WCF(Windows Communication Foundation) - 廢話不多說,俗也不能免,我也從Hello開始
示例
1、服務
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類
/// </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方式提供服務--> <serviceMetadata httpGetEnabled="true" /> </behavior> </serviceBehaviors> </behaviors> <services> <!--name - 提供服務的類名--> <!--behaviorConfiguration - 指定相關的行為配置--> <service name="WCF.ServiceLib.Sample.Hello" behaviorConfiguration="SampleBehavior"> <!--address - 服務地址--> <!--binding - 通信方式--> <!--contract - 服務契約--> <endpoint address="" binding="basicHttpBinding" contract="WCF.ServiceLib.Sample.IHello" /> </service> </services> </system.serviceModel> </configuration>
3、客戶端
Hello.aspx
<%@ Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Hello.aspx.cs" Inherits="Sample_Hello" Title="不能免俗,我也從Hello開始" %> <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 - 服務地址--> <!--binding - 通信方式--> <!--contract - 服務契約--> <endpoint address="http://localhost:3502/ServiceHost/Sample/Hello.svc" binding="basicHttpBinding" contract="Sample.IHello" /> </client> </system.serviceModel> </configuration>
運行結果:
單擊"btnSayHello"後彈出提示框,顯示"Hello: webabcd"
OK
