Display List Of Values In MVC Detail View?

I am new to web apps, MVC, and LinqToSql. I created an MVC web app using the NerdDinner tutorial as a guide. I'm now adding many-to-many relationships to it. And am just running into walls at every step. I have a multiselect list in the Edit and Create views. For the Detail and List views I would like to list the selected values.

I have 3 tables: Company, Subcontract, and a link table CompanyToSubcontract. I have code which gets the guid of my selected companies from the CompanyToSubcontract table which is used elsewhere in my code. I do not know how to display it.

Should I write another function to get the Company names from the Company table? Do I pass the list of names to the SubcontractDetail view and then somehow loop through it there?

Same questions with the SubcontractIndex view. The Index view is in table format, I'd like to have a "Company" column which has a comma separated list of the companies for each subcontract row.

subcontract subcontract = subcontractRepository.GetSubcontract(id);
IEnumerable<Guid> cmpny = subcontractRepository.GetSubcontractCompanies(subcontract.subcontract_id);
if (subcontract == null)
return View("NotFound");
else
{
return View("Details", subcontract);
}
}

public ActionResult Index()
{
var subcontracts = subcontractRepository.FindAllSubcontracts().ToList();
return View("Index", subcontracts);
