在MVC 4中獲取公共IP地址，客戶機的Lan IP地址和MAC地址？

Question

如何獲得公共IP地址，局域網IP地址&客戶機在MVC 4中的MAC地址？

我正在嘗試獲取客戶端計算機的IP地址。 Request.UserHostAddress給出Lan IP地址，但是

• 全球IP地址呢？
• 如何獲取公共IP地址？
• 谷歌，whatismyip.com和其他許多網站如何選擇我們的公有IP地址等。

Answer 1

對於LAN IP地址：

string ip = System.Web.HttpContext.Current.Request.UserHostAddress; 

對於公共IP地址：

public static string GetPublicIP() 
{ 
    string url = "http://checkip.dyndns.org"; 
    System.Net.WebRequest req = System.Net.WebRequest.Create(url); 
    System.Net.WebResponse resp = req.GetResponse(); 
    System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream()); 
    string response = sr.ReadToEnd().Trim(); 
    string[] a = response.Split(':'); 
    string a2 = a[1].Substring(1); 
    string[] a3 = a2.Split('<'); 
    string a4 = a3[0]; 
    return a4; 
} 

或

private string GetPublicIpAddress() 
    { 
     var request = (HttpWebRequest)WebRequest.Create("http://ifconfig.me"); 

     request.UserAgent = "curl"; // this simulate curl linux command 

     string publicIPAddress; 

     request.Method = "GET"; 
     using (WebResponse response = request.GetResponse()) 
     { 
      using (var reader = new StreamReader(response.GetResponseStream())) 
      { 
       publicIPAddress = reader.ReadToEnd(); 
      } 
     } 

     return publicIPAddress.Replace("\n", ""); 
    } 

對於MAC地址：

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; 
} 

試試這個，它可能對你有幫助。
