最近公司把我分配到了数据组，个人也被分配到了数据住主管同步数据，主要负责用WCf开发大同步数据，开始学习！！！
统计应该有四点可以借鉴：1、统一性2、互操作性3、安全与可信赖4、兼容性
借引：简单的订票服务
示例代码Iservice1.cs即为服务契约接口文件，服务要实现的操作可以通过接口来定义
using System;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.ServiceModel;
namespace WcfService1
{
//注意:如果更改此处的接口名称"IService1"，也必须更新Web.config中对"IService1"的引用。
[ServiceContract]
public interface IService1
{
[OperationContract]
int GetRemainingNum();
[OperationContract]
List<Tickets> BuyTickets(int Num);
}
// 服务契约数据定义
[DataContract]
public class Tickets
{
//假设还有1张,编号是"23"
int remainingNum = 1;
string ticketID = "23";
/// <summary>
/// 剩余数量
/// </summary>
[DataMember]
public int RemainingNum
{
get { return remainingNum; }
set { remainingNum = value; }
}
/// <summary>
/// 车票编号
/// </summary>
[DataMember]
public string TicketID
{
get { return ticketID; }
set { ticketID = value; }
}
}
}
服务实现起始就是对契约（接口）的实现，继承接口并实现方法
using System;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.ServiceModel;
namespace WcfService1
{
// 注意: 如果更改此处的类名“Service1”，
//也必须更新Web.config和关联的.svc文件中对“Service1”的引用
public class Service1 : IService1
{
//查询剩余数量
public int GetRemainingNum()
{
Tickets tic = new Tickets();
return tic.RemainingNum;
}
//购买票
public List<Tickets> BuyTickets(int Num)
{
//自己的业务逻辑代码实现，这里只是举例
Tickets tick = new Tickets();
if (Num > 0)
{
tick.RemainingNum--;
}
List<Tickets> ticklist = new List<Tickets>();
ticklist.Add(tick);
return ticklist;
}
}
}
宿主进程：要想使wcf服务运行，需要宿主进程，即wcf服务不可能凭空存在。每个wcf服务必须托管hosting在windows进程中，该进程就称为宿主进程。宿主可以有iis提供，也可以有windows form 程序或windows 服务提供，或者有 console 控制台程序提供。
配置文件：对刚才实现的wcf服务的库引用：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<service name="WcfService1.Service1" behaviorConfiguration="CalculatorServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/"/>
</baseAddresses>
</host>
<endpoint address="" binding="wsHttpBinding" contract="WcfService1.IService1" />
</service>
</services>
<!--为了调试,设置 includeExceptionDetailInFaults 属性等于true.-->
<behaviors>
<serviceBehaviors>
<behavior name="CalculatorServiceBehavior">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
启动服务：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Windows.Forms;
using System.ServiceModel;
namespace WindowsFormsWcfApp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
//声明宿主
ServiceHost host =null;
private void btnStart_Click(object sender, EventArgs e)
{
host = new ServiceHost(typeof(WcfService1.Service1));
host.Open();//启动服务的监听器信道，监听请求
//host.AddServiceEndpoint(typeof(IMyProcess), new BasicHttpBinding(), "manualWCF"); //ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
//smb.HttpGetEnabled = true;
//host.Description.Behaviors.Add(smb);
label1.Text = "订票服务已启动";
}
private void btnStop_Click(object sender, EventArgs e)
{
if (host.State != CommunicationState.Closed)
{
host.Close();//停止信道
}
label1.Text = "订票服务已停止";
}
}
}
调用服务：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WCFClientApp
{
public partial class Form1 : Form
{
public Form1()
{ InitializeComponent(); }
private void button1_Click(object sender, EventArgs e)
{
TicketServiceRef.Service1Client wcfClient = new TicketServiceRef.Service1Client();
int n=wcfClient.GetRemainingNum();//查询剩余数量
TicketServiceRef.Tickets[] tickets=wcfClient.BuyTickets(1);//购买一张票
}
}
}
