WCF學習問題：獲取客戶端IP地址

打算在WCF服務端記錄方法調用日志，因此需要記錄客戶端IP.

參考了：http://www.cnblogs.com/zeroone/archive/2012/05/05/2484473.html的方法

並且經過測試，獲取應該沒問題

        public string ClientIpAndPort() 
        { 
            OperationContext context = OperationContext.Current; 
            MessageProperties properties = context.IncomingMessageProperties; 
            RemoteEndpointMessageProperty endpoint = properties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
            return endpoint.Address + ":" + endpoint.Port.ToString(); 
        }
