Question

我想以编程方式修改我的app.config文件，以设置应该使用哪个服务文件端点。在运行时执行此操作的最佳方法是什么？供参考：

<endpoint address="http://mydomain/MyService.svc"
    binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IASRService"
    contract="ASRService.IASRService" name="WSHttpBinding_IASRService">
    <identity>
        <dns value="localhost" />
    </identity>
</endpoint>

Answer 1

这是客户端吗？

如果是这样，您需要创建一个WsHttpBinding实例和一个EndpointAddress，然后将这两个实例传递给代理客户端构造函数，该构造函数将这两个作为参数。

// using System.ServiceModel;
WSHttpBinding binding = new WSHttpBinding();
EndpointAddress endpoint = new EndpointAddress(new Uri("http://localhost:9000/MyService"));

MyServiceClient client = new MyServiceClient(binding, endpoint);

如果它位于服务器端，那么您需要以编程方式创建自己的ServiceHost实例，并为其添加适当的服务端点。

ServiceHost svcHost = new ServiceHost(typeof(MyService), null);

svcHost.AddServiceEndpoint(typeof(IMyService), 
                           new WSHttpBinding(), 
                           "http://localhost:9000/MyService");

当然，您可以将多个服务端点添加到服务主机中。完成后，您需要通过调用.Open（）方法打开服务主机。

如果您希望能够动态地 - 在运行时 - 选择要使用的配置，您可以定义多个配置，每个配置都有唯一的名称，然后调用相应的构造函数（对于您的服务主机或您的代理客户端）使用您要使用的配置名称。

E.g。你可以轻松拥有：

<endpoint address="http://mydomain/MyService.svc"
        binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IASRService"
        contract="ASRService.IASRService" 
        name="WSHttpBinding_IASRService">
        <identity>
            <dns value="localhost" />
        </identity>
</endpoint>

<endpoint address="https://mydomain/MyService2.svc"
        binding="wsHttpBinding" bindingConfiguration="SecureHttpBinding_IASRService"
        contract="ASRService.IASRService" 
        name="SecureWSHttpBinding_IASRService">
        <identity>
            <dns value="localhost" />
        </identity>
</endpoint>

<endpoint address="net.tcp://mydomain/MyService3.svc"
        binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IASRService"
        contract="ASRService.IASRService" 
        name="NetTcpBinding_IASRService">
        <identity>
            <dns value="localhost" />
        </identity>
</endpoint>

（三个不同的名称，通过指定不同的bindingConfigurations来指定不同的参数），然后选择正确的名称来实例化您的服务器（或客户端代理）。

但在这两种情况下 - 服务器和客户端 - 您必须在实际创建服务主机或代理客户端之前选择。 创建后，这些是不可变的 - 一旦启动并运行，您就无法调整它们。

我使用以下代码更改App.Config文件中的端点地址。您可能希望在使用前修改或删除命名空间。

using System;
using System.Xml;
using System.Configuration;
using System.Reflection;
//...

namespace Glenlough.Generations.SupervisorII
{
    public class ConfigSettings
    {

        private static string NodePath = "//system.serviceModel//client//endpoint";
        private ConfigSettings() { }

        public static string GetEndpointAddress()
        {
            return ConfigSettings.loadConfigDocument().SelectSingleNode(NodePath).Attributes["address"].Value;
        }

        public static void SaveEndpointAddress(string endpointAddress)
        {
            // load config document for current assembly
            XmlDocument doc = loadConfigDocument();

            // retrieve appSettings node
            XmlNode node = doc.SelectSingleNode(NodePath);

            if (node == null)
                throw new InvalidOperationException("Error. Could not find endpoint node in config file.");

            try
            {
                // select the 'add' element that contains the key
                //XmlElement elem = (XmlElement)node.SelectSingleNode(string.Format("//add[@key='{0}']", key));
                node.Attributes["address"].Value = endpointAddress;

                doc.Save(getConfigFilePath());
            }
            catch( Exception e )
            {
                throw e;
            }
        }

        public static XmlDocument loadConfigDocument()
        {
            XmlDocument doc = null;
            try
            {
                doc = new XmlDocument();
                doc.Load(getConfigFilePath());
                return doc;
            }
            catch (System.IO.FileNotFoundException e)
            {
                throw new Exception("No configuration file found.", e);
            }
        }

        private static string getConfigFilePath()
        {
            return Assembly.GetExecutingAssembly().Location + ".config";
        }
    }
}

Answer 3

SomeServiceClient client = new SomeServiceClient();

var endpointAddress = client.Endpoint.Address; //gets the default endpoint address

EndpointAddressBuilder newEndpointAddress = new EndpointAddressBuilder(endpointAddress);
                newEndpointAddress.Uri = new Uri("net.tcp://serverName:8000/SomeServiceName/");
                client = new SomeServiceClient("EndpointConfigurationName", newEndpointAddress.ToEndpointAddress());

我是这样做的。好处是仍然从配置中获取其余的端点绑定设置，只需替换URI 。

Answer 4

这个简短的代码对我有用：

Configuration wConfig = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup wServiceSection = ServiceModelSectionGroup.GetSectionGroup(wConfig);

ClientSection wClientSection = wServiceSection.Client;
wClientSection.Endpoints[0].Address = <your address>;
wConfig.Save();

