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"


OK
