I have a plain old CLR object which is essentially a wrapper for two entity framework objects, I'm doing this so I can pass this wrapper object to a strongly typed view in the MVC framework. My foo wrapper class is very simple:
public class FooWrapper
{
public FooWrapper(Foo f, Bar b)
{
this.FooObject = f;
this.BarObject = b;
}
public Foo FooObject { get; private set; }
public Bar BarObject { get; private set; }
}
What I have so far for my ListFoosWithBars function is as follows:
public IEnumerable<FooWrapper> ListFoosWithBars(int userID)
{
IEnumerable<Bar> tempBar = ListBarsByUserID(userID);
IEnumerable<FooWrapper> results = (from f in _entities.FooSet
join b in tempBar on f.ID equals b.foos.ID
select new FooWrapper(f, b));
return results;
}
This doesn't work because evidently LINQ to Entities doesn't support parametrized initialization, an exception is thrown that says just that: "Only parameterless constructors and initializers are supported in LINQ to Entities." I was wondering if there is another way to achieve this same result?
