------------------------windowform承载服务步骤:
(1)定义契约:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace IWpf
{
[ServiceContract]
public interface IUser
{
[OperationContract]
string GetName();
[OperationContract]
int GetAge();
}
}
(2)承载契约;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using IWpf;
namespace wpf承载服务
{
public class wpf:IUser
{
#region IUser 成员
public string GetName()
{
return "郭泽峰";
}
public int GetAge()
{
return 13;
}
#endregion
}
}
appconfig:配置契约:
?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<service name="wpf承载服务.wpf" behaviorConfiguration ="behaviorone">
<host>
<baseAddresses>
<add baseAddress="http://localhost:1234/wpf"/>
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding" contract="IWpf.IUser">
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="behaviorone">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
-------------启动服务;
using System.ServiceModel;
namespace wpf承载服务
{
public partial class Form1 : Form
{
ServiceHost host;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
host = new ServiceHost(typeof(wpf));
host.Open();
}
private void button2_Click(object sender, EventArgs e)
{
host.Close();
}
}
}
-----------------使用契约;
ServiceReference1.UserClient u = new ServiceReference1.UserClient();
MessageBox.Show(u.GetName());
---------------------------------------------------------------------------完成;
--------------
---------------通过编程来承载和使用服务;
--承载服务
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
ServiceHost host = null;
private void button1_Click(object sender, EventArgs e)
{
host = new ServiceHost(typeof(wpf));
//定义绑定协议:
NetTcpBinding tcpBinding = new NetTcpBinding();
//定义地址:
string s = "net.tcp://localhost:3200/gg";//路径随便了;
host.AddServiceEndpoint(typeof(IWpf.IUser), tcpBinding, s);
host.Opened += delegate { label1.Text = "已经打开"; };
host.Closed += delegate { label1.Text = "已经关闭"; };
host.Open();
}
private void button2_Click(object sender, EventArgs e)
{
if (host.State == CommunicationState.Opened)
{
host.Close();
}
}
-----------------应用客户端:
//绑定形式:
NetTcpBinding bind = new NetTcpBinding();
//地址
EndpointAddress address = new EndpointAddress("net.tcp://localhost:3200/gg");
//通道工厂
ChannelFactory<IWpf.IUser> factory = new ChannelFactory<IWpf.IUser>(bind, address);
IWpf.IUser user = factory.CreateChannel();
string s = user.GetName();
MessageBox.Show(s);
-----------------通信方式:单工(无需等待方法名void,且参数部位out;ref;);请求响应(需要等待);双攻;
单工:[OperationContract(IsOneWay=true)]即可;

---SOA:属于一种基于组件的架构模型;它可以根据需求对松散耦合的粗粒度应用组件
进行分布式部署,组合和使用。
SOA的四个特性:
1.每个服务必须有明确的服务边界;
2.服务是独立的;
3.采用标准的契约定义和通信协议;
4.服务是自解释的;
//地址:
http://dddd:5050/;
net.tcp:dec:3030/myservice;
net.msmq:localhost/mymsmq;
-----------------------------------------
soa的好处:在用户层和一万五层添加了一层服务层,将
力度比较小的互操作的对象进一步封装,形成粗粒度
组件,从而达到一种松耦合的状态;
--------------------------------------------
tcp:二进制;效率远远高于http;多用于内网传输;
http:soap;
---------------------------------------------
wcf:
1.面向服务;
2.松耦合;
3,可交互;
4.整合性;
-----------------------------------------
remoting和wevservice区别:
webservice:不限平台,http协议,基于xml;效率低;无状态;
remoting:仅限。net平台,网络传输协议(不一定是http),二进制;效率很高;有状态;
remoting是.net 中用来跨越machine, process, appdomain 进行方法调用的技术,
------------messagecontract:控制soap协议的工具;
