C#编程获取IP地址的方法示例

/// <summary>/// 获取客户端Ip/// </summary>/// <returns></returns>public String GetClientIp(){  String clientIP = "";  if (System.Web.HttpContext.Current != null)  {    clientIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];    if (string.IsNullOrEmpty(clientIP) || (clientIP.ToLower() == "unknown"))    {      clientIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_REAL_IP"];      if (string.IsNullOrEmpty(clientIP))      {        clientIP = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];      }    }    else    {      clientIP = clientIP.Split(',')[0];    }  }  return clientIP;}

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