}}3、使用svcutil 生成WCF客户端
打开Visual Studio 2008 Command Prompt
d:
cd temp
svcutil /language:c# /out:NotifyServiceClient.cs /config:app.config http://localhost:8000/Service/NotifyService.svc
4、手工书写WCF客户端
public class CacheNotifiedUserClient : ClientBase<ICacheNotifiedUser>, ICacheNotifiedUser { public CacheNotifiedUserClient() : base() { } public CacheNotifiedUserClient(InstanceContext callbackInstance) : base(callbackInstance) { } public CacheNotifiedUserClient(string endpointConfigurationName) : base(endpointConfigurationName) { } public CacheNotifiedUserClient(Binding binding, EndpointAddress remoteAddress) : base(binding, remoteAddress) { } public CacheNotifiedUserClient(InstanceContext callbackInstance, string endpointConfigurationName) : base(callbackInstance, endpointConfigurationName) { } public CacheNotifiedUserClient(string endpointConfigurationName, EndpointAddress remoteAddress) : base(endpointConfigurationName, remoteAddress) { } public CacheNotifiedUserClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { } public CacheNotifiedUserClient(InstanceContext callbackInstance, Binding binding, EndpointAddress remoteAddress) : base(callbackInstance, binding, remoteAddress) { } public CacheNotifiedUserClient(InstanceContext callbackInstance, string endpointConfigurationName, EndpointAddress remoteAddress) : base(callbackInstance, endpointConfigurationName, remoteAddress) { } public CacheNotifiedUserClient(InstanceContext callbackInstance, string endpointConfigurationName, string remoteAddress) : base(callbackInstance, endpointConfigurationName, remoteAddress) { } public void Dispose() { this.Close();} public bool Contains(string userName) { return this.Channel.Contains(userName); } }5、如何方便地自动生成WCF客户端及配置文件。
A、设置VS2008 X86 tools的环境：Call "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86
B、svcutil /language:c# /out:NotifyServiceClient.cs /config:app.config http://localhost:8000/Service/NotifyService.svc
C、写成一个生成后事件
