您可以覆盖 system.serviceModel 配置部分吗？答案

【问题标题】：Can you override system.serviceModel configuration section?您可以覆盖 system.serviceModel 配置部分吗？

【问题描述】：

我们正在尝试创建一个“代理”类，该类将通过其配置属性为 WCF 服务提供服务。

因为我们无法将这些属性存储在 app.config 文件中，所以我正在寻找一种方法来“代理”它并使用自定义 configurationSection 来根据请求提供所有这些数据。为此，我需要告诉 .NET 框架使用我自己的 ConfigurationSection 加载 system.serviceModel，但我不确定我是否能做到。

如果有人可以批准我的假设，甚至更好，请告诉我如何使用其他来源配置 WCF 设置，这将很有帮助。

谢谢

【解决方案1】：

如果您正在寻找在代码中创建和注册 wcf 服务的方法，请查看以下代码以获取示例：

下面是创建服务宿主对象的方法：

public static ServiceHost RegisterService<T>(object service, int port, string serviceName)
{
    // Returns a list of ipaddress configuration
    IPHostEntry ips = Dns.GetHostEntry(Dns.GetHostName());

    // Select the first entry. I hope it's this maschines IP
    IPAddress ipAddress = ips.AddressList[0];

    // Create the url that is needed to specify where the service should be started
    string urlService = "net.tcp://" + ipAddress.ToString() + String.Format(":{0}/{1}", port, serviceName);

    // Instruct the ServiceHost that the type that is used is a ServiceLibrary.service1
    ServiceHost host = new ServiceHost(service);
    // define events if needed
    //host.Opening += new EventHandler(HostOpeningEvent);
    //host.Opened += new EventHandler(HostOpenedEvent);
    //host.Closing += new EventHandler(HostClosingEvent);
    //host.Closed += new EventHandler(HostClosedEvent);

    // The binding is where we can choose what transport layer we want to use. HTTP, TCP ect.
    NetTcpBinding tcpBinding = new NetTcpBinding();
    tcpBinding.TransactionFlow = false;
    tcpBinding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign;
    tcpBinding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;
    tcpBinding.Security.Mode = SecurityMode.None; 

    // Add a endpoint
    host.AddServiceEndpoint(typeof(T), tcpBinding, urlService);

    // A channel to describe the service. Used with the proxy scvutil.exe tool
    ServiceMetadataBehavior metadataBehavior;
    metadataBehavior = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
    if (metadataBehavior == null)
    {
        string httpURL = "http://" + ipAddress.ToString() + String.Format(":{0}/{1}", port + 1, serviceName);

        // This is how I create the proxy object that is generated via the svcutil.exe tool
        metadataBehavior = new ServiceMetadataBehavior();
        metadataBehavior.HttpGetUrl = new Uri(httpURL);
        metadataBehavior.HttpGetEnabled = true;
        metadataBehavior.ToString();
        host.Description.Behaviors.Add(metadataBehavior);
    }
    return host;
}

你可以这样使用它：

ServiceHost host = RegisterService<your_service_interface>(your_service, port, "yout_service_name");
host.Open();

希望这会有所帮助，问候
