NET获取IP等信息

1. 在ASP.NET中专用属性：
获取服务器电脑名：Page.Server.ManchineName
获取用户信息：Page.User
获取客户端电脑名：Page.Request.UserHostName
获取客户端电脑IP：Page.Request.UserHostAddress
2. 在网络编程中的通用方法：
获取当前电脑名：static System.Net.Dns.GetHostName()
根据电脑名取出全部IP地址：static System.Net.Dns.Resolve(电脑名).AddressList
也可根据IP地址取出电脑名：static System.Net.Dns.Resolve(IP地址).HostName

3. 系统环境类的通用属性：
当前电脑名：static System.Environment.MachineName
当前电脑所属网域：static System.Environment.UserDomainName
当前电脑用户：static System.Environment.UserName

c#获取真实IP和代理IP

获取真实IP

public static string GetRealIP()
{
string ip;
try
{
HttpRequest request = HttpContext.Current.Request;

if (request.ServerVariables["HTTP_VIA"] != null)
{
ip = request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString().Split(',')[0].Trim();
}
else
{
ip = request.UserHostAddress;
}
}
catch (Exception e)
{
throw e;
}

return ip;
}

获取代理IP

public static string GetViaIP()
{
string viaIp = null;

try
{
HttpRequest request = HttpContext.Current.Request;

if (request.ServerVariables["HTTP_VIA"] != null)
{
viaIp = request.UserHostAddress;
}

}
catch (Exception e)
{

throw e;
}

return viaIp;

获取服务器的IP地址方法以DNS法较为简单实用，如下：
  using System.Net;

 

 private void ButtonIP_Click(object sender, System.EventArgs e)
  { 
     System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
     if ( addressList.Length>1)
     {   TextLIP.Text = addressList[0].ToString();
          TextSIP.Text = addressList[1].ToString();
     }
     else
     {
          TextLIP.Text = addressList[0].ToString();
          TextSIP.Text = "没有可用的连接";
     }
  }

获取服务器的IP地址与MAC地址另一方法如下：

   using System.Management;

 

   string stringMAC = "";
   string stringIP = "";
   ManagementClass MC = new ManagementClass "Win32_NetworkAdapterConfiguration");
   ManagementObjectCollection MOC= MC.GetInstances();
  
   foreach(ManagementObject MO in MOC)
   {
    if ((bool)MO["IPEnabled"] == true)
    {
     stringMAC += MO["MACAddress"].ToString();
     TextMAC.Text = stringMAC.ToString();
     string[] IPAddresses = (string[]) MO["IPAddress"];
     if(IPAddresses.Length > 0)
     stringIP = IPAddresses[0];
     TextIP.Text = stringIP.ToString();
    }
   }
