C# 获取网络适配器

本帖最后由 shiy720 于 2024-6-8 10:23 编辑

C# 中有多种方式可以获取网络适配器，以下是一些常见的方法：

使用 System.Net.NetworkInformation 命名空间
using System.Net.NetworkInformation;

NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();

foreach (NetworkInterface adapter in adapters)
{
    Console.WriteLine(adapter.Name);
    Console.WriteLine(adapter.Description);
    Console.WriteLine(adapter.Speed); // 速度
    Console.WriteLine(adapter.GetPhysicalAddress()); // MAC 地址
    Console.WriteLine(adapter.GetIPProperties()); // IP 配置
}
使用 System.Management 命名空间
using System.Management;

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapter");

foreach (ManagementObject adapter in searcher.Get())
{
    Console.WriteLine(adapter["Name"]);
    Console.WriteLine(adapter["Description"]);
    Console.WriteLine(adapter["Speed"]); // 速度
    Console.WriteLine(adapter["MACAddress"]); // MAC 地址
}
使用 System.Net.Sockets 命名空间
using System.Net.Sockets;

IPHostEntry hostEntry = Dns.GetHostEntry(Dns.GetHostName());

foreach (IPAddress address in hostEntry.AddressList)
{
    Console.WriteLine(address.AddressFamily);
    Console.WriteLine(address.ToString());
}
使用 WMI (Windows Management Instrumentation)
using System.Management;

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");

foreach (ManagementObject adapter in searcher.Get())
{
    Console.WriteLine(adapter["Caption"]);
    Console.WriteLine(adapter["Description"]);
    Console.WriteLine(adapter[" IPAddress"]); // IP 地址
    Console.WriteLine(adapter["DefaultIPGateway"]); // 默认网关
    Console.WriteLine(adapter["DNSDomain"]); // DNS 域
}
使用 System.Linq 和 System.Net.NetworkInformation 命名空间

using System.Linq;
using System.Net.NetworkInformation;

NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();

var networkAdapters = adapters.Select(adapter => new
{
    Name = adapter.Name,
    Description = adapter.Description,
    Speed = adapter.Speed,
    MacAddress = adapter.GetPhysicalAddress(),
    IpAddress = adapter.GetIPProperties().UnicastAddresses.FirstOrDefault().Address
});

foreach (var adapter in networkAdapters)
{
    Console.WriteLine(adapter.Name);
    Console.WriteLine(adapter.Description);
    Console.WriteLine(adapter.Speed);
    Console.WriteLine(adapter.MacAddress);
    Console.WriteLine(adapter.IpAddress);
}
这些方法可以获取到网络适配器的基本信息，如名称、描述、速度、MAC 地址、IP 地址等。
