命令式

命令式範例示範如何使用程式代碼來定義WSHttpBinding 服務的某個組件，而不是在組態中定義wsHttpBinding連接。 這個範例是以實作計算機服務的使用者入門範例為基礎。

備註

此範例的安裝程式和建置指示位於本主題結尾。

下列程式代碼示範如何在程式代碼中以命令方式定義系結。

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("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();
    }
}

用戶端會建立通道來與服務通訊，如下列範例程式代碼所示。

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 = "http://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控制台視窗中。 在客戶端視窗中按 ENTER 鍵以關閉用戶端。

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.

要設定、建置和執行範例，請執行以下步驟：

1. 請確定您已針對 Windows Communication Foundation 範例執行One-Time 安裝程式。

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

3. 若要在單一或跨計算機組態中執行範例，請遵循執行 Windows Communication Foundation 範例 中的指示。
