**1、获取客户端IP**

/// <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;
    }

**2、服务器端获取客户端请求IP和客户端机器名称**

/// <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);
    }
