Question

如何获取调用ASP.NET页面的服务器的IP地址？我见过有关Response对象的内容，但在c＃中我是新手。非常感谢。

Answer 1

这应该有效：

 //this gets the ip address of the server pc

  public string GetIPAddress()
  {
     IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName()); // `Dns.Resolve()` method is deprecated.
     IPAddress ipAddress = ipHostInfo.AddressList[0];

     return ipAddress.ToString();
  }

OR

 //while this gets the ip address of the visitor making the call
  HttpContext.Current.Request.UserHostAddress;

Answer 2

Request.ServerVariables["LOCAL_ADDR"];

这为IP提供了对多宿主服务器的请求

Answer 3

上述情况很慢，因为它需要DNS调用（如果一个不可用，显然不会有效）。您可以使用下面的代码获取当前pc的本地IPV4地址及其相应子网掩码的映射：

public static Dictionary<IPAddress, IPAddress> GetAllNetworkInterfaceIpv4Addresses()
{
    var map = new Dictionary<IPAddress, IPAddress>();

    foreach (var ni in NetworkInterface.GetAllNetworkInterfaces())
    {
        foreach (var uipi in ni.GetIPProperties().UnicastAddresses)
        {
            if (uipi.Address.AddressFamily != AddressFamily.InterNetwork) continue;

            if (uipi.IPv4Mask == null) continue; //ignore 127.0.0.1
            map[uipi.Address] = uipi.IPv4Mask;
        }
    }
    return map;
}

警告：这尚未在Mono中实现

Answer 4

  //this gets the ip address of the server pc
  public string GetIPAddress()
  {
     string strHostName = System.Net.Dns.GetHostName();
     //IPHostEntry ipHostInfo = Dns.Resolve(Dns.GetHostName()); <-- Obsolete
     IPHostEntry ipHostInfo = Dns.GetHostEntry(strHostName);
     IPAddress ipAddress = ipHostInfo.AddressList[0];

     return ipAddress.ToString();
  }

Answer 5

这适用于IPv4：

public static string GetServerIP()
{            
    IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());

    foreach (IPAddress address in ipHostInfo.AddressList)
    {
        if (address.AddressFamily == AddressFamily.InterNetwork)
            return address.ToString();
    }

    return string.Empty;
}

以下快照摘自Mkyong，以显示Google chrome开发人员控制台内的网络标签。在“请求标头” 标签内，您可以看到所有服务器变量的列表，如下所示下方：

下面是几行代码，这些行获取了击中您应用程序的客户端的ipaddress

//gets the ipaddress of the machine hitting your production server              
string ipAddress = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; 

if (ipAddress == "" || ipAddress == null)  
{                                     
  //gets the ipaddress of your local server(localhost) during development phase                                                                         
  ipAddress = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];              
}

//Output:                                                                           
For production server - 122.169.106.247 (random)
For localhost         - ::1
