VS2010 创建WCF以及SL的客户端如何调用WCF服务教程(一): 创建WCF

经过一整天的自我摸索, 终于搞定SL如何调用WCF, ⊙�n⊙b汗.

谨以此文纪念.

1. 打开VS2010， 点击"File/New/Project"
2. 点击左边"Other Languages/Visual C#", 选择右边的"WCF Service Application", 如图:

       

  3. 设置好工程名字和路径后, 点击"Ok”后, vs2010默认生成了一个简单的Service, 代码如下:

定义服务契约

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together. [ServiceContract] public interface IService1 { [OperationContract] string GetData( int value); [OperationContract] CompositeType GetDataUsingDataContract(CompositeType composite); // TODO: Add your service operations here } // Use a data contract as illustrated in the sample below to add composite types to service operations. [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; } } }

实现服务契约

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together. public class Service1 : IService1 { 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. F7编译后, F5运行, 效果如下:

 

(P.S. Windows Communication Foundation (WCF) 测试客户端 (WcfTestClient.exe) 是一个 GUI 工具，使用该工具，用户可以输入测试参数、将该输入提交给服务并查看服务发回的响应。当与 WCF 服务主机结合时，它可以提供完美的服务测试体验。)

  5. 经过前面的几个步骤, 我们已经建立了一个可以供Silverlight测试使用的Service.

 

  下一节, 我将给大家讲解如何在SL中调用此Service.
