How to use a profile when publishing from code

[sam-wheat]

I have variables I need to substitute during publish. I use XML publish profile files. I would like to use those files when publishing from code. I believe the object I need to use is DacProfile. I don't know how to use it in my code as shown below:

    var dacpac = DacPackage.Load("...");
    var dacpacService = new DacServices(connectionString);
    dacpacService.Publish(dacpac, "MyDB", new PublishOptions());
