示例

下面的代码示例显示本地计算机上所有接口的物理地址。

void ShowNetworkInterfaces()
{
   IPGlobalProperties^ computerProperties = IPGlobalProperties::GetIPGlobalProperties();
   array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces();
   Console::WriteLine( L"Interface information for {0}.{1}     ", computerProperties->HostName, computerProperties->DomainName );
   if ( nics == nullptr || nics->Length < 1 )
   {
      Console::WriteLine( L"  No network interfaces found." );
      return;
   }

   Console::WriteLine( L"  Number of interfaces .................... : {0}", (nics->Length).ToString() );
   IEnumerator^ myEnum1 = nics->GetEnumerator();
   while ( myEnum1->MoveNext() )
   {
      NetworkInterface^ adapter = safe_cast<NetworkInterface^>(myEnum1->Current);
      IPInterfaceProperties^ properties = adapter->GetIPProperties();
      Console::WriteLine();
      Console::WriteLine( adapter->Description );
      Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );
      Console::WriteLine( L"  Interface type .......................... : {0}", adapter->NetworkInterfaceType );
      Console::Write( L"  Physical address ........................ : " );
      PhysicalAddress^ address = adapter->GetPhysicalAddress();
      array<Byte>^bytes = address->GetAddressBytes();
      for ( int i = 0; i < bytes->Length; i++ )
      {
         
         // Display the physical address in hexadecimal.
         Console::Write( L"{0}", bytes[ i ].ToString( L"X2" ) );
         
         // Insert a hyphen after each byte, unless we are at the end of the 
         // address.
         if ( i != bytes->Length - 1 )
         {
            Console::Write( L"-" );
         }

      }
      Console::WriteLine();
   }
}

public static void ShowNetworkInterfaces()
{
    IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    Console.WriteLine("Interface information for {0}.{1}     ",
            computerProperties.HostName, computerProperties.DomainName);
    if (nics == null || nics.Length < 1)
    {
        Console.WriteLine("  No network interfaces found.");
        return;
    }

    Console.WriteLine("  Number of interfaces .................... : {0}", nics.Length);
    foreach (NetworkInterface adapter in nics)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties(); //  .GetIPInterfaceProperties();
        Console.WriteLine();
        Console.WriteLine(adapter.Description);
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, '='));
        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType);
        Console.Write("  Physical address ........................ : ");
        PhysicalAddress address = adapter.GetPhysicalAddress();
        byte[] bytes = address.GetAddressBytes();
        for (int i = 0; i < bytes.Length; i++)
        {
            // Display the physical address in hexadecimal.
            Console.Write("{0}", bytes[i].ToString("X2"));
            // Insert a hyphen after each byte, unless we're at the end of the address.
            if (i != bytes.Length - 1)
            {
                Console.Write("-");
            }
        }
        Console.WriteLine();
    }
}

注解

MAC 地址或物理地址是一个硬件地址，用于唯一标识网络上的每个节点，例如计算机或打印机。

此类的实例由 NetworkInterface.GetPhysicalAddress 方法返回。

构造函数

PhysicalAddress(Byte[])

初始化 PhysicalAddress 类的新实例。

字段

None	返回一个具有零长度地址的新 PhysicalAddress 实例。 此字段为只读。

方法

Equals(Object)	比较两个 PhysicalAddress 实例。
GetAddressBytes()	返回当前实例的地址。
GetHashCode()	返回物理地址的哈希值。
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
Parse(ReadOnlySpan<Char>)	分析指定的范围，并将其内容存储为由此方法返回的 PhysicalAddress 的地址字节。
Parse(String)	分析指定的 String 并将其内容存储为由此方法返回的 PhysicalAddress 的地址字节。
ToString()	返回此实例的地址的 String 表示形式。
TryParse(ReadOnlySpan<Char>, PhysicalAddress)	尝试将硬件地址的跨度表示形式转换为 PhysicalAddress 实例。 一个指示转换是否成功的返回值。
TryParse(String, PhysicalAddress)	尝试将硬件地址的字符串表示形式转换为 PhysicalAddress 实例。 一个指示转换是否成功的返回值。
