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
