Windows 7中的MAC地址 [英] MAC address in Windows 7

问题描述

您好，先生

请帮助我解决这两个问题

1.下面的代码显示了XP中的mac地址，但在Windows7中为空字符串.
2.是否有可能直接通过查询查找mac地址，而不是循环" foreach "语句.

Hello sir

Please help me in these two issues

1. Below code shows mac address in XP but empty string in Windows7.
2. Is there any chance to find mac address directly with a query instead of looping "foreach" statement.

string MACAddress = String.Empty;
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
                ManagementObjectCollection moc = mc.GetInstances();                
                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;

推荐答案

检查一下

Check this out

/// <summary>
/// returns the mac address of the first operation nic found.
/// </summary>
/// <returns></returns>
private string GetMacAddress()
{
    string macAddresses = "";

    foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
    {
        if (nic.OperationalStatus == OperationalStatus.Up)
        {
            macAddresses += nic.GetPhysicalAddress().ToString();
            break;
        }
    }
    return macAddresses;
}

尊敬的先生，谢谢您的答复.

当电缆插入时，我得到了mac地址，但是当我拔出电缆时，得到了相同的错误(空字符串).我的大多数客户都没有网络连接.

有没有其他方法可以在Win 7中获得Mac地址?
