WCF客户端代理

• 创建类库WCFServiceProxy
• 添加System.ServiceModel、WCFService（见上篇文章）引用
• 创建类：BookServiceClient

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.Text;
using System.Threading.Tasks;
using WCFService;
using WCFService.Models;
 
namespace WCFServiceProxy
{
    public class BookServiceClient : ClientBase<IBookService>, IBookService
    {
        public BookServiceClient() : base() { }
        public BookServiceClient(string endpointConfigurationName) : base(endpointConfigurationName) { }
        public BookServiceClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { }
        public BookServiceClient(string endpointConfigurationName, EndpointAddress remoteAddress) : base(endpointConfigurationName, remoteAddress) { }
        public BookServiceClient(Binding binding, EndpointAddress remoteAddress) : base(binding, remoteAddress) { }
        public bool Add(string name, double price)
        {
            return base.Channel.Add(name, price);
        }
 
        public List<Book> GetList()
        {
            return base.Channel.GetList();
        }
    }
}

创建类BookServiceProxy

                client.Close();
