获取登录的IP或者信息

这是转载的，也不想去检查性能，对于这些成熟的代码，发在这里完全是懒，仅此而已！

1、获取客户端IP

1. /// <summary>
2. /// 获取客户端Ip
3. /// </summary>
4. /// <returns></returns>
5. public String GetClientIp()
6. {
7. String clientIP = "";
8. if (System.Web.HttpContext.Current != null)
9. {
10. clientIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
11. if (string.IsNullOrEmpty(clientIP) || (clientIP.ToLower() == "unknown"))
12. {
13. clientIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_REAL_IP"];
14. if (string.IsNullOrEmpty(clientIP))
15. {
16. clientIP = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
17. }
18. }
19. else
20. {
21. clientIP = clientIP.Split(',')[0];
22. }
23. }
24. return clientIP;
25. }

2、服务器端获取客户端请求IP和客户端机器名称

1. /// <summary>
2. /// 服务器端获取客户端请求IP和客户端机器名称
3. /// </summary>
4. public static void GetClientInfo()
5. {
6. OperationContext context = OperationContext.Current;
7. MessageProperties messageProperties = context.IncomingMessageProperties;
8. RemoteEndpointMessageProperty endpointProperty = messageProperties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
9. HttpRequestMessageProperty requestProperty = messageProperties[HttpRequestMessageProperty.Name] as HttpRequestMessageProperty;
10. string clientIp = !string.IsNullOrEmpty(requestProperty.Headers["X-Real-IP"]) ? requestProperty.Headers["X-Real-IP"] : endpointProperty.Address;
11. string clientName = Environment.MachineName;
12. Console.WriteLine("ClientIp: " + clientIp + "clientName:" + clientName);
13. }
