帮我优化一下这段代码 static void Main(string[] args) { IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName()); IPAddress localIP = IPAddress.None; foreach (IPAddress ip in host.AddressList) { if (ip.AddressFamily == AddressFamily.InterNetwork) { localIP = ip; break; } } //实例化Socket m_ServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); //向操作系统申请一个可用的IP和端口来通讯 m_ServerSocket.Bind(new IPEndPoint(localIP, m_Port)); //最多1000个排队连接请求 m_ServerSocket.Listen(1000); Console.WriteLine("启动监听{0}", m_ServerSocket.LocalEndPoint.ToString()); Thread mThread = new Thread(ListenClientCallBack); mThread.Start(); Console.ReadLine(); }

### 获取本机IP地址的代码示例 以下提供了多种编程语言中用于获取本机IP地址的代码示例，涵盖了Java、C#和Python等常用语言。 #### Java 中获取本机IP地址 在Java中，可以通过`InetAddress`类来获取本机IP地址。然而，由于计算机可能具有多个网络接口（如以太网、Wi-Fi、蓝牙等），简单地调用`InetAddress.getLocalHost().getHostAddress()`可能无法准确返回所需的IP地址[^1]。因此，需要遍历所有网络接口并筛选出有效的IPv4地址。 ```java import java.net.InetAddress; import java.net.NetworkInterface; import java.net.SocketException; import java.util.Enumeration; public class GetLocalIPAddress { public static void main(String[] args) throws SocketException { try { Enumeration<NetworkInterface> networkInterfaces = NetworkInterface.getNetworkInterfaces(); while (networkInterfaces.hasMoreElements()) { NetworkInterface networkInterface = networkInterfaces.nextElement(); Enumeration<InetAddress> inetAddresses = networkInterface.getInetAddresses(); while (inetAddresses.hasMoreElements()) { InetAddress inetAddress = inetAddresses.nextElement(); if (!inetAddress.isLoopbackAddress() && inetAddress.getHostAddress().contains(".")) { System.out.println("IP Address: " + inetAddress.getHostAddress()); } } } } catch (SocketException e) { e.printStackTrace(); } } } ``` #### C# 中获取本机IP地址 在C#中，可以使用`Dns`类和`IPAddress`类来获取本机的所有IP地址，并通过筛选条件获取IPv4地址[^2]。 ```csharp using System; using System.Net; using System.Net.Sockets; class Program { static void Main() { string hostName = Dns.GetHostName(); IPHostEntry ipEntry = Dns.GetHostEntry(hostName); IPAddress[] addressList = ipEntry.AddressList; foreach (IPAddress ipAddress in addressList) { if (ipAddress.AddressFamily == AddressFamily.InterNetwork) { Console.WriteLine("IP Address: " + ipAddress.ToString()); } } } } ``` #### Python 中获取本机IP地址 在Python中，可以使用`socket`模块来获取本机IP地址。需要注意的是，`socket.gethostbyname(socket.gethostname())`可能无法在所有情况下正确返回IP地址，因此推荐使用`socket`结合`netifaces`库来遍历网络接口并筛选IPv4地址[^3]。 ```python import socket import netifaces as ni def get_ipv4_addresses(): interfaces = ni.interfaces() ipv4_addresses = [] for interface in interfaces: try: addresses = ni.ifaddresses(interface) if ni.AF_INET in addresses: ipv4_info = addresses[ni.AF_INET] for info in ipv4_info: ipv4_addresses.append(info['addr']) except Exception as e: continue return ipv4_addresses if __name__ == "__main__": ipv4_addresses = get_ipv4_addresses() for ip in ipv4_addresses: print(f"IP Address: {ip}") ``` #### IPv4与IPv6地址的区别 在获取IP地址时，通常更关注IPv4地址，因为它是目前最常用的协议。IPv4地址由四个以点分隔的十进制数构成，例如`192.168.1.100`。相比之下，IPv6地址更为复杂，由八个以冒号分隔的十六进制数组成[^4]。在上述代码示例中，均已包含筛选IPv4地址的逻辑。
