如何从app.config中读取终结点值并将其传递给客户端的代理类？

Question

I have a service host and its app.config is below:

<system.serviceModel>
 <bindings>
  <netTcpBinding>
    <binding name="NetTcpBinding_ISimSession" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="104857600" maxConnections="10" maxReceivedMessageSize="104857600">          
    </binding>

    <binding name="NetTcpBinding_ISimExportImportSession" closeTimeout="00:10:00" openTimeout="00:10:00"
           receiveTimeout="00:10:00" sendTimeout="00:10:00" transactionFlow="false" transferMode="Streamed"
           hostNameComparisonMode="StrongWildcard"
           maxBufferSize="2147483647"
           maxBufferPoolSize="2147483647"
           maxReceivedMessageSize="2147483647">         

    </binding>
  </netTcpBinding>
</bindings>

<services>
  <service name="SimCentral.Server.SimSession">
    <endpoint address="net.tcp://localhost:8732/Design_Time_Addresses/NextGenService/SimSession/" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_ISimSession"
              contract="NextGenServices.Contract.ISimSessionService.ISimSession">
      <identity>
        <dns value=""/>
      </identity>
    </endpoint>
    <endpoint address="net.tcp://localhost:8735/Design_Time_Addresses/NextGenService/SimExportImportSession/" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_ISimExportImportSession"
              contract="NextGenServices.Contract.ISimSessionService.ISimExportImportSession">
      <identity>
        <dns value=""/>
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8732/Design_Time_Addresses/NextGenService/SimSession/"/>
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior>

      <serviceMetadata httpGetEnabled="false"/>

      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

Now, in the client side, I want to create an instance for the proxy class and call the methods of my application. However, my proxy class constructor is taking 2 parameters binding and endpoint which is taking from the app config file above.

// constructor for the proxy
public SimSessionServiceReferenceProxyObject(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress)
        {
            ....
        }

Question is, how am I gonna get the binding and remoteAddress value from the app.config above to pass it to the constructor ? Consider remoteAddress will be the first endpoint of all 3 endpoints in the app.config. Thank you.

I have use following code to access the end point address. This might help you.

string crmAppSvcEndpointAddrTemplate = null;
        var serviceModelClientConfigSection = ConfigurationManager.GetSection("system.serviceModel/client") as ClientSection;
        foreach (ChannelEndpointElement endpoint in serviceModelClientConfigSection.Endpoints)
        {
            if (endpoint.Name == "MyService")
            {
                crmAppSvcEndpointAddrTemplate = endpoint.Address.ToString();
                break;
            }
        }
