如何在MVC中获取客户端MAC地址

Question

我已经登录了页面，我想获取用户客户端的Mac地址，但是当我发布到服务器并获取服务器MACID时，我写了这段代码。如何获取用户客户端地址

string NetworkMacID = "";
IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
if (nics == null || nics.Length < 1)
  NetworkMacID = "";
else
  NetworkMacID = nics[0].GetPhysicalAddress().ToString();

return NetworkMacID;
