address[11] = NodeNum[5]; address[12] = (byte)(Prot >> 8); address[13] = (byte)Prot; return address; } public override string ToString() { int num = BitConverter.ToInt32(NetNum,0); string node = ""; for(int i=0;i<NodeNum.Length;i++) { node += Convert.ToString(NodeNum[i], 16); if (i < NodeNum.Length - 1) { node += "-"; } } return node + ":0x" + Convert.ToString(num,16) + ":" + Prot; } }

写好后初始化SOCKET对象:

sock = new Socket(AddressFamily.Ipx, SocketType.Stream, ProtocolType.Spx);

注意 Addressfamily和protype

初始化地址

IPXEndPoint myEnd = new IPXEndPoint("MAC地址", 节点号, 端口);

sock.Bind(myEnd);

其他的和常规的TCP服务一样..
