WCF 合同(Contract) 學習

 數據合同定義

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

namespace Contracts
{
    [DataContract]
    public class Person
    {
        [DataMember]
        public string Name { get; set; }

        [DataMember]
        public int Mark { get; set; }
    }
}

服務合同定義

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

namespace Contracts
{
    [ServiceContract(SessionMode=SessionMode.Required)]
    public interface IAwardService
    {
        [OperationContract(IsOneWay = true,IsInitiating=true)]
        void SetPassMark(int passMark);

        [OperationContract]
        Person[] GetAwardedPeople(Person[] peopleToTest);
    }
}

新建WCF服務程序

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

namespace wcfservice
{
    // 注意: 使用「重構」菜單上的「重命名」命令，能夠同時更改代碼、svc 和配置文件中的類名「AwardService」。
    public class AwardService : IAwardService
    {
        private int passMark;

        public void SetPassMark(int passMark)
        {
            this.passMark = passMark;
        }

        public Person[] GetAwardedPeople(Person[] peopleToTest)
        {
            List<Person> result = new List<Person>();
            foreach (Person person in peopleToTest)
            {
                result.Add(person);
            }
            return result.ToArray();
        }
    }
}

修改Web.config中的服務配置

<system.serviceModel>    
<protocolMapping>
      <add scheme="http" binding="wsHttpBinding"/>
    </protocolMapping>
  </system.serviceModel>

新建客戶端(控制檯應用程序)

namespace Client
{
    class Program
    {
        static void Main(string[] args)
        {
            Person[] persons = new Person[]
            {
                new Person{Mark=46,Name="Jim"},
                new Person{Mark=73,Name="Tom"},
                new Person{Mark=92,Name="John"},
                new Person{Mark=84,Name="Geogre"}
            };

            Console.WriteLine("People");
            OutputPeople(persons);

            IAwardService client = ChannelFactory<IAwardService>.CreateChannel(
                new WSHttpBinding(),new EndpointAddress("http://localhost:51425/AwardService.svc"));
            client.SetPassMark(70);

            Person[] awardedPeople = client.GetAwardedPeople(persons);

            Console.WriteLine();
            Console.WriteLine("Award people:");
            OutputPeople(awardedPeople);

            Console.ReadKey();

        }
        static void OutputPeople(Person[] persons)
        {
            foreach (Person person in persons)
            {
                Console.WriteLine("{0},mark:{1}",person.Name,person.Mark);
            }
        }
    }
}
