WCF应用的编码实现
先来看看代码,然后再解说一下。
class Program
{
static void Main(string[] args)
{
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
using (ServiceHost serviceHost = new ServiceHost(typeof(ServiceMonitor)))
{
NetNamedPipeBinding binding = new NetNamedPipeBinding();
binding.Security.Mode = NetNamedPipeSecurityMode.None;
binding.ReceiveTimeout = TimeSpan.Parse("00:00:05");
binding.MaxReceivedMessageSize = 6553600;
binding.ReaderQuotas.MaxStringContentLength = 6553600;
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
serviceHost.AddServiceEndpoint(typeof(IMonitor), binding, "net.pipe://localhost/ServiceMonitor");
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
//ServiceMetadataBehavior behavior = serviceHost.Description.Behaviors.Find<ServiceMetadataBehavior>();
//if (behavior == null)
//{
// behavior = new ServiceMetadataBehavior();
// serviceHost.Description.Behaviors.Add(behavior);
//}
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
serviceHost.Opened += delegate
{
Console.WriteLine("正在运行的服务提供IMonitor功能
..");
};
serviceHost.Open();
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
while (true)
{
Console.WriteLine("服务正在运行,要退出请键入exit");
string cmd = Console.ReadLine();
if (cmd == "exit")
break;
}
}
}

static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
Console.WriteLine("刚才的操作发生异常,信息如下:");
Console.Write(e.ToString());
}
}

[ServiceContract]
public interface IMonitor
{
[OperationContract]
void Record(string key, string value);
}
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
public class ServiceMonitor : IMonitor
{
public void Record(string key, string value)
{
Console.WriteLine(string.Format("Key = {0}", key));
Console.WriteLine(string.Format("Value = {0}", value));
Console.WriteLine(new string('*', 50));
}
}
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
public static class ServiceMonitorClientManager
{
public static void Record(string key, string value)
{
try
{
EndpointAddress address = new EndpointAddress("net.pipe://localhost/ServiceMonitor");
NetNamedPipeBinding binding = new NetNamedPipeBinding();
binding.Security.Mode = NetNamedPipeSecurityMode.None;
binding.SendTimeout = TimeSpan.Parse("00:00:01");
binding.ReaderQuotas.MaxStringContentLength = 6553600;
binding.MaxReceivedMessageSize = 6553600;
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
IMonitor iMonitor = ChannelFactory<IMonitor>.CreateChannel(binding, address);
using (iMonitor as IDisposable)
{
iMonitor.Record(key, value);
}
}
catch (System.ServiceModel.CommunicationObjectFaultedException) { }
catch (System.ServiceModel.EndpointNotFoundException) { }
}
}
1、通过using (ServiceHost serviceHost = new ServiceHost(typeof(ServiceMonitor))) 初始化了一个ServiceHost对象,然后通过编码创建ServiceEndpoint然后添加到ServiceHost对象中,根据ABC规则,ServiceEndpoint的创建最少需要传入Contract、Binding、Address,例如:
serviceHost.AddServiceEndpoint(typeof(IMonitor), binding, "net.pipe://localhost/ServiceMonitor");
2、创建ServiceHost后还可以添加相应的IServiceBehavior实现例如:内置的ServiceMetadataBehavior等,也可以创建自定义的Behavior
public class CustomBehavior :IServiceBehavior
可以通过serviceHost.Description.Behaviors.Add(behavior);把内置或或自定义的Behavior添加到ServiceHost中。
3、WCF的客户端代理可以通过ChannelFactory来创建,只要为ChannelFactory<T>.CreateChannel 方法传入Binding和Address参数即可,当然也可以通过
public class ContentReceiverClient : ClientBase<T>, T
如:public class ContentReceiverClient : ClientBase<IMonitor>, IMonitor 方式创建
4、当使用ChannelFactory创建客户代理时请调用IDisposable方法关闭资源
using (iMonitor as IDisposable)
如果使用Client : ClientBase<T>, T 创建客户代理如:
base.Channel.接口方法
则需要在调用完后Client.Close()关闭资源。
