生成WCF客戶端ppt課件

1、南京工業(yè)職業(yè)技術(shù)學(xué)院生成生成WCFWCF客戶端客戶端蔣美云蔣美云;南京工業(yè)職業(yè)技術(shù)學(xué)院從編程模型上講：WCF經(jīng)過在客戶端生成代理PROXY進(jìn)展效力調(diào)用調(diào)用代理的創(chuàng)建有兩種方法：第一：經(jīng)過ChannelFactory或DuplexChannelFactory直接創(chuàng)建代理對象。第二：ClientBase:經(jīng)過代碼生成器比如：SvcUtil.exe或者添加效力援用導(dǎo)入元數(shù)據(jù)生效果勞代理類,生成的效力代理類承繼自System.ServiceModel.ClientBase。;南京工業(yè)職業(yè)技術(shù)學(xué)院經(jīng)過SVCUTIL.EXE完成操作 SVCUTI

2、L.EXE是一個(gè)命令行工具，位于：C:PROGRAM FILESMICROSOFT SDKSWINDOWSV7.0ABIN目錄下或者運(yùn)用“添加效力援用來完成該步驟;南京工業(yè)職業(yè)技術(shù)學(xué)院創(chuàng)建一個(gè)WCF客戶端;南京工業(yè)職業(yè)技術(shù)學(xué)院小結(jié)無論是直接借助SvcUtil.exe，還是添加效力援用方式，生成的中心類是承繼自system.serviceModel.ClientBase子類，Tchanel為效力契約型類型。比如對于以下契約：namespace Artech.Wcfservices.Client.CalculatorServices ServiceContract interface ICalcu

3、lator OperationContract double Add(double x, double y);上面的代碼會(huì)生成3個(gè)類：ICalculator 、ICalculatorChannel、CalcultorClient。編寫客戶端調(diào)用：Using(CalcultorClient calculator=new CalcultorClient()result=calculator.Add(1,2);南京工業(yè)職業(yè)技術(shù)學(xué)院也可以手工創(chuàng)建效力代理類CALCULTORCLIENTPublic class CalcultatorClient:ClientBase,Icalculator Publi

4、c CalcultatorClient(String endpointName) :base(endpointName) Public Double Add(double x,double y) return this.Channel.Add(x,y); ;南京工業(yè)職業(yè)技術(shù)學(xué)院經(jīng)過實(shí)現(xiàn)CLIENTBASE類編寫一個(gè)WCF客戶端對象1.引入契約 ServiceContract interface IService OperationContract String HelloWorld(String name); ;南京工業(yè)職業(yè)技術(shù)學(xué)院2.添加類，承繼自CLIENTBASE class Hello

5、WorldProxy : ClientBase, IService /硬編碼定義綁定 public static readonly Binding HelloWorldBinding = new NetNamedPipeBinding(); /硬編碼定義地址 public static readonly EndpointAddress HelloWorldAddress=new EndpointAddress(new Uri(net.pipelocalhost/HelloWorld);/構(gòu)造方法public HelloWorldProxy() : base(HelloWorldBinding,

6、 HelloWorldAddress) public String HelloWorld(String name) return Channel.HelloWorld(name); ;南京工業(yè)職業(yè)技術(shù)學(xué)院3.創(chuàng)建代理調(diào)用效力static void Main(string args) using (HelloWorldProxy proxy = new HelloWorldProxy() Console.WriteLine(proxy.HelloWorld(WCF); Console.Read(); ;南京工業(yè)職業(yè)技術(shù)學(xué)院經(jīng)過CHANNELFACTORY或DUPLEXCHANNELFACTORY

7、直接創(chuàng)建代理對象。static void Main(string args) using(ChannelFactory channelF=new ChannelFactory CalculatorServices) ICalcultor calcultor=channel.CreateChannel(); using(caclutor as IDisposable) result=calculator.Add(1,2) 地址和綁定必需在配置文件中。;南京工業(yè)職業(yè)技術(shù)學(xué)院不同寫法：using (ChannelFactory ChannelFactory = new ChannelFactory(

8、new WSHttpBinding(), :9999/CalculatorService) ICalculator proxy = ChannelFactory.CreateChannel(); using (proxy as IDisposable) Console.WriteLine (x+y=0,proxy .Add (1,3); Console.WriteLine(x+y=0, proxy.Subtract(5, 2); Console.WriteLine(x+y=0, proxy.Multiply(2, 3); Console.WriteLine(x+y=0, proxy.Divide(6, 2); Console.ReadLine(); ;南京工業(yè)職業(yè)技術(shù)學(xué)院雙工 InstanceContext instanceContext = new InstanceContext(new CalculateCallback(); using (DuplexChannelFactory ChannelFactory = new DuplexChannelFactory(instanceContex
