WCF分布式开发步步为赢系列的(4)：WCF服务可靠性传输配置与编程开发
【3】编程方式实现可靠性传输：
至于编程配置方式，这里我们稍作介绍，TCP绑定和WS绑定提供了略微不同的属性来配置可靠性。这里的例子我们继续使用的是针对TCP编程实现可靠性传输的示例代码：
//采用自托管方式，也可以是IIS、WAS,Windows服务等用户自定义程序托管服务
public class WCFHost
{
static void Main(string[] args)
{
//反射方式创建服务实例，
//Using方式生命实例，可以在对象生命周期结束时候，释放非托管资源
using (ServiceHost host = new ServiceHost(typeof(WCFService.WCFService)))
{
//相同的服务注册多个基地址
//添加服务和URI，用户资源标识符
Uri tcpAddress = new Uri("net.tcp://localhost:8001/WCFService");
//Uri httpAddress = new Uri("http://localhost:8002/WCFService");
//Uri pipeAddress = new Uri("net.pipe://localhost:8002/WCFService");
SecurityMode securityMode = new SecurityMode();//实例化安全模型
//设置可靠性会话为真
NetTcpBinding netTcpBinding = new NetTcpBinding(securityMode, true);
//添加服务终结点，方式不变
host.AddServiceEndpoint(typeof(WCFService.IWCFService), netTcpBinding, tcpAddress);
//host.AddServiceEndpoint(typeof(WCFService.IWCFService), new WSHttpBinding(), httpAddress);
//host.AddServiceEndpoint(typeof(WCFService.IWCFService), new NetNamedPipeBinding(), pipeAddress);
////判断是否以及打开连接，如果尚未打开，就打开侦听端口
if (host.State != CommunicationState.Opening)
host.Open();
//显示运行状态
Console.WriteLine("Host is runing! and state is {0}", host.State);
//等待输入即停止服务
Console.Read();
}
}
public class WCFHost
{
static void Main(string[] args)
{
//反射方式创建服务实例，
//Using方式生命实例，可以在对象生命周期结束时候，释放非托管资源
using (ServiceHost host = new ServiceHost(typeof(WCFService.WCFService)))
{
//相同的服务注册多个基地址
//添加服务和URI，用户资源标识符
Uri tcpAddress = new Uri("net.tcp://localhost:8001/WCFService");
//Uri httpAddress = new Uri("http://localhost:8002/WCFService");
//Uri pipeAddress = new Uri("net.pipe://localhost:8002/WCFService");
SecurityMode securityMode = new SecurityMode();//实例化安全模型
//设置可靠性会话为真
NetTcpBinding netTcpBinding = new NetTcpBinding(securityMode, true);
//添加服务终结点，方式不变
host.AddServiceEndpoint(typeof(WCFService.IWCFService), netTcpBinding, tcpAddress);
//host.AddServiceEndpoint(typeof(WCFService.IWCFService), new WSHttpBinding(), httpAddress);
//host.AddServiceEndpoint(typeof(WCFService.IWCFService), new NetNamedPipeBinding(), pipeAddress);
////判断是否以及打开连接，如果尚未打开，就打开侦听端口
if (host.State != CommunicationState.Opening)
host.Open();
//显示运行状态
Console.WriteLine("Host is runing! and state is {0}", host.State);
//等待输入即停止服务
Console.Read();
}
}
SecurityMode securityMode = new SecurityMode();这个语句就是实例化安全模型，NetTcpBinding netTcpBinding = new NetTcpBinding(securityMode, true);传入的参数为true，就是启用可靠性传递。添加服务终结点，方式不变host.AddServiceEndpoint(typeof(WCFService.IWCFService), netTcpBinding, tcpAddress);这样就编程实现了TCP消息的可靠性传递。
