命令性示例演示如何使用代码为服务定义 WSHttpBinding，而不是在配置中定义 wsHttpBinding 绑定。 此示例基于实现计算器服务的入门指南。

注意

本主题的最后介绍了此示例的设置过程和生成说明。

下面的代码演示如何在代码中强制定义绑定。

public static void Main()
{
    WSHttpBinding binding = new WSHttpBinding();
    binding.Name = "binding1";
    binding.HostNameComparisonMode =
        HostNameComparisonMode.StrongWildcard;
    binding.Security.Mode = SecurityMode.Message;
    binding.ReliableSession.Enabled = false;
    binding.TransactionFlow = false;

    Uri baseAddress =
        new Uri("http://localhost:8000/servicemodelsamples/service");

    // Create a ServiceHost for the CalculatorService type and provide the base address.
    using(ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService), baseAddress))
    {
        serviceHost.AddServiceEndpoint(typeof(ICalculator),
                                       binding, baseAddress);
        // Open the ServiceHostBase to create listeners and start listening for messages.
        serviceHost.Open();

        // The service can now be accessed.
        Console.WriteLine("The service is ready.");
        Console.WriteLine("Press <ENTER> to terminate service.");
        Console.WriteLine();
        Console.ReadLine();
        // Close the ServiceHostBase to shutdown the service.
        serviceHost.Close();
    }
}

客户端创建一个用来与服务进行通信的通道，如下面的示例代码所示。

WSHttpBinding binding = new WSHttpBinding();
binding.Name = "binding1";
binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
binding.Security.Mode = SecurityMode.Message;
binding.ReliableSession.Enabled = false;
binding.TransactionFlow = false;

String url = "http://localhost:8000/servicemodelsamples/service";
EndpointAddress address = new EndpointAddress(url);
ChannelFactory<ICalculator> channelFactory = new ChannelFactory<ICalculator>(binding,address);
ICalculator channel = channelFactory.CreateChannel();

运行示例时，操作请求和响应将显示在客户端控制台窗口中。 在客户端窗口中按 Enter 可以关闭客户端。

Add(100,15.99) = 115.99
Subtract(145,76.54) = 68.46
Multiply(9,81.25) = 731.25
Divide(22,7) = 3.14285714285714

Press <ENTER> to terminate client.
