WCF 取得用戶端IP

簡單定義一個服務：
         

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace ClientInfoSample
{
    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        string GetData(string value);
    }
}

在建立通道之後按照可以取得：using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Channels; 

namespace ClientInfoSample
{
    public class MyService : IService
    {
        public string GetData(string value)
        {
            OperationContext context = OperationContext.Current;
            MessageProperties essageProperties = context.IncomingMessageProperties;
            RemoteEndpointMessageProperty endpointProperty =
            messageProperties  [RemoteEndpointMessageProperty.Name]
                as RemoteEndpointMessageProperty;

            return string.Format("Hello {0}! Your IP address is {1} and your port is {2}",  value, endpointProperty.Address, endpointProperty.Port);
        }
    }
}
