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" />
         
        <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
