为什么我们需要使用c＃.net获取MAC地址的网络连接？

问题描述

您好，



为什么我们需要使用c＃.net获取MAC地址的LAN网络连接？



当我禁用LAN网络时，没有获得MAC地址，为什么？



我想获得没有LAN网络的MAC地址，是否可能？



我也使用过两个代码： -

首先： -

public static String GetMACAddress（）

{

#region获取MAC地址

尝试

{

ManagementClass mc = new ManagementClass（ Win32_NetworkAdapterConfiguration）;

ManagementObjectCollection moc = mc.GetInstances（）;

string MACAddress = String.Empty;

foreach（ManagementObject mo in moc）

{

if（MACAddress == String.Empty）//仅从第一张卡返回MAC地址

{

if（（bool）mo [IPEnabled] == true）MACAddress = mo [MacAddress]。ToString（）;

}

mo.Dispose（）;

}



MACAddress = MACAddress.Replace（：，）;

返回MACAddress;

}

catch（例外情况）

{

抛出新例外（ex .Message）;

}

#endregion

}



第二名： -

  public   string  GetMACAddress（）
 {
 NetworkInterface [] nics = NetworkInterface.GetAllNetworkInterfaces（）; 
 字符串 sMacAddress = 字符串 .Empty; 
  foreach （NetworkInterface adapter  in  nics）
 {
  if （sMacAddress ==  String  .Empty） //  仅从第一张卡返回MAC地址 
 {
 IPInterfaceProperties properties = adapter.GetIPProperties（）; 
 sMacAddress = adapter.GetPhysicalAddress（）。ToString（）; 
} 
}  return  sMacAddress; 
} 

但我的目的不是解决。



请帮帮我。



先谢谢。

Hello,

Why we need LAN network connectivity for Get MAC Address using c# .net?

When i disabled LAN network so, did not get MAC Address, Why?

I want to Get MAC Address without LAN Network, is it Possible?

I have used both code also:-
First:-
public static String GetMACAddress()
{
#region Get MAC Address
try
{
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
string MACAddress = String.Empty;
foreach (ManagementObject mo in moc)
{
if (MACAddress == String.Empty) // only return MAC Address from first card
{
if ((bool)mo["IPEnabled"] == true) MACAddress = mo["MacAddress"].ToString();
}
mo.Dispose();
}

MACAddress = MACAddress.Replace(":", "");
return MACAddress;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
#endregion
}

Second:-

public string GetMACAddress()
        {
            NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
            String sMacAddress = string.Empty;
            foreach (NetworkInterface adapter in nics)
            {
                if (sMacAddress == String.Empty)// only return MAC Address from first card
                {
                    IPInterfaceProperties properties = adapter.GetIPProperties();
                    sMacAddress = adapter.GetPhysicalAddress().ToString();
                }
            } return sMacAddress;
        }

But my purpose is not solving.

Please help me.

Thanks in Advance.
