c# - 如何从本地电脑获取蓝牙mac地址？

Question

我想在运行我的应用程序的电脑上获取蓝牙设备的 mac 地址。

我尝试了以下方法：

private void GetMacAddress()
{
     string macAddresses = "";
     foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
     {
          if (nic.OperationalStatus == OperationalStatus.Up)
          {
               macAddresses += nic.GetPhysicalAddress().ToString();
               Console.WriteLine(macAddresses);
          }
     }
}

但输出与命令提示符中的“ipconfig /all”不匹配。它不打印我的蓝牙 mac 地址。有什么解决办法吗？

我已准备好解析从“ipconfig /all”获得的输出，但如何将输出作为字符串获取？

Answer 1

public static PhysicalAddress GetBTMacAddress()  {

    foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces()) {

        // Only consider Bluetooth network interfaces
        if (nic.NetworkInterfaceType != NetworkInterfaceType.FastEthernetFx && 
            nic.NetworkInterfaceType != NetworkInterfaceType.Wireless80211){

            return nic.GetPhysicalAddress();
        }
    }
    return null;
}

您也许可以使用 WMI 来获得结果。特此链接到通过网络设备跟踪的 WMI 解决方案。

我在这里发布代码以防网站关闭，但所有功劳归于原作者 PsychoCoder。 在 C# 中使用 WMI 获取 MAC 地址

和代码：

//Namespace reference
using System.Management;

/// <summary>
/// Returns MAC Address from first Network Card in Computer
/// </summary>
/// <returns>MAC Address in string format</returns>
public string FindMACAddress()
{
    //create out management class object using the
    //Win32_NetworkAdapterConfiguration class to get the attributes
    //af the network adapter
    ManagementClass mgmt = new ManagementClass("Win32_NetworkAdapterConfiguration");
    //create our ManagementObjectCollection to get the attributes with
    ManagementObjectCollection objCol = mgmt.GetInstances();
    string address = String.Empty;
    //My modification to the code
    var description = String.Empty;
    //loop through all the objects we find
    foreach (ManagementObject obj in objCol)
    {
        if (address == String.Empty)  // only return MAC Address from first card
        {
            //grab the value from the first network adapter we find
            //you can change the string to an array and get all
            //network adapters found as well
            if ((bool)obj["IPEnabled"] == true)
            {
                address = obj["MacAddress"].ToString();
                description = obj["Description"].ToString();
            }
        }
       //dispose of our object
       obj.Dispose();
    }
    //replace the ":" with an empty space, this could also
    //be removed if you wish
    address = address.Replace(":", "");
    //return the mac address
    return address;
}

请务必包含对 System.Management 的引用。为了让您获得网络设备名称，您可以使用obj["Description"].ToString();

您还可以查看有关 WMI 的 MSDN，特别是Win32_NetworkAdapterConfiguration 类

希望这可以帮助。
