Start session in specific company C#

Is there a way to start a session in a specific company? If so, how do you do this?

Is it somewhere here?

 _session = new Ice.Core.Session(<USER>, <PASSWORD>, Session.LicenseType.Default,configFile);
       
        var iLaunch = new ILauncher(_session);
        oTrans = new Transaction(iLaunch);

Where from? There are about 100 places to start a session from. Need better context. Generally you need to set the session.Company field

Your in the right spot, just need to pass more information to your session.

EpiSession = New Session(User, Password, “”, Ice.Core.Session.LicenseType.Default, configFile, False, Company, Site)
