命令式

這個範例示範如何使用程式碼以定義服務的 WsHttpBinding，而不是使用組態來定義 wsHttpBinding 繫結的方式。這個範例是以實作計算機服務的使用者入門範例為基礎。

注意：
此範例的安裝程序與建置指示位於本主題的結尾。

下列程式碼示範如何透過程式碼來命令式地定義繫結。

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("https://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();                      
    }           
}

用戶端會建立要與服務通訊的通道，如下列範例程式碼所示。

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

當您執行範例時，作業要求和回應會顯示在用戶端主控台視窗中。在用戶端視窗中按下 ENTER 鍵，即可關閉用戶端。

    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.

若要設定、建置及執行範例

1. 請確定您已執行 Windows Communication Foundation 範例的單次安裝程序。

2. 若要建置方案的 C# 或 Visual Basic .NET 版本，請遵循建置 Windows Communication Foundation 範例中的指示。

3. 若要在單一或跨電腦的組態中執行本範例，請遵循執行 Windows Communication Foundation 範例中的指示。
