C# 获取网络适配器

shiy720

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

1. using System.Net.NetworkInformation;
   
2. 
   
3. NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
   
4. 
   
5. foreach (NetworkInterface adapter in adapters)
   
6. {
   
7.     Console.WriteLine(adapter.Name);
   
8.     Console.WriteLine(adapter.Description);
   
9.     Console.WriteLine(adapter.Speed); // 速度
   
10.     Console.WriteLine(adapter.GetPhysicalAddress()); // MAC 地址
    
11.     Console.WriteLine(adapter.GetIPProperties()); // IP 配置
    
12. }

使用 System.Management 命名空间

1. using System.Management;
   
2. 
   
3. ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapter");
   
4. 
   
5. foreach (ManagementObject adapter in searcher.Get())
   
6. {
   
7.     Console.WriteLine(adapter["Name"]);
   
8.     Console.WriteLine(adapter["Description"]);
   
9.     Console.WriteLine(adapter["Speed"]); // 速度
   
10.     Console.WriteLine(adapter["MACAddress"]); // MAC 地址
    
11. }

使用 System.Net.Sockets 命名空间

1. using System.Net.Sockets;
   
2. 
   
3. IPHostEntry hostEntry = Dns.GetHostEntry(Dns.GetHostName());
   
4. 
   
5. foreach (IPAddress address in hostEntry.AddressList)
   
6. {
   
7.     Console.WriteLine(address.AddressFamily);
   
8.     Console.WriteLine(address.ToString());
   
9. }

复制代码

使用 WMI (Windows Management Instrumentation)

1. using System.Management;
   
2. 
   
3. ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");
   
4. 
   
5. foreach (ManagementObject adapter in searcher.Get())
   
6. {
   
7.     Console.WriteLine(adapter["Caption"]);
   
8.     Console.WriteLine(adapter["Description"]);
   
9.     Console.WriteLine(adapter[" IPAddress"]); // IP 地址
   
10.     Console.WriteLine(adapter["DefaultIPGateway"]); // 默认网关
    
11.     Console.WriteLine(adapter["DNSDomain"]); // DNS 域
    
12. }

使用 System.Linq 和 System.Net.NetworkInformation 命名空间

1. 
   
2. using System.Linq;
   
3. using System.Net.NetworkInformation;
   
4. 
   
5. NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
   
6. 
   
7. var networkAdapters = adapters.Select(adapter => new
   
8. {
   
9.     Name = adapter.Name,
   
10.     Description = adapter.Description,
    
11.     Speed = adapter.Speed,
    
12.     MacAddress = adapter.GetPhysicalAddress(),
    
13.     IpAddress = adapter.GetIPProperties().UnicastAddresses.FirstOrDefault().Address
    
14. });
    
15. 
    
16. foreach (var adapter in networkAdapters)
    
17. {
    
18.     Console.WriteLine(adapter.Name);
    
19.     Console.WriteLine(adapter.Description);
    
20.     Console.WriteLine(adapter.Speed);
    
21.     Console.WriteLine(adapter.MacAddress);
    
22.     Console.WriteLine(adapter.IpAddress);
    
23. }

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。
