2.系统自动生成IWcfService
// 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IService1”。 [ServiceContract] public interface IWcfService { [OperationContract] string GetData(int value); [OperationContract] CompositeType GetDataUsingDataContract(CompositeType composite); // TODO: 在此添加您的服务操作 } // 使用下面示例中说明的数据约定将复合类型添加到服务操作。 [DataContract] public class CompositeType { bool boolValue = true; string stringValue = "Hello "; [DataMember] public bool BoolValue { get { return boolValue; } set { boolValue = value; } } [DataMember] public string StringValue { get { return stringValue; } set { stringValue = value; } } }
（1）服务契约：ServiceContract（服务）和OperationContract （方法）
（2）数据契约：DataContract（类）和DataMember（属性） 用于类和结构上
（3）消息契约：MessageContract 用于soap消息
3.WCF服务类
public class WcfService : IWcfService { public string GetData(int value) { return string.Format("You entered: {0}", value); } public CompositeType GetDataUsingDataContract(CompositeType composite) { if (composite == null) { throw new ArgumentNullException("composite"); } if (composite.BoolValue) { composite.StringValue += "Suffix"; } return composite; } }
4.服务配置文件
<system.serviceModel> <!--配置绑定节点Start--> <bindings> <basicHttpBinding> <binding maxReceivedMessageSize="2147483647"> <readerQuotas maxStringContentLength="2147483647"/> <security mode="None" /> </binding> </basicHttpBinding> <netTcpBinding> <binding maxReceivedMessageSize="2147483647"> <readerQuotas maxStringContentLength="2147483647"/> <security mode="None" /> </binding> </netTcpBinding> <wsHttpBinding></wsHttpBinding> </bindings> <!--配置绑定节点End--> <!--配置服务节点Start--> <services> <!--配置某一服务，在这里可以指定服务名称--> <service> <endpoint address="aaa" binding="basicHttpBinding" bindingConfiguration="basicHttpBinding0" contract="WcfServiceTest.IWcfService"> <identity> <dns value="localhost"/> </identity> </endpoint> <endpoint address="" binding="netTcpBinding" bindingConfiguration="netTcpBinding0" contract="WcfServiceTest.IWcfService"> <identity> <dns value="localhost"/> </identity> </endpoint> </service> </services> <!--配置服务节点End--> <behaviors> <serviceBehaviors> <behavior> <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false --> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/> <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 --> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <protocolMapping> <add binding="basicHttpsBinding" scheme="https" /> </protocolMapping> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel>
5.iis部署WCF服务
6.添加客户端项目并添加服务引用
7.Main程序中添加wcf服务并调用方法
class Program { static void Main(string[] args) { var client = new WcfService.WcfServiceClient(); try { var str = client.GetData(2046); Console.WriteLine(string.Format("内容:{0}", str)); client.Close(); } catch (Exception ex) { Console.WriteLine("出现异常！"); client.Abort(); } Console.ReadLine(); } }
8.客户端配置文件
<system.serviceModel> <bindings> <basicHttpBinding> <binding /> </basicHttpBinding> <netTcpBinding> <binding> <security mode="None" /> </binding> </netTcpBinding> </bindings> <client> <!--<endpoint address="http://localhost/WcfServiceTest/WcfService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_WcfService" contract="WcfService.IWcfService" />--> <endpoint address="net.tcp://localhost/WcfServiceTest/WcfService.svc" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_WcfService" contract="WcfService.IWcfService"> <identity> <dns value="localhost" /> </identity> </endpoint> </client> </system.serviceModel>