当然，您必须在配置更改后创建ServiceClient代理。您还需要引用 System.Configuration 和 System.ServiceModel 程序集来实现此功能。

即使没有定义配置部分，这是用于更新应用配置文件的最短代码：

void UpdateAppConfig(string param)
{
   var doc = new XmlDocument();
   doc.Load("YourExeName.exe.config");
   XmlNodeList endpoints = doc.GetElementsByTagName("endpoint");
   foreach (XmlNode item in endpoints)
   {
       var adressAttribute = item.Attributes["address"];
       if (!ReferenceEquals(null, adressAttribute))
       {
           adressAttribute.Value = string.Format("http://mydomain/{0}", param);
       }
   }
   doc.Save("YourExeName.exe.config");
}

Answer 7

我认为您想要的是在运行时更换配置文件的一个版本，如果是这样的话，请创建一个配置文件的副本（也给它相应的扩展名，如.Debug或.Release），它具有正确的地址（它为您提供调试版本和运行时版本）并创建一个postbuild步骤，根据构建类型复制正确的文件。

以下是我过去使用过的postbuild事件示例，该事件使用正确的版本（调试/运行时）覆盖输出文件

copy "$(ProjectDir)ServiceReferences.ClientConfig.$(ConfigurationName)" "$(ProjectDir)ServiceReferences.ClientConfig" /Y

其中： $（ProjectDir）是配置文件所在的项目目录 $（ConfigurationName）是活动配置构建类型

Answer 8

MyServiceClient client = new MyServiceClient(binding, endpoint);
client.Endpoint.Address = new EndpointAddress("net.tcp://localhost/webSrvHost/service.svc");
client.Endpoint.Binding = new NetTcpBinding()
            {
                Name = "yourTcpBindConfig",
                ReaderQuotas = XmlDictionaryReaderQuotas.Max,
                ListenBacklog = 40 }

在配置中修改配置或绑定信息中的uri非常容易。这是你想要的吗？

Answer 9

你可以这样做：

将您的设置保存在单独的xml文件中，并在为服务创建代理时通读它。

例如，我想在运行时修改我的服务端点地址，因此我有以下 ServiceEndpoint.xml 文件。

     <?xml version="1.0" encoding="utf-8" ?>
     <Services>
        <Service name="FileTransferService">
           <Endpoints>
              <Endpoint name="ep1" address="http://localhost:8080/FileTransferService.svc" />
           </Endpoints>
        </Service>
     </Services>

用于阅读xml：

 var doc = new XmlDocument();
 doc.Load(FileTransferConstants.Constants.SERVICE_ENDPOINTS_XMLPATH);
 XmlNodeList endPoints = doc.SelectNodes("/Services/Service/Endpoints");  
 foreach (XmlNode endPoint in endPoints)
 {
    foreach (XmlNode child in endPoint)
    {
        if (child.Attributes["name"].Value.Equals("ep1"))
        {
            var adressAttribute = child.Attributes["address"];
            if (!ReferenceEquals(null, adressAttribute))
            {
                address = adressAttribute.Value;
            }
       }
   }
}

然后在运行时获取客户端的web.config文件，并将服务端点地址指定为：

    Configuration wConfig = ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap { ExeConfigFilename = @"C:\FileTransferWebsite\web.config" }, ConfigurationUserLevel.None);
    ServiceModelSectionGroup wServiceSection = ServiceModelSectionGroup.GetSectionGroup(wConfig);

    ClientSection wClientSection = wServiceSection.Client;
    wClientSection.Endpoints[0].Address = new Uri(address);
    wConfig.Save();

为了它的价值，我需要为我的RESTFul服务更新SSL的端口和方案。这就是我做的。抱歉这是原始问题的一点，但希望对某人有用。

// Don't forget to add references to System.ServiceModel and System.ServiceModel.Web

using System.ServiceModel;
using System.ServiceModel.Configuration;

var port = 1234;
var isSsl = true;
var scheme = isSsl ? "https" : "http";

var currAssembly = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
Configuration config = ConfigurationManager.OpenExeConfiguration(currAssembly);

ServiceModelSectionGroup serviceModel = ServiceModelSectionGroup.GetSectionGroup(config);

// Get the first endpoint in services.  This is my RESTful service.
var endp = serviceModel.Services.Services[0].Endpoints[0];

// Assign new values for endpoint
UriBuilder b = new UriBuilder(endp.Address);
b.Port = port;
b.Scheme = scheme;
endp.Address = b.Uri;

// Adjust design time baseaddress endpoint
var baseAddress = serviceModel.Services.Services[0].Host.BaseAddresses[0].BaseAddress;
b = new UriBuilder(baseAddress);
b.Port = port;
b.Scheme = scheme;
serviceModel.Services.Services[0].Host.BaseAddresses[0].BaseAddress = b.Uri.ToString();

// Setup the Transport security
BindingsSection bindings = serviceModel.Bindings;
WebHttpBindingCollectionElement x =(WebHttpBindingCollectionElement)bindings["webHttpBinding"];
WebHttpBindingElement y = (WebHttpBindingElement)x.ConfiguredBindings[0];
var e = y.Security;

e.Mode = isSsl ? WebHttpSecurityMode.Transport : WebHttpSecurityMode.None;
e.Transport.ClientCredentialType = HttpClientCredentialType.None;

// Save changes
config.Save();
