化零为整WCF(1) - 不能免俗，我也从Hello开始

作者： webabcd


介绍
WCF(Windows Communication Foundation) - 废话不多说，俗也不能免，我也从Hello开始


示例
1、服务
IHello.cs

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

using  System.ServiceModel;

namespace  WCF.ServiceLib.Sample
{
    /**//// <summary>
    /// IHello接口
    /// </summary>
    [ServiceContract]
    public interface IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        [OperationContract]
        string SayHello(string name);
    }
}

Hello.cs

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

using  System.ServiceModel;

namespace  WCF.ServiceLib.Sample
{
    /**//// <summary>
    /// Hello类
    /// </summary>
    public class Hello : IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        public string SayHello(string name)
        {
            return "Hello: " + name;
        }
    }
}

2、宿主
Hello.svc

<% @ ServiceHost Language="C#" Debug="true" Service="WCF.ServiceLib.Sample.Hello"  %>

Web.config

<? xml version="1.0" ?>
< configuration >
   < system .serviceModel >
     < behaviors >
       < serviceBehaviors >
         < behavior  name ="SampleBehavior" >
           <!-- httpGetEnabled - 使用get方式提供服务 -->
           < serviceMetadata  httpGetEnabled ="true"   />
         </ behavior >
       </ serviceBehaviors >
     </ behaviors >
     < services >
       <!-- name - 提供服务的类名 -->
       <!-- behaviorConfiguration - 指定相关的行为配置 -->
       < service  name ="WCF.ServiceLib.Sample.Hello"  behaviorConfiguration ="SampleBehavior" >
         <!-- address - 服务地址 -->
         <!-- binding - 通信方式 -->
         <!-- contract - 服务契约 -->
         < endpoint  address =""  binding ="basicHttpBinding"  contract ="WCF.ServiceLib.Sample.IHello"   />
       </ service >
     </ services >
   </ system.serviceModel >
</ configuration >

3、客户端
Hello.aspx

<% @ Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Hello.aspx.cs"
    Inherits="Sample_Hello" Title="不能免俗，我也从Hello开始"  %>

< asp:Content  ID ="Content1"  ContentPlaceHolderID ="head"  runat ="Server" >
</ asp:Content >
< asp:Content  ID ="Content2"  ContentPlaceHolderID ="ContentPlaceHolder1"  runat ="Server" >
     < asp:TextBox  ID ="txtName"  runat ="server"  Text ="webabcd"   />
     &nbsp;
     < asp:Button  ID ="btnSayHello"  runat ="server"  Text ="Hello"  OnClick ="btnSayHello_Click"   />
</ asp:Content >

Hello.aspx.cs

using  System;
using  System.Collections;
using  System.Configuration;
using  System.Data;
using  System.Linq;
using  System.Web;
using  System.Web.Security;
using  System.Web.UI;
using  System.Web.UI.HtmlControls;
using  System.Web.UI.WebControls;
using  System.Web.UI.WebControls.WebParts;
using  System.Xml.Linq;

public   partial   class  Sample_Hello : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void btnSayHello_Click(object sender, EventArgs e)
    {
        Sample.HelloClient proxy = new Sample.HelloClient();

        Page.ClientScript.RegisterStartupScript(
            this.GetType(),
            "js",
            string.Format("alert('{0}')", proxy.SayHello(txtName.Text)),
            true);

        proxy.Close();
    }
}

Web.config

<? xml version="1.0" ?>
< configuration >
   < system .serviceModel >
     < client >
       <!-- address - 服务地址 -->
       <!-- binding - 通信方式 -->
       <!-- contract - 服务契约 -->
       < endpoint  address ="http://localhost:3502/ServiceHost/Sample/Hello.svc"  binding ="basicHttpBinding"  contract ="Sample.IHello"   />
     </ client >
   </ system.serviceModel >
</ configuration >

运行结果：
单击" btnSayHello"后弹出提示框，显示"Hello: webabcd"
