WCF Configuration enhancement

WCF Configuration Enhancement

Background:

In app.config or web.config one may define a config entry in: 

<appSettings>...</appSettings>

like so: 

<add key="MyKey" value="%SomeEnvironmentVariable%"/>

Thereafter in order to retrieve the value associated with MyKey one may employ the following two lines of code:

string raw = ConfigurationManager.AppSettings[“MyKey”];

string cooked = (raw == null) ? null : Environment.ExpandEnvironmentVariables(raw);

Question:

Is there a way to do the same with the WCF service configuration, for example:

<system.serviceModel>
    . . .
    <services>
        <service name="..." ...>
          . . .
            <endpoint 
                address="%MyEndPointAddress%" ... />
            . . .
        </service>
    </services>
</system.serviceModel>

Any knowledge will be highly appreciated.

To change endpoint address you will need to know EndPointName and ContractName. This values are found in your config file inside WCF configuration. Then you can use following code:

    void SetNewEndpointAddress(string endpointName, string contractName, string newValue)
    {
        bool settingsFound = false;
        Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        ClientSection section = config.GetSection("system.serviceModel/client") as ClientSection;
        foreach (ChannelEndpointElement ep in section.Endpoints)
        {
            if (ep.Name == endpointName && ep.Contract == contractName)
            {
                settingsFound = true;
                ep.Address = new Uri(newValue);
                config.Save(ConfigurationSaveMode.Full);
            }
        }
        if (!settingsFound)
        {
            throw new Exception(string.Format("Settings for Endpoint '{0}' and Contract '{1}' was not found!", endpointName, contractName));
        }
    }

Happy coding!
