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
