Question

I need to create an address string in app.config as:

<client>
       <endpoint address="http://ServerName/xxx/yyy.svc"
                    binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IClientIInfoService"
                    contract="DocuHealthLinkSvcRef.IClientIInfoService" name="BasicHttpBinding_IClientIInfoService" />
</client>

The ServerName need to be entered by the user during installation.
For that i have created a new UI dialog in the Installer. I have also written an Installer.cs class and overrided the install () as:

public override void Install(System.Collections.IDictionary stateSaver)
        {

            base.Install(stateSaver);

            string targetDirectory = Context.Parameters["targetdir"];

            string ServerName = Context.Parameters["ServerName"];

            System.Diagnostics.Debugger.Break();

            string exePath = string.Format("{0}myapp.exe", targetDirectory);

           Configuration config = ConfigurationManager.OpenExeConfiguration(exePath);

            config.AppSettings.Settings["ServerName"].Value = ServerName;

            config.Save();
        }
    }

But how do i use this ServerName in my app.config to create the specified string.
I’m working on VS2010.

Assuming you are using the full ServiceModel section group in the app.config

Essentially you follow these steps:

1. Load ServiceModel config section
2. Get Client Section
3. Get ChannelEndpoint Element
4. Change Address value by replacing string “ServerName” with entered value
5. Set Address attribute to new value

6. Save config

   public override void Install(System.Collections.IDictionary stateSaver)
   {
   
       base.Install(stateSaver);  
   
       string targetDirectory = Context.Parameters["targetdir"];  
   
       string ServerName = Context.Parameters["ServerName"];  
   
       System.Diagnostics.Debugger.Break();  
   
       string exePath = string.Format("{0}myapp.exe", targetDirectory);  
   
       Configuration config = ConfigurationManager.OpenExeConfiguration(exePath);  
   
       config.AppSettings.Settings["ServerName"].Value = ServerName;  
   
       //Get ServiceModelSectionGroup from config  
       ServiceModelSectionGroup group = ServiceModelSectionGroup.GetSectionGroup  (config);
   
       //get the client section
       ClientSection clientSection = group.Client;
   
       //get the first endpoint
       ChannelEndpointElement channelEndpointElement = clientSection.Endpoints[0];
   
       //get the address attribute and replace servername in the string.
       string address = channelEndpointElement.Address.ToString().Replace("ServerName", ServerName);
   
       //set the Address attribute to the new value
       channelEndpointElement.Address = new Uri(address);
   
       config.Save();
   }
