WCF数据协定交互简单示例

工作原理：首先由客户端通过数据协定类NewsCL构造自定义类实例数据，并发送给WCF服务器端，服务器端WCF程序反序列化出NewsSV类实例数据，并修改实例数据的Title内容，限定在长度10内，并对实例数据的PublishDate加1天，然后返回给客户端，客户端收到数据后在屏幕上打印输出。
服务器端程序
IService.cs

using System;
using System.ServiceModel;


namespace ConsoleAppWcfNews
{
    [ServiceContract(Name ="news_sv",Namespace ="")]
    public interface IService
    {
        [OperationContract(Name = "postNews", Action = "post_act", ReplyAction = "post_rpy")]
         NewsSV postNews(NewsSV obj);


    }
}

MyService.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleAppWcfNews
{
    class MyService:IService
    {
        public NewsSV postNews(NewsSV obj)
        {
            string msg;

            obj.Title = obj.Title.Substring(0, 10);
            obj.PublishDate=obj.PublishDate.AddDays(1);

            msg = $"新闻标题：{obj.Title}\n新闻发布时间：{obj.PublishDate}\n";

            Console.WriteLine("新闻发布成功，概要如下：\n" + msg);
            return obj;
        }
    }
}

NewsSV.cs

using System;
using System.Collections.Generic;

        [DataMember]
        public DateTime PublishDate { get; set; }
        public ExtensionDataObject ExtensionData { get; set; }
    }
}

Program.cs

using System;
using System.Collections.Generic;

using System.Text;
using System.Threading.Tasks;

namespace ConsoleAppWcfNews

                host.Open();
                Console.WriteLine("服务已运行，请等待客户端调用。");
                Console.Read();
            }
        }
    }
}

客户端程序
