WCF之HelloWorld

1、wcf之helloworld 不说闲话了，直接hello了。创建服务1、  选择file->new->project->empty project创建一空项目，把solution命名为wcfhello。2、  右击wcfhello项目，add->new item添加接口ihello。在属性页把output type改为class library。3、  在接口中添加一方法，public interface ihelloservice string helloworld(); 4、  add references添加对程序集syst

2、em.servicemodel的引用。using system.servicemodel;5、  用servicecontractattribute修饰ihello接口使其成为服务契约，同时用operationcontractattribute修饰方法helloworld()，使其包含在服务契约中。 servicecontract(namespace=" public interface ihelloservice operationcontract string helloworld(); 6、  添加服务类helloservice.cs。 

3、 public class helloservice: ihelloservice public string helloworld() return "helloworld_wcf" 寄存服务1、  添加console application项目，命名为hellohost。2、  引用system.servicemodel程序集。3、  添加引用项目wcfhello。 using system;using system.servicemodel;using wcfhello;namespace hellohost class pro

4、gram static void main(string args) using (servicehost host = new servicehost(typeof(helloservice), new uri("http:/localhost:8000/hellowcf") host.addserviceendpoint(typeof(ihelloservice), new basichttpbinding(), "hellowcf"); host.open(); console.writeline("hello service is ru

5、nning."); console.readline(); 创建代理调用服务1、  添加一console application项目，命名为helloclient。2、  引用system.servicemodel程序集。3、  复制契约到客户端ihelloservice。 using system.servicemodel;namespace helloclient servicecontract(namespace = " public interface ihelloservice operationcontract strin

6、g helloworld(); using system;using system.servicemodel;namespace helloclient class program static void main(string args) endpointaddress epaddr = new endpointaddress("http:/localhost:8000/hellowcf/helloservice"); ihelloservice proxy = channelfactory<ihelloservice>.createchannel(new b

7、asichttpbinding(), epaddr); console.writeline(proxy.helloworld(); console.writeline("client is running."); console.readline(); 运行结果如下：查看helloservice元数据，修改hellohost项目如下：static void main(string args) using (servicehost host = new servicehost(typeof(helloservice), new uri("http:/localhos

8、t:8000/hellowcf") host.addserviceendpoint(typeof(ihelloservice), new basichttpbinding(), "helloservice"); servicemetadatabehavior behavior = new servicemetadatabehavior(); behavior.httpgetenabled = true; host.description.behaviors.add(behavior); host.addserviceendpoint(typeof(imetadat

9、aexchange), metadataexchangebindings.createmexhttpbinding(), "mex"); host.open(); console.writeline("hello service is running."); console.readline(); 运行服务器端服务，在浏览器重查看元数据如图servicemodel metadata utilityservicemodel metadata utility是一个命令工具，叫做svcutil.exe的可执行文件，用它可以生成客户端代理类和配置文件，如图执行后

10、在“d:visual studio 2010projectswcfhellohelloclient”下面生成一个app.config配置文件和serviceproxy.cs类。app.config的内容如：而后修改客户端代码：static void main(string args) /endpointaddress epaddr = new endpointaddress("http:/localhost:8000/hellowcf/helloservice"); /ihelloservice proxy = channelfactory<ihelloservice>.createchannel(new basichttpbinding(), epaddr); hellose
