如何在C＃中获取客户端REAL IP地址？ [英] How can I get the client REAL IP address in C# ?

问题描述

请帮助我！



如何在ASP.NET页面中获取客户端的真实IP地址？



我尝试了很多方法来尝试获得这个值，但是失败了。

这是我尝试过的方法：

 Request.UserHostAddress 
 Request.ServerVariables [  HTTP_X_FORWARDED_FOR] 
 Request.ServerVariables [  REMOTE_ADDR] 

结果是：

 UserHostAddress： 16 . 85 。 175 。 133  
 HTTP_X_FORWARDED_FOR：
 REMOTE_ADDR： 16 。 85 。 175 。 133  

这个它不是客户端IP地址的代理地址。



获得此价值的任何解决方案？



谢谢！

解决方案

你在外面看到的IP地址是什么意思。

要获得此IP地址，您必须使用手动或以编程方式（通过API）提供此信息的服务。



例如，要使用''http://whatismyip.com''，以下代码将以编程方式获取IP：

 UTF8Encoding utf8 = < span class =code-keyword> new  UTF8Encoding（）; 
 WebClient mywebClient =  new  WebClient（）; 
  String  externalIp = utf8.GetString（mywebClient.DownloadData（  http://whatismyip.com/automation/n09230945.asp））; 
 
 Response.Write（ 您的外部IP地址为： + externalIp ）; 

Please help me!

How can I get the client''s real IP address in ASP.NET page?

I have tried many ways to try to get this value, but failed.
Here is my tried methods:

Request.UserHostAddress
Request.ServerVariables["HTTP_X_FORWARDED_FOR"]
Request.ServerVariables["REMOTE_ADDR"]

The result is:

UserHostAddress: 16.85.175.133
HTTP_X_FORWARDED_FOR:
REMOTE_ADDR: 16.85.175.133

This is not client IP address, it''s Proxy address.

Any solutions to get this value ?

Thank you!

解决方案

What you mean in the IP address that is seen from outside.
To get this IP address, you must use a service that provide this information manually or programatically (via API).

For example, to use ''http://whatismyip.com'' the following code will obtain the IP programatically:

UTF8Encoding utf8 = new UTF8Encoding();
WebClient mywebClient = new WebClient();
String externalIp = utf8.GetString(mywebClient.DownloadData("http://whatismyip.com/automation/n09230945.asp"));

Response.Write("Your External IP Address is: " + externalIp );
