Retrive MAC與IP地址地址使用LINQ

Question

我要檢索的MAC與IP地址地址...

var nics = NetworkInterface.GetAllNetworkInterfaces() 
    .Where(ipProp => ipProp.GetIPProperties().UnicastAddresses 
        .Where(ip => ip.Address.ToString().Equals("192.168.1.111")) 
    ); 

我得到一個錯誤：

"Cannot implicitly convert type 'System.Collections.Generic.IEnumerable' to 'bool'"

我該如何解決這個問題？

Answer 1

NetworkInterface networkInterface = NetworkInterface.GetAllNetworkInterfaces().Where(ipProp => ipProp.GetIPProperties().UnicastAddresses.FirstOrDefault(ip => ip.Address.ToString().Equals("YOUR_IP")) != null).FirstOrDefault(); 
if (networkInterface != null) 
{ 
    Console.WriteLine(networkInterface.GetPhysicalAddress()); 
}
