Answer 1

ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");  
  ManagementObjectCollection nics = mc.GetInstances();  
  foreach (ManagementObject nic in nics)  
  {  
  if (Convert.ToBoolean(nic["ipEnabled"]) == true)  
  {  
  Console.WriteLine((nic["IPAddress"] as String[])[0]);  
    
  }    }

Answer 2

string GetIp()   
  {
  string userIP = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];   
  if (userIP == null || userIP == "")   
  {   
  userIP = Request.ServerVariables["REMOTE_ADDR"];     }   
  return userIP;   
}   

Answer 3

public static string GetIPAddress()
    {        string user_IP = string.Empty;
        if (System.Web.HttpContext.Current.Request.ServerVariables["HTTP_VIA"] != null)
        {
            if (System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
            {
                user_IP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
            }
            else
            {
                user_IP = System.Web.HttpContext.Current.Request.UserHostAddress;
            }
        }
        else
        {
            user_IP = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString();
        }
        return user_IP;
    }
 

Answer 4

是相同，但是要下载的同时触发获取ip，只访问页面不下载，是不记录ip的

他点击下载时你用AJAX执行访问一个后台程序，后台程序中执行这个获取起IP的方法
